The striking pin (16) is arranged in a bearing (29). The striking pin (16) has a circumferential surface (25) and a stop surface (27) facing in the striking direction (11). The bearing (29) has a sleeve (30) arranged coaxially to the working axis (10) as well as a catcher (32). The circumferential surface (25) of the striking pin (16) is installed so as to slide on the inside of the sleeve (30). The catcher (32) is arranged in the striking direction (11) of the stop surface (27) of the striking pin (16) in order to limit the movement of the striking pin (16) in the striking direction (11). A connecting link (35) is provided for purposes of causing the striking pin (16) to execute a rotation relative to the bearing (29) when the striking pin (16) moves in the striking direction (11). The connecting link (35) has a flank (42; 53) on the striking pin (16) and another flank (49; 52) on the bearing (29), whereby the two flanks (42; 53, 49; 52) that rest against each other during the movement rise in the striking direction (11) in the same circumferential direction (39). |
