The right joint 2 is fixedly sleeved with a fixed ring 4 at one end located on the right side of the left joint 1, and a movable ring 5 is slidably sleeved on the outer surface of the right joint 2 and located on the right side of the fixed ring 4. The front and back sides of the movable ring 5 are fixedly connected with a control rod 18, and the shape of the control rod 18 is U-shaped. The movable ring 5 is connected to the fixed ring 4 through the airbag 7. The right inner wall of the annular groove 6 is provided with a A curved hole 8 is provided. When the movable ring 5 approaches the fixed ring 4 and squeezes the airbag 7, the internal gas can be pushed into the expansion ring bag 3 through the curved hole 8, so that the expansion ring bag 3 expands after being filled with gas to seal the gap between the inner wall of the left joint 1 and the outer surface of the right joint 2. The right end of the curved hole 8 is located between the movable ring 5 and the fixed ring 4. A spring 16 is provided on the inner side of the airbag 7. The two ends of the spring 16 are fixedly connected to the movable ring 5 and the fixed ring 4 respectively. The spring 16 has a tendency to push the movable ring 5 away from the fixed ring 4.

[0028] The upper and lower surfaces of the movable ring 5 are fixedly connected with card plates 9, and the sides of the two card plates 9 that are away from each other are meshed with card blocks 11. The sides of the two card blocks 11 that are away from each other are provided with movable blocks 10. The card blocks 11 are connected to the adjacent movable blocks 10 through telescopic rods 12. The telescopic rods 12 have a tendency to push the card blocks 11 close to the left joint 1.

The expansion ring bag 3 is in close contact with the inner wall of the left joint 1 through expansion, and the gap at the connection between the left joint 1 and the right joint 2 is blocked, and the clamping plate 9 follows the movable ring 5. Synchronous movement, when the card plate 9 moves to the left relative to the card block 11, the card plate 9 continuously applies thrust to the inclined surface of the right-angled triangle of the card block 11, so that the telescopic rod 12 is continuously extended and retracted. The vertical surface of the right-angled triangle of the card block 11 ensures that the movable ring 5 will not be reset away from the fixed ring 4, and ensures that the gas in the airbag 7 is stably filled into the expansion ring bag 3. When the left joint 1 needs to be separated from the right joint 2, the card block 11 is pushed to move back and forth and misalign with the card plate 9. The movable ring 5 is pushed away from the fixed ring 4 by the spring 16, and the gas in the expansion ring bag 3 is again drawn into the airbag 7, pulling the right joint 2 away from the left joint 1 to separate.
