[0026] The clamping assembly includes a conical clamping pin 87, which is movably arranged in a groove 86, and the groove 86 is arranged on one side of the annular clamping groove 81. The conical clamping pin 87 is clamped in a conical clamping groove 88, and the conical clamping groove 88 is arranged on the outer surface of the connecting head 12, which can position the connecting head 12.
[0027] A return spring 85 is arranged in the groove 86, and one end of the return spring 85 is connected to the conical clamping pin 87, which can automatically drive the conical clamping wire to perform a return movement.
[0028] Insert the connector 12 into the annular grooves 81 of the input interface 9 and the output interface 8 respectively. When the connector 12 contacts the conical pin 87, the connector 12 drives the conical pin 87 to move in the groove 86. The conical pin 87 compresses the return spring 85. After the connector 12 is connected to the connection end 82, the return spring 85, under the action of elastic force, snaps the conical pin 87 into the conical groove 88, and the conical pin 87 fixes the connector 12.
[0029] Furthermore, a guide block is provided on the conical bayonet 87 , and the guide block is movably provided in the guide groove, and the guide groove is provided in the groove 86 . The movement of the conical bayonet 87 drives the guide block to move in the guide groove, thereby improving the guiding property of the conical bayonet 87 when moving.
