<p>The coupling unit is designed as an overload coupling. The torque at which coupling is released, is predetermined by a torque adjuster (38). Its construction employs components of the locking and release mechanism (36), which include a manually-operated ring casing (16). This casing sets the maximum torque. It is adjusted along the tool longitudinal axis (18) by turning it about this axis. It runs on a thread (20) of the chuck (4) inner casing which surrounds the drive spindle.</p> |
