摘要

Step-connecting device comprises a spring (9) located in a guide element (1) and acting on a leveling element (2) via a pressure pad (14) and a cone (15) and a connecting rod (18) and a pressure pad (17) of holding jaws (16). The holding jaws positioned between the pressure pads are brought into their closed or open position by the cone. A force-locking connection is formed between a lever (21) held eccentrically by a bolt (20) and the cone via an adapter (19) and the connecting rod. A chain (8) of specified length is fixed by a pin (12) at one end to the guide element and at the other end to the leveling element to prevent the leveling element from falling out. A holder (4) is fixed to the guide element by two holding clips (5). A threaded bushing (22) for an adjusting screw (23) is fixed on the holder to allow axial adjustment of the device.
