An exchangeable tool holding fixture that can be operated very easily is characterized in that at least one displaceably mounted profiled body (15) and at least one profiled recess (7) are shaped and arranged on an output spindle (1) or on the tool holding fixture (11) of the portable power tool in such a manner that when sliding the tool holding fixture (11) onto the output spindle (1), the at least one profiled body (15) engages inside the at least one profiled recess (7) with which both an axial locking as well as rotational drive of the tool holding fixture (11) ensues on the output spindle (1). In addition, means (6, 8, 14) are provided that guide the profiled body (15) into the profiled recess (7) by a rotary and pushing motion of the tool holding fixture (11) on the output spindle (1).

The invention relates to a handle device for a hand-held power tool, which comprises an operating mode-switchover device and a drive device for driving an insert tool in different operating modes, with at least one spring element (18) and a handle unit (22) which is mounted on a machine housing (20) so as to be movable at least to a limited extent and which is at least partially decoupled in terms of vibrations via the at least one spring element (18) with respect to the machine housing (20). It is proposed that the handle device comprise at least one backplate (38) which is provided in order to secure the spring element (18) in form- and force-locking manner.

The invention relates to a device main switch for electric machine tools, particularly electric hand tools, with a rocker switch and an electric switch element. The rocker switch comprises at least two switch positions along a first actuating direction. The electric switch element comprises a switch housing and an actuating device with a moveable actuating element. The electric switch element comprises a longitudinal extension that is aligned at an angle, particularly perpendicular to the first actuating direction. With the device main switch according to the invention the moveable actuating element comprises a second actuating direction that is oriented parallel to the longitudinal extension of the electric switch element.

The invention relates to a drill hammer comprising a hammer tube (13) which is rotationally drivable inside a housing (10), a striking train (14) which is arranged in the hammer tube (13) and is provided with a piston (15) which can be driven in a reciprocating movement, in addition to an operating mode commutator (35) for the operating modes 'impact drilling ' and 'chiselling '. The hammer tube (13) is decoupled from the rotary drive when in the 'impact drilling ' operating mode and is secured in a non-rotative manner in the housing (10) when in the 'chiselling' operating mode.
