Abstract: A hand power tool has a housing, and drive motor accommodated in the housing, a tool receptacle in which a tool is guided, a gear mechanism, a driving gear, and rotary sleeve arranged so that via the gear mechanism, the driving gear, and the rotary sleeve the tool receptacle is drivable in rotation, a crank drive mechanism and a hammering mechanism located inside the rotary sleeve so that the tool receptacle is drivable through the crank drive mechanism and the hammering mechanism translationally, and a safety coupling provided between the driving gear wheel and the rotary sleeve and formed so that the safety coupling separates if a limit torque is exceeded, the safety coupling being formed as an overlock coupling seated on the rotary sleeve and having two axially adjacent coupling parts that mesh in a form-locked manner by torque-transmitting transmission elements and are overlockable if the limit torque is exceeded counter to an axially acting elastic force, one of the coupling parts being a part associated

Abstract: A hand power tool, in particular a drill hammer or jackhammer, is disclosed, which has a guide tube (11), a tool holder (24) that can be attached interchangeably to the guide tube (11), and a locking device (23) that locks the tool holder (24) to the guide tube (11), the locking device being manually releasable by means of an axial displacement of a slide sleeve (34) oriented away from the tool holder (24). To achieve a compact connection construction, which is economical in production terms, between the interchangeable tool holder (24) and the hand power tool, the tool holder (24) is embodied as insertable by an end portion (241) into a guide portion (111) embodied on the front end of the guide tube (11), in the inner wall thereof (FIG. 1).

Abstract: The invention relates to a handle for an electric tool. The handle according to the invention has at least one detecting unit.

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.

Abstract: A tool holder for a power tool, such as a drill hammer, a chisel hammer, and both, includes a striking mechanism for strikingly driving a tool, a base body, a drive part on which the base body is releasably mounted, at least one locking body for releasably mounting the base body on the drive part, a component having a throughgoing passage in which the at least one locking body is arranged, a securing body which radially fixes the at least one locking body in its engaging position, an actuating element for unlocking the securing body from its locking position to an unlocking position for radially reieasing the at least one locking body, and at least one holding element which holds the at least one locking body in the unlocking position of the securing body in the throughgoing passage. The holding element is lowered or lowerable into the component having the throughgoing passage and is overrun by the securing body.

Abstract: The invention relates to a hand power tool, in particular a percussion hammer, having a housing (10), a hammer barrel (12), and a tool receptacle (14) that is fixable in the direction of rotation (18) via at least one locking body (16).

Abstract: The invention is based on a hand power tool comprising a striking element via which a tool (10) in a tool holder (12) can be driven in striking fashion, which said tool holder can be detachably secured—via its body (14)—to a drive part (16) via at least one locking element (18), which said locking element, in its engaged position, is capable of being fixed in position radially by a retaining element (20), which said retaining element is capable of being guided by means of an operating element (22) out of its locked position into a release position that radially releases the locking element (18) in order to release the tool holder (12), whereby the retaining element (20) is capable of being moved by a corresponding component (14) into its release position against a spring force of a spring element (24) when the tool holder (12) is pushed onto the drive part (18).

Abstract: A tool holder for a power tool formed as a hammer selected from the group consisting of a drill hammer, a chisel hammer and both, the tool holder has a striking mechanism for strikingly driving a tool, a base body, a drive part on which the base body is releasably mounted, at least one locking body for releasably mounting the base body on the drive part, a component having a throughgoing passage in which the at least one locking body is arranged, a securing body which radially fixes the at least one locking body in its engaging position, an actuating element for unlocking the securing body from its locking position to an unlocking position which radially releases the at least one locking body, at least one holding element which holds the at least one locking body in the unlocking position of the securing body in the throughgoing passage, the holding element is lowered or lowerable into the component having the throughgoing passage and is overrun by the securing body.
