摘要： A device on hand-held tool-driving machines for the coupling of pounding and/or drilling tools is proposed, wherein on the tool shank (11) and the tool holder (10) are located at least three couplings comprising grooves (17, 18, 22) that run axially to the shank end and coupling gibs (19, 20, 23) on the tool holder (10) that engage in said grooves, and also an axial locking feature comprising a depression (21) in the tool shank (11) that runs axially and is closed toward the shank end and a locking body (16) in the tool holder (10) that engages in said depression, two of said couplings (17, 19 and 18, 20) being at least partially opposite one another. For the purpose of uniform torque loading of tool shank (11) and tool holder (10), the couplings located one behind the other on the shank circumference starting from the axial locking feature are positioned with their coupling flanks on a circumferential angle of >180.degree.,

摘要： A device on hand-held tool-driving machines for the coupling of pounding and/or drilling tools is proposed, comprising at least three couplings and one axial locking feature, which are uniformly distributed over the circumference of the tool shank (11) and seating hole (13) of a tool holder (10). The couplings comprise recesses (17, 19, 21) on the tool shank (11) running axially to the shank end and also projections (18, 20, 22) on the circumference of the seating hole (13) running axially and engaging with the recesses. In order to avoid thrust-like overloads, it is proposed that the coupling (21, 22) in the circumferential area opposite the axial locking feature be designed/shaped such that its recess (21) and projection (22) on at least one longitudinal side run in chord-shaped fashion to the circumference of the tool shank (10) or the seating hole (13) of the tool holder (10) (FIG. 1).

摘要： The device for transferring torque to a tool member in a hand tool apparatus includes a plurality of catch grooves (23) and at least one elongated locking groove (25) spaced circumferentially from the catch grooves (23) provided in the tool shaft (11) of the tool member (12); a tool holder (10) having a tool receptacle (16) provided with a receptacle cavity (17) for the tool member (12) and having at least two axially extending catch elements (24) projecting inwardly into the receptacle cavity (17) so as to be engageable with the catch grooves (25) and at least one lock element (19) guided in a radial recess (18) provided in the tool receptacle (16) spaced circumferentially from the catch elements (24) so as to be radially movable outwardly against a spring force and engageable in the at least one locking groove (25) so as to limit axial motion of the tool member (12). To strengthen the torque transfer device for transferring torque to the tool member the at least one locking groove (25) in the tool shaft (11) includes a front portion (34) and a rear portion (33) and the front portion is deeper than the rear portion so that in a working position of the tool member (12) the at least one lock element (19) is located in the front portion of the at least one locking groove (25) and protrudes more deeply into the tool shaft (11) than in an idle position of the tool member (12) in which the at least one lock element (19) is located in the rear portion of the at least one locking groove (25).
