摘要

The coupling has a main body (1) or ball joint. It also has a setting lever (5) to connect the ball joint to a carrier. A bolt (4) consists of a central eccentric and two outer cylindrical sections. The end of the bolt is coupled via a thread to the lever, and acts with a locking element located in the lever, to block the system. A forked part (13) of the lever engages into a bore in the bolt and has a connected chain (15).
