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