In the locked state, the tapered head of the plug 2231 abuts against the tapered hole of the recess 122, and the plug 2231 overlaps the center line of the recess 122, so that the link 11 does not rotate even when a large external force is applied. If the plug 2231 and the center line of the recess 122 have a certain angle when the connecting rod is inserted into the second socket 212, similar to the principle of the first embodiment, the connector 223 of the second embodiment can also finely adjust the installation angle of the connecting rod 11, during the inward insertion of the connector 223, the plug 2231 will first contact with one side of the recess 122 and continue to be inserted into the connector 223, the plug 2231 exerts a force on the contact surface of the recess 122, so that the connecting rod 11 rotates until the plug 2231 and the center line of the recess 122 coincide, and then continues to be inserted into the connector 223, the plug 2231 and the recess 122 completely abut against the connecting rod 11, and the connector 223 tightly abuts against the connecting rod 11.
