The sealing ring can penetrate through the annular groove to seal the annular sealing air bag, so that the annular sealing air bag deforms to connect the connecting pipe head and the inlet of the central hole together in a sealing mode. The sealing ring is provided with a plurality of (specifically 2) annular sealing teeth 974 which are sequentially sleeved together. The annular sealing tooth extends in the circumferential direction of the internally threaded pipe section. The end of the externally threaded pipe section remote from the connector head is connected to the end of the internally and externally threaded pipe section adjacent to the connector head by an automatic assembly and disassembly mechanism 98.

During this process, the first pin extension spring 983 and the second pin extension spring 987 are energized. Further rotation of connector head 99 until the male threaded pipe section is fully inserted into the female threaded pipe section causes seal assembly 97 to sealingly connect connector head 99 and the central bore. The specific sealing process of the sealing assembly is as follows: the sealing ring 973 is inserted into the groove 971 to seal the annular sealing bladder 972, such that the annular sealing bladder deforms to seal. The annular sealing air bag and the annular groove are sealed by being bonded together through glue. Make the contact surface between sealing ring and the sealing washer be the curved surface of turn back structure under the effect of annular seal tooth 974 to play the effect that improves sealed effect.
