摘要

Drill chuck comprises a wedge-like tensioning ring (9) rotating about the chuck body (1) to drive a threaded ring (3). A wedge piece (10) is hinged on the inner side of the tensioning ring using a spring element (12) which pre-tensions the wedge piece. The wedge piece has an inclined wedge surface for blocking the tensioning surface of the chuck body by friction. A control sleeve is connected to an outer sleeve (5) and drives the tensioning ring. Preferred Features: An adjusting jaw (83) and a drive jaw (81) are arranged on the control sleeve. A drive channel is arranged on the tensioning ring for interacting with the drive jaw so that the tensioning ring is rotated.
