Each plughole (3) is used for one of the two chain links. The insertion opening (4) and the two plugholes are all used for insertion of the chain links. The main connecting rod further comprises a lock component (5) can goes through the basal body (2), be connected in the insertion inlet and blocks the insertion inlet (4) in a working state (B). The lock component (5) is held in the basal body (2) through a form lock connecting member (6) in a working state. The main connecting rod designed in such a way enables easy assembly of the chain links. |
