A hand-held power tool includes a housing in which a drive unit for actuating a tool holder is arranged. The housing forms a handle for holding the hand-held power tool. At least one fastening region is associated with the housing to which a safety loop for securing the hand-held power tool against falling can be fastened. The at least one fastening region has an optical and/or haptic marking element for marking the at least one fastening region.

A hand-held power tool includes a housing in which a drive unit and an impact-mechanism unit are arranged. The hand-held power tool further includes a tool-receiver interface configured to releasably connect with a tool receiver, the tool receiver configured as a stirrer-basket receiver. A user interface is configured to set at least one of a rotary-hammer mode and a stirring mode for the hand-held power tool.

Hand-held power tool

A power-tool cooling apparatus for a portable power tool includes a first fan configured to generate a first cooling fluid flow to cool a drive unit of the portable power tool, and a second fan that generates a further cooling fluid flow to cool an electronics unit of the portable power-tool. A third fan generates a third cooling fluid flow to cool a second electronics unit of the power-tool, and supplies cooling fluid to the first cooling fluid flow.

Power-tool cooling apparatus

A hand-held power-tool device includes at least one coupling device, which has at least one contact receiving region, and which is configured to couple an optional additional module to at least one energy supply unit, in at least one operating state. The at least one contact receiving region has (i) at least one receiving opening configured to receive a corresponding contact element of the optional additional module, and (ii) at least one dirt removal opening.

Hand-held power-tool device

A contact holder device for a hand-held power tool includes at least one main body that is disposed inside a housing unit of the hand-held power tool. The main body accommodates or fixes contact elements configured to transmit data signals and/or electrical energy. The main body has at least one disposition plane and at least one group of contact elements are disposed in the disposition plane. The main body has at least one further disposition plane and at least one further group of contact elements are disposed in the further disposition plane. The further disposition plane is disposed in an offset manner in relation to the disposition plane.

A power-tool cooling apparatus for a portable power tool comprises at least one cooling unit configured to generate a cooling fluid flow to cool a drive unit of the portable power tool, and at least one further cooling unit configured to generate a further cooling fluid flow. The at least one further cooling unit is designed to differ from the at least one cooling unit.

A hand-held power tool suction extractor apparatus comprises at least one fastening unit configured to mount on a hand-held power tool. The at least one fastening unit includes at least one holding element configured to be positioned on the hand-held power tool and at least one fastening element configured to exert a holding force on the at least one holding element. The at least one fastening unit also includes at least one movably mounted position fixing element configured to fix the at least one fastening element.

A drill hammer for the three operation modes of drilling, chiseling, and hammer-drilling has a motor with a motor shaft; a gear with an intermediate shaft, a driving gear wheel, a toothed slaving shaft , a shifting hub, and a driven gear wheel; a percussion mechanism with a wobble disk and a wobble gear wheel; and a driven shaft with a driving gear wheel and a drill chuck. The gear is configured to be changed over easily without axial displacement of running gears that mesh with one another so that the drill hammer is more robust, shorter or more compact, and lighter in weight. The drill hammer is thus simply and economically constructed and whose efficiency is not impaired by the gear shifting mechanism.

Drill hammer with three modes of operation

The invention relates to a hand-held power tool, in particular a hammer drill which has a hammer drive, a rotary drive, a switching device, and a main output element. The switching device has a slide mechanism, which is designed for switching between different operating modes. According to the invention, the slide mechanism has at least one coupling element, which in at least one operating mode is directly coupled to a coupling element, the latter being rotationally fixed to the main output element.

An electric hand-held power tool has a housing, a double-shelled handle attached axially to the housing, a selector ring pivotably located in the housing, and an actuating element supported by the selector ring and swivelable manually. The housing and the handle have a line connecting domes oriented parallel to an axis of the housing and located in a parting plane region between the housing and the handle for receiving connecting units. The connecting domes include centering elements for guiding and exactly positioning the handle shells when the handle shells are attached individually to the housing.

Electric hand-held power tool

An electric motor includes carbon brushes () disposed in a holder () that are pressed by means of a spring force () in a radial direction against a jacket face of a cylindrical collector () that is fixed to an armature shaft () of the motor. The holder () for the carbon brushes () can be removed from the motor with little effort as a result of a provision of covering means () that cover a pivot bearing () of the armature shaft () to protect it against the entry of dirt on a side of the covering means () facing the holder () for the carbon brushes (), provided with one or more chamfers () in such a way that the carbon brushes () slide over the covering means () as the holder () is being pulled off and that the carbon brushes () thereby are thrust radially outward counter to the spring force ().

Electric motor with a housing for at least two carbon brushes

A power tool has an electric motor, a brush element that is supported rotatably for switchover between clockwise operation and counterclockwise operation of the electric motor and includes a brush holder, and a switch unit, embodied separately from the brush element and connected in form-locking fashion to the brush element, which switch unit has an actuating element for actuation by a user, can be slipped in the axial direction onto the brush element, located on the electric motor, and is connected in the axial direction to the brush element.

Power tool

An electric hand tool is disclosed which has a gt (), received in a housing (), with a gear shaft () and also has at least one radial bearing () for rotary support of the gear shaft (), the inner bearing ring () of the radial bearing being fixed on the gear shaft () and the outer bearing ring () of the radial bearing being fixed in a bearing box () disposed in the housing (), in each case being fixed axially nondisplaceably. For simple assembly of the gt () without tools, the outer bearing ring () of the radial bearing () rests with a sliding seat in the bearing box () and is fixed by means of a clamping bracket () fixed to the bearing box ().

Electric hand tool

The invention is based on an electrical machine with a rotatable brush plate (), which is held in its end positions by means of at least one holding mechanism () that acts in the circumference direction (). The invention proposes that the holding mechanism () have at least one device () that loads the brush plate () in the circumference direction ().

Electric machine and manual machine tool comprising the same

An electric hand power tool formed as a hammer drill or an impact hammer drill has a housing, a drive transmission received in the housing and having an intermediate transmission for turning a tool, an impact mechanism with a swinging drive for delivering axially oriented impacts to the tool, and a drive shaft, a transmission toothed wheel fixed on the transmission shaft for turning the latter, a drive bearing provided on the swinging drive and loosely arranged on the transmission shaft, a manually releasable coupling provided for switching off the impact mechanism and connecting the drive bearing with the transmission shaft for a rotation transmission, a crank-shaped flat switching plate provided for releasing the coupling and turnably supported on a receiving dome arranged above the transmission shaft, a drive pin operative for turning the switching plate under the receiving dome and engaging the switching plate, and a handle.
