ABSTRACT:
The clamp jaws radially adjustable by a drive member each comprise a jaw base guided in the chuck body and a mounted jaw member replacably attached with it as well as at least one connecting pin which is mounted pivotable about the pin axis in the jaw base. According to rotary position the attachment between the jaw base and the mounted jaw member is released or locked. At least one control rod guided longitudinally slidable in the jaw base is coupled with the connecting pins by gear teeth so that the motion of the control rods relative to the jaw base converts to a rotation of the connecting pin and vice versa. The feed of the control rods in the jaw base runs parallel to the feed of the jaw base in the chuck body. For the control rod a controlling member is provided by which the control rod is held fixed from motion relative to the chuck body. The jaw base is slidable for rotation of the connecting pins by its drive member with the control rods held fixed in position. Thus with the control rod held fixed the connecting pins are rotated under force by motion of the jaw base.
