<p>The invention relates to a chuck with at least one jaw set guided in a radially displaceable manner in a chuck body (1) and consisting of a driving jaw (3) and a gripping jaw (4) which can be connected in a positive-locking manner at its rear side to a coupling piece (6) which is mounted in the driving jaw (3) in such a way as to be displaceable at right angles to the jaw guide (1a, 1b) formed in the chuck body (1) for the jaw set and can be disengaged from the gripping jaw (4) by an eccentric (7) rotatably mounted in the driving jaw (3). So that the coupling piece (6) can be reliably secured in its coupling position with few and robust components and in a positive-locking manner, the eccentric (7), engaging with its eccentric shaft (7c) in a transverse groove (6b) of the coupling piece (6), is mounted in such a way as to be axially displaceable between two end positions and is provided with a stop (10) which, in one end position of the eccentric (7), engages in the transverse groove (6b) of the coupling piece (6) located in the coupling position and retains the coupling piece (6) in the coupling position in a positive-locking manner. …<IMAGE>… </p> |
