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). It is proposed that the retaining element (20) is captively held on the drive part (16) and is capable of being guided into its release position by the operating element (22) in the push-on direction (26) of the tool holder (12) against a spring force of a spring element (24).
A hand power tool, in particular a drilling and/or chipping hammer, 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),
