Abstract:
A tool holder for coupling of rotating and striking tools with hand power tools, comprising a coupling sleeve; a drive member connectable to a hand power tool and transmitting a drive movement, said coupling sleeve being connected with said drive member; a tool shaft provided with groove-shaped locking pockets which are closed at both sides in an axial direction, said coupling sleeve being connected with said tool shaft; elongated locking bodies which are oriented axis-parallel and engage in said locking pockets, said coupling sleeve having a longitudinal passage in which each of said locking bodies are axially displaceable and held radially movable; a displacement sleeve which surrounds said coupling sleeve with said locking bodies and is spring-loaded in an axial direction, said displacement sleeve having an inner blocking surface which blocks a radial movement of said locking bodies, each of said locking bodies has a construction which is saddle-shaped in a longitudinal section and has two humps which have an arcuate cross-section, are spaced from one another and abut against said blocking surface; a long, shaped body which is arranged at a side facing away from said humps and has a region engaging in said locking pocket and a cross-section form-lockingly corresponding to a cross-section of said locking pockets, said blocking surface of said displacement sleeve being provided with a ring groove which allows insertion of one of said humps and has a groove depth which is greater than a radial depth of said locking pockets.
