ABSTRACT:
The quick-change chuck is adapted to be fitted on a shank sleeve fitted is inserted to rotate therewith. A locking nut screws on the locking sleeve and a ball sleeve is carried by the shank sleeve. The ball sleeve has an annular extension piece with locking balls in an annular groove of the locking nut. A connector bush is axially displaceably held on the ball sleeve, is subject to the axial pressure of a spring, and has inner reception part and a substantially frusto-conically converging ramp face. A detent device automatically detains the connector bush in relation to the ball sleeve in its axial release position against self-effected dropping back into the locking position under the action of the spring, and on the introduction of the locking sleeve can be over-ridden with subsequent automatic axial displacement of the connector bush by means of the spring into its locking position.
