Knife holder for electric kitchen appliances

A portable power tool, in particular a hand-held planing machine, includes at least one workpiece contact unit and at least one handle unit. The workpiece contact unit has at least one workpiece contact surface, and the handle unit has at least one main handle. The main handle has at least one maximum distance point that, in a direction extending at least substantially perpendicularly to a workpiece contact surface, has a maximum distance from the at least one workpiece contact surface. The maximum distance is less than 150 mm.

Portable power tool

An extraction connection system for portable machine tools includes at least one tool connection element, at least one suction apparatus connection element, and at last one fixing unit. The at least one tool connection element is configured to be connected to the at least one suction apparatus connection element. The at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.

Extraction connection system

A portable machine tool, in particular a hand-held planing machine, includes at least one workpiece positioning unit and at least one insert tool unit. The at least one workpiece positioning unit has at least one workpiece positioning surface. The at least one insert tool unit projects at least partially over the at least one workpiece positioning surface in order to permit processing of workpiece. The portable machine tool further includes at least one adjustment unit that is configured, in at least one state, to set at least one orientation of one or more of the insert tool unit and the workpiece positioning surface relative to one another.

Portable machine tool

A guiding system for portable machine tools has at least one guiding apparatus which is fixable on a portable machine tool. The guiding system also has at least one positive guidance unit to which the at least one guiding apparatus is connectable in a positive-locking manner to positively guide the portable machine tool. The guiding system also has at least one position fixing unit configured to fix a position of the at least one guiding apparatus on the at least one positive guidance unit. The at least one position fixing unit has at least one fastening unit configured to releasably fix the at least one position fixing unit on the at least one guiding apparatus.

Guiding system

A spindle locking device for a portable machine tool includes a locking unit and a movement activation unit. The locking unit has a movably mounted locking element configured to lock a spindle of the portable machine tool in at least one direction, and an operating element configured to actuate the locking element. The movement activation unit is configured to pretension the locking element in a direction towards a locking position, at least when the operating element is in an unactuated position.

Spindle locking device

A portable planing machine has a rotatably mounted planing shaft in a housing. The planing shaft is driven by a drive motor. Furthermore, a fan wheel is configured to generate a cooling airflow. At least one cooling duct is integrated into the planing shaft. An outflow opening of the cooling channel is at a greater radial spacing from the rotational axis than an inflow opening of the cooling duct.

Portable planing machine

A hand-held power tool is equipped with a dust extraction device which includes a dust box for holding dust. A closing flap is arranged in a tube section which lies in the flow path to the dust box, and this closing flap can be adjusted between the closed position and the open position. The closing flap is pivotably held in the region of the inner wall of the tube section and can be opened in the direction of the dust box. In the closed position, the closing flap bears against a stop which protrudes into the tube section, extends at an angle with respect to the direction of flow through the tube connection piece, and forms a stop line or stop area against which the closing flap correspondingly bears.

Handheld power tool having a dust extractor

A guide device to guide portable power tools on a constrained guidance unit includes at least one base body unit and at least one guide unit. The base body unit, in at least one operating state, is disposed on a side of a seating unit of a portable power tool that faces away from a housing of the portable power tool. The guide unit is configured to positively connect to the constrained guidance unit. The guide unit is also movably mounted to the base body unit.

Guide device

The invention relates to an electric tool, in particular a hand-held electric tool, having a housing, which has a rear housing part and at least one front housing part arranged in front of the rear housing part in the longitudinal direction of the electric tool, and an electric drive motor having an armature shaft that extends in the longitudinal direction of the electric tool. The armature shaft is rotatably mounted together with a rear bearing arranged at the rear housing part. According to the invention, the rear bearing is designed as a fixed bearing.

Hand-held power tool

An auxiliary handle for a motor-driven hand tool has a mounting device which forms an upper region and provides a force-transmitting and/or form-locking connection to a hand tool; a handle forming a lower region, a damping element forming an intermediate region and located at least locally between the mounting device and the handle, the damping element having a damping material with which, during an operation of a hand tool, it dampens vibration transmitted through the mounting device to the handle, the damping element in its damping region acting for damping having at least one reinforcing region that has a lower deformability than a remaining part of the damping region and during deviations of the handle in at least two different directions relative to the mounting device causes differently great elastic counter forces.

Auxiliary handle, and hand power tool provided therewith

A hand-held power tool, in particular an electrical hand-held power tool (), includes a drive motor (), a tool shaft (), and a first overload clutch () for limiting the maximum torque that acts on the tool shaft (). Preferably, the hand-held power tool also includes a second overload clutch ().

The invention relates to a power tool having a change-speed gear device comprising a plurality of gears () for adjusting on demand power stages of a drive, wherein an overload protection can be coupled to the gears (). According to the invention, the device comprises at least one gear () in which the overload protection function can be forcibly deactivated. The invention also relates to an overload protection.

Power tool and overload protection

A suction extraction system of an electric power tool has a housing, a cup-shaped part of the housing, a gear-containing chamber, a suction extractor for receiving air contaminated with drilling material, and a suction conduit for extracting the air by suction, the suction extractor being connectable to the electric power tool via a connection element, wherein the suction conduit is located at least partially inside the housing of the electric power tool and is sealed from outside by a self-closing closure.
