摘要

The instrument (W) has an expandable spiral spring body (17,22), a handle (1) provided at the instrument for an extension element (4), rotating handles (5,10) in connection with a spiral spring body-rotary pipe element (12,7), rotatable relative to the positioning element. A rotating locking device (R) is connected between the rotating handle (5,10) and the spiral spring body-rotary pipe element. The instant varying rotating force impulse is generated during a rotation under a torque produced by the rotating handle at spiral spring body-rotary pipe element.
