Wherein the wire body is sleeved with the first spring, one end of the first spring is fixedly connected with the connector, the other end of the first spring is fixedly connected with the fixing sleeve, the wire body is symmetrically sleeved with two sets of clamping blocks, sliding mechanisms are installed on the clamping blocks, and a locking mechanism is arranged between the two sets of clamping blocks. Through the arrangement of the first spring, when the connector is pulled and plugged, if the wire body is pulled, the fixing sleeve can be stressed to pull the first spring to deform, and the first spring can absorb and relieve the tensile force borne by the connecting positionof the connector and the wire body through the elastic deformation characteristic, so that the connecting position of the connector and the wire body is protected.
