摘要

The stud is manoeuvrable by a ring cut inclinedly on its one side by rotation around the stick. The stick comprises a hand grip (1), a tube (2) and a ferrule (10). In the tube is a rod (3) which at its one end is provided with a pin (9). In the tube is a track for the pin. The rod (3) at its other end supports against a stud (4) and on the stud is fixed a guide (6). The stud is held pressed against the rod by a spring (5) which in turn supports against a fixed guide (7). The rod can be moved forwards and backwards in the tube with the aid of an inclinedly cut ring (8) which is rotated around the tube (2). The ring is provided with stop positions for both an inserted and a withdrawn stud.
