A tool receptacle for a hand-held power tool, in particular for a demolition hammer or chisel hammer, includesa receptacle element for receiving a tool, and a locking element which for locking the tool in the tool receptacle is mounted so as to be eccentric and rotatable on the receptacle element, wherein the locking element with the aid of rotating the latter about the receptacle element is capable of being moved from an unlocked state in which the tool is retrievable from the receptacle element to a locked state in which the locking element encompasses the tool in a form-fitting manner, and vice versa.

It is an object of the invention to provide an impact tool having a rational mechanism in an idling state. According to the representative invention, in an idling state defined as a state in which a tool accessory 119 is not pressed against a workpiece and an impact bolt 145 transmits a striking force to the tool accessory 119, the tool accessory retainer 510 moves with respect to a tool accessory holder 117 by movement of the tool accessory 119 in the longitudinal direction, so that the striking force is cushioned.

A hand-held power tool includes a tool receiving area which has an inner receiving area that is designed to receive an insert tool and also includes a striking mechanism for applying striking pulses to the insert tool. A locking bolt is provided in order to lock the insert tool, wherein the locking bolt is connected to an operating element which is designed to position the locking bolt such that the insert tool is locked in a locked position and is unlocked in an unlocked position in order to be removed from the inner receiving area, and the locking bolt is paired with at least one damping element for at least partly damping a force acting on the insert tool in an idle running state of the hand-held power tool. The tool receiving area is paired with a receiving chamber in which the locking bolt and the at least one damping element are arranged. The locking bolt is at least partly received in a receiving area of a force transmission element, and the at least one damping element is arranged directly on the force transmission element in the receiving chamber.

Various exemplary surgical impacting tool interfaces and methods of using surgical impacting tool interfaces are provided. In general, a surgical impacting tool includes a locking assembly configured to releasably attach to an adapter. In response to engagement with the adapter, the locking assembly is configured to move from an unlocked configuration, in which the adapter is not releasably attached to the surgical impacting tool (nor is any other adapter releasably attached to the surgical impacting tool via the locking assembly), to a locked configuration, in which the adapter is releasably attached to the surgical impacting tool via the locking assembly. The locking assembly is configured to receive the adapter in a longitudinal direction along a longitudinal axis defined by the locking assembly and to automatically lock the adapter to the surgical impacting tool.

A system configured to couple a hydraulic hammer and tool is disclosed. A hydraulic hammer may include a housing defining a chamber, elongate along a longitudinal axis, configured to receive a tool. The chamber may comprise an opening through which the tool may be inserted. A plurality of upper splines and a plurality of lower splines may be disposed, parallel to the longitudinal axis, on an inner surface of the chamber. A locking mechanism, comprising a rotatable locking ring, may be disposed within the chamber between the plurality of upper splines and the plurality of lower splines. The locking ring may comprise a plurality of locking ring splines disposed on an inner surface of the locking ring, wherein the plurality of locking ring splines are configured to align with the plurality of upper splines and the plurality of lower splines when the locking ring is rotated to an unlocked state.

A hand-held power tool includes a tool receiving area which has an inner receiving area that is designed to receive an insert tool and also includes a striking mechanism for applying striking pulses to the insert tool. A locking bolt is provided in order to lock the insert tool, wherein the locking bolt is connected to an operating element which is designed to position the locking bolt such that the insert tool is locked in a locked position and is unlocked in an unlocked position in order to be removed from the inner receiving area, and the locking bolt is paired with at least one damping element for at least partly damping a force acting on the insert tool in an idle running state of the hand-held power tool. The tool receiving area is paired with a receiving chamber in which the locking bolt and the at least one damping element are arranged. The locking bolt is at least partly received in a receiving area of a force transmission element, and the at least one damping element is arranged directly on the force transmission element in the receiving chamber.
