Abstract

PURPOSE: To facilitate the manufacture of a driving key, and also to smoothly move the driving key in the radial direction by making a cylindrical shape of the outlines of the driving key. CONSTITUTION: By pulling an adjusting sleeve 9 rearward against the force of a compression spring 10, the adjusting sleeve 9 is partially turned in the counterclockwise direction around the longitudinal axis interlocking with the control groove 2c of a guide tube 2 and a stopper screw 12, to position the retreating recess 9c of the inside surface of the driving sleeve 9 in the region of a cylindrical drawing key 8. As a result, the driving key 8 is made to be movable outward in the radial direction. Further, the driving sleeve 9 is turned to position another retreating recess 9b in the region of a lock-stopping element 7, so that the lock-stopping element 7 is made to be movable outward in the radial direction. The insertion end part 6 inserted in this state into the free end of the guide tube 2 becomes free, and can be drawn out from the guide tube 2.
