The output shaft is configured to be releasably connected to an insert tool of the handheld power tool. The drive unit is configured to transmit a movement to the output shaft. The securing element is configured to secure the securing ring. The securing element has a recess which is provided to surround the securing ring in the radial direction in at least one operating state.

Handheld power tool

A hand-held power tool includes a housing, a filter support, a plurality of securing element, and an actuating unit. The filter support has receiving openings, at least one first fixing element, and at least one second fixing element. The receiving openings are configured to receive filter elements configured to seal the hand-held power tool against a penetration of dust into the housing of the hand-held power tool. First and second fixing elements are fixable to corresponding securing elements arranged on the hand-held power tool, and are configured to releasably fix the filter support to the housing. The actuation unit is actuatable to release the filter support from the hand-held power tool.

Hand-held power tool comprising a filter support

A hand-held power tool, in particular an angle grinder, includes a drive unit, a machine housing, and a user interface unit. The machine housing surrounds the drive unit. The drive unit is configured to transmit a motion to an output unit. The user interface unit is configured to operate the hand-held power tool, and is either (i) positioned on an inner element of the hand-held power tool, in particular a flat outer surface of the inner element, or (ii) connected to the inner element, in particular the flat outer surface of the inner element.

Hand-held power tool

A filter support for a handheld power tool includes at least one filter support element, a first fastening element, and a second fastening element. The filter support element includes at least one receiving opening configured to receive a filter element. The filter elements of the filter support are preferably associated with air inlet openings of the handheld power tool and are configured to filter dust particles and/or material particles from a cooling air flow. The filter support can be fastened to a handheld power tool via the first and second fastening elements. The first and the second fastening elements of the filter support can be connected to each other. Advantageously, no fastening elements are provided on the handheld power tool.

Filter support for a handheld power tool

In one embodiment, a system includes a HMI module. The HMI module includes a first external application unit that has first external application unit. The first external application unit has a first interface for the HMI module. The HMI module further includes a second external application unit that has a second interface for the HMI module. The HMI module can correspond with both the first interface and the second interface.

System having at least one HMI module

An electric power tool has a tool receptacle and a tool housing in which a drive motor for driving the tool receptacle is arranged. The drive motor is switchable on and off via an electric switch. An operating part for indirectly actuating the switch is arranged on the tool housing and extends approximately parallel to a longitudinal axis of the tool housing. The operating part is lever-like and is pivotably arranged on the tool housing. An actuating member of the switch is displaceable approximately parallel to the longitudinal axis by an actuating force that acts on the operating part approximately perpendicularly to the longitudinal axis. The drive motor is switched on by the actuating force acting on the operating part against a restoring force of the switch, and the drive motor is switched off automatically, via the restoring force, when the operating part is released by a user.

Electric power tool

A hand-held power tool includes an electric motor, a housing, and a housing cover. The housing includes an opening located in the vicinity of carbon brushes of the electric motor, such that the carbon brushes can be removed through the opening in the housing. The housing cover includes air inlets through which cooling air can flow into the interior of the housing. The opening in the housing is detachably closed by the housing cover.

Housing cover for a hand-held power tool

An electric power tool has a tool housing and a drive motor configured to drive an insert tool. The drive motor is switched on and off by an electric switch actuated by a switching device. The switching device has at least one switching slide with a first end and a second end. The first end has a receiver configured to receive an operating element. The second end is connected to an actuating element configured to actuate the electric switch. The receiver has a first region that tapers into a second region. The operating element has a connecting web connected to a holding element. The holding element has an extent that is less than or equal to an assigned extent of the first region. The connecting web has an extent that is less than or equal to an assigned extent of the second region.

Electric power tool having a switching device

A machine tool switching device, in particular for portable machine tools, includes at least one switching unit that has at least one movably mounted operating element for actuating a mechanical, electrical, and/or electronic switching element. The machine tool switching device further includes at least one blocking device for blocking at least one movement of the operating element. The blocking device includes at least one movably mounted release element provided to lift the blockage of the operating element. The release element is mounted on the operating element so as to be movable in a translatory manner.

Machine tool switching device

A hand-operated machine tool device, in particular for an angle grinder, includes a housing region and at least one operating element. The housing region is at least substantially rod-shaped and is configured to be used as a main gripping element. The at least one operating element extends in the housing region in a main extension direction of the housing region. The hand-operated machine tool device also has a least one mounting which supports at least one operating face of the at least one operating element such that the at least one operating element is configured to pivot about at least one axis aligned at least substantially parallel to the main extension direction.

Hand-operated machine tool device

A tool machine has a housing assembled by two separate housing parts and an air directing element arranged in the housing, wherein the air directing element is implemented independently from a connection device for connecting the housing parts. The air directing element is forced by a housing part axially in a seat in the other housing part, wherein in the transmission path between the housing parts and the air directing element a spring element is arranged.

Machine tool, in particular hand machine tool

A power tool switching device, in particular for portable power tools, includes at least one switching unit having at least one movably mounted control element configured to actuate a mechanical, electrical and/or electronic switching element. The power tool switching device further includes at least one guide unit, which, upon an actuation of the control element along a direction of main extent of the control element, is configured to convert a movement of the control element along the direction of main extent at least into a movement of the control element running transversely in relation to the direction of main extent.

Power tool switching device

A power tool, particularly a hand power tool, has a motor housing and a housing cover, in which a brush cover can be removably inserted. Corresponding form-fitting elements are arranged on the motor housing and on the housing cover, said elements being connected to each other in a form-fitting manner in the assembled position.
