    摘要： 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.

    摘要： The invention relates to a handle device for a hand-held power tool, which hand-held power tool has an operating-mode switching device and a driving device for driving an insert tool in different operating modes, the handle device comprising at least one spring element (18) and a handle unit (22) attached in at least limitedly movable manner to a power tool housing (20). The handle element is at least partially vibrationally decoupled from the power tool housing (20) by means of the at least one spring element (18) and has a switch actuator (24) for starting up the driving device (14), wherein the switch actuator (24) can be switched between two switching positions in both a monostable manner and a bistable manner. According to the invention, the handle device has an intermediate plate (26), which is provided in the power tool housing (20) and which at least accommodates the spring element (18) at one end, and a control element (28), by means of which the switch actuator (24) interacts with the operating-mode switching device (12) in such a way that bistable switching is not possible in certain operating modes of the switch actuator (24).

    摘要： The invention relates to a hand power tool device having a hammer tube (12a; 12b; 12c) and a B-impact damping system (14a; 14b; 4c) comprising at least one damping means (16a; 16b; 16c) provided for damping recoil energy. The invention proposes that the damping means (16a; 16b; 16c) is disposed at least partially radially outside of the hammer tube (12a; 12b; 12c) in at least one operating state.
