The guide device comprises a bolt (5) which by means of a sleeve insert can be fastened rotatably to one end of a rod (21), which bolt is connected, sliding axially, to the front part of a guide sleeve (16') in such a way that a rotary movement of the guide sleeve (16') can be transmitted to the bolt (5). A spring (20) pushes the bolt (15) out of the guide sleeve (16'). At the rear end of the guide sleeve (16') an at least approximately bell-shaped flange ring (17) is provided, which delimits an inside space which is dimensioned such that the head (1) of the sleeve insert can be accommodated therein. |
