The screw-on tube block 5 is screwed onto the lower end of the injection port tube 3, and the linkage block 2 is screwed onto the bottom of the injection port tube 3. The lower part of the tube block 5 is interconnected with the bucket plate 10 through the side block guide tube 6 and welded. The lower opening of the bucket plate 10 is welded with an injection tube 11. An air bladder 7 is clamped and bonded inside the side block guide tube 6, and an adhesive arc sleeve 8 is clamped and bonded to the outside of the air bladder 7. The two ends of the sleeve of the adhesive arc sleeve 8 are bonded to the spin-on tube block 5 and the side block guide tube 6 through adhesive guide heads 9. An air connecting tube 13 is integrally formed on one side of the air bladder 7, and the tube body of the air connecting tube 13 passes through the rigid connecting tube 12 welded to the side of the side block guide tube 6.

[0027] The side block conduit 6 has an embedded cavity 14 inside its tube, and an airbag 7 is inserted and bonded into the cavity 14.

[0028] By adopting the above technical solution, the cavity 14 inside the side block conduit 6 can accommodate the airbag 7 for bonding and fixation.

[0029] Among them, a support ring 15 is fixed in the body of the spin-on tube block 5, and a gasket 16 for supporting the injection port tube 3 is placed on the surface of the support ring 15.

[0030] By adopting the above technical solution, the spin-on tube block 5 uses a support ring 15 to support the gasket 16 inside, thereby increasing the sealing performance of the connection between the injection port tube 3 and the spin-on tube block 5.

[0031] Among them, a threaded cavity is provided in the rigid connecting pipe 12 on one side of the gas connecting pipe 13;

[0032] By adopting the above technical solution, the rigid connecting pipe 12 can be screwed onto an external controllable gas supply pipe through the threaded pipe cavity, thereby enabling the gas connecting pipe 13 to be connected to a controllable gas source through the rigid connecting pipe 12.

[0033] The adhesive guide 9 is fixed in the spin-on tube block 5 and the side block guide tube 6 by means of an arc-shaped block, and the outer surface of the adhesive guide 9 away from the adhesive arc sleeve 8 is an arc surface.
