    Abstract: A very easy-to-actuate, replaceable tool fitting is comprised in that at least one movably supported profiled body (15) on an output spindle (1) or on the tool fitting (11) of the hand-held power tool and at least one profiled recess (7) on the output spindle (1) or on the tool fitting (11) are shaped and situated in such a way that when the tool fitting (11) is slid onto the output spindle (1), the at least one profiled body (15) engages in detent fashion in the at least one profiled recess (7), achieving both an axial locking and a rotary driving of the tool fitting (11) in relation to the output spindle (1) and means (6, 8, 14) are provided, which, through a rotating and sliding motion of the tool fitting (11) on the output spindle (1), guide the profiled body (15) into the profiled recess (7).

    Abstract: A hand-held power tool includes a main element with a normal axis which extends perpendicularly to a tool axis and through a center of gravity. A handle is supported in the plane of motion defined by the tool axis and the normal axis such that it is movable relative to the main element. A spring unit connects the handle with the main element, and has a spring element to define a trajectory of at least one portion of the handle in the plane of motion under the influence of a load force triggered when the handle is moved out of a neutral position and approaches the stationary main element. A rotary element defines a joint-free rotation axis, about which the handle rotates in the plane of motion when a motion takes place relative to the main element.

    Abstract: A hand power tool selected from the group consisting of a drill hammer and an impact hammer has an exchangeable tool holder, a guide pipe which receives the tool holder at its free end, a locking device arranged on the guide pipe and operative manually for fixing the tool holder on the guide pipe in a defined locking position assumed by the tool holder on the guide pipe, so that the locking position is arranged before a mounting position in a displacement direction of the tool holder, in which mounting position the tool holder is held unlocked on the guide pipe, the locking device being provided with means activatable by a release of the locking device and providing a displacement of the tool holder to the mounting position.
