    摘要： The invention relates to a handle for a hand-held power tool, comprising a hollow grip element (2), a clamping holder (3), and a damping device (6). The clamping holder (3) further comprises a housing (4) and a tensioning belt (5), wherein the tensioning belt (5) is disposed about a partial region of the hand-held power tool, the damping device (6) comprises a sleeve (7) and a sleeve-like damping element (8) and is disposed in the interior of the hollow grip element (2), wherein the sleeve-like damping element (8) is disposed on the exterior of the sleeve (7) and an interior surface of the hollow grip element (2) comes in contact with the sleeve-like damping element (8). The invention further provides an attachment element (9, 11), which is connected to the tensioning belt (5) and fixed to the sleeve (7).

    摘要： The invention relates to a handheld machine tool, especially a drill hammer and/or a percussive drill. Said machine tool comprises a hammer tube (15) which is rotatably arranged in a housing (11) and is used to rotatably drive a tool receiving element (16) holding a tool in a rotationally fixed and axially displaceable manner, a motor-driven drive toothed wheel which is arranged on the hammer tube (15) and is used to rotatably drive the hammer tube (15), and a latch coupling (24) comprising concentric coupling parts that are engaged by means of torque-transmitting elements (26) and can be latched against a radial force of a coupling spring when a threshold torque is exceeded. One of said coupling parts is formed by the hammer tube (15), and one is a motor-driven percussive mechanism (18) which is arranged in the hammer tube (15) and is used to drive the tool in a translatory manner. The aim of the invention is to produce a robust latch coupling (24) that can be used both for a hammer tube (15) that is axially fixed in relation to the housing (11) and for a hammer tube (15) that can be axially displaced in relation to the housing (11), said hammer tube (15) being embodied as a single component or in several parts. To this end, the other coupling part of the latch coupling (24) is formed by a coupling sleeve (25) that is arranged on the hammer tube (15) in a sliding manner and can be coupled to the drive toothed wheel (14) for the fixed rotary connection.

    摘要： The invention relates to a drill hammer or a paving breaker comprising a housing (10), a tool holder (11) and an insulating air cushion striking train (12). The striking train (12) comprises a motor-driven piston (21) which can move back and forth, a hammer (22) which is driven by the piston (21) and a hammer tube (14) which guides the piston (21). An idling control opening and (31) an idling spring (35) are provided in order to control idling in the insulating air cushion striking train (12) when the tool is lifted from a processing point. In order to ensure an idling via a large idling path of the striking train (12) while at the same time ensuring low production costs and creating a constructively simple device, the hammer tube (14) is secured in the housing (10) in such a manner that it cannot be axially displaced and the tool holder (11) is embodied in such a manner that it can be axially displaced. The idling spring (35) is supported on the tool holder(11) and on a fixed stop ring (26) which cannot be displaced axially.
