摘要

The locking mechanism (22) is in the head cover (14) of a cylinder tube (12). It includes a holder (32) in the cover, several balls (36) spaced out radially in the holder, and a displacement element (38), moving the balls by the return force of an elastic element (40). The balls engage in the groove of a locking pin, limiting its movement.
