<p>The clamping chuck (100) holds an auxiliary rotary tool (2) such as a screwdriver or a cutting tool. The inserted end (21) of the shaft (20) is held by the chuck (100), thus preventing relative rotation, and axial displacement may be blocked using a locking pin (150). When inserted into an eccentrically arranged rotary knob (130), the locking pin (150) may be snapped into a meshing groove (22) at the inserted end (21), fixing the auxiliary tool (2) in the chuck (100). The rotary knob (130) encases an eccentric journal (140) fixed rigidly to the upper end of the ratchet (110) and may be moved over about 60° between end positions. The chuck (100) is characterized by very secure holding of the auxiliary tool (2) and short overall length.</p> |
