The lock member 93 includes a sliding portion 931, a pushing portion 932 and a locking portion 933. The smooth sliding of the sliding portion 931 in the locking slide 92 ensures the overall stability and response speed of the lock member 93; the pushing portion 932 acts as a power source, and through the action of an external force (such as the pressing bar 91), it pushes the locking portion 933 to move precisely in the locking slide 911, so as to achieve a close fit or separation between the locking buckle 934 and the object connector. The locking buckle 934 is designed to automatically adjust the locking state according to the position: when it is located at the front end of the limit buckle 912, the locking buckle 934 firmly locks the object connector, effectively preventing accidental loosening due to vibration or external force; and when it moves to the rear end of the locking buckle, it automatically enters the unlocking state, which is convenient for quick separation of the connector and improves the efficiency of maintenance or replacement.
