[0035] Working principle: When in use, the staff holds the connecting ring 10 and aligns the fixed tube 14 and the connecting tube 16, and aligns the clamping block 2 13 with the gap between the multiple clamping rings 8, and then pushes the connecting ring 10 to insert the connecting tube 16 into the interior of the fixed tube 14 to complete the connection. At this time, the clamping block 2 13 passes through the gaps between the multiple clamping rings 8 and enters the same plane as the clamping block 19, and then rotates the connecting ring 10 to make the clamping block 2 13 contact with the clamping block 9, and the left side of the clamping ring 8 and the right side of the clamping block 2 13 fit together. The setting of the clamping block 9 will prevent the clamping block 2 13 from continuing to rotate so that the clamping block 2 13 reaches the maximum rotation distance. The setting of the clamping ring 8 is used to block the position of the clamping block 2 13 to prevent the connecting tube 16 from falling off the inner wall of the fixed tube 14. At the same time, the clamping ring 17 and the clamping ring 2 11 are in a fitted state to facilitate the connection assembly to fix the connecting tube 16.

[0036] When the connecting tube 16 is inserted into the interior of the fixed tube 14 to complete the connection, the right end of the fixed tube 14 passes through the central hollow of the connecting ring 10 and the clamping ring 11 and is inserted into the annular groove between the sleeve 17 and the connecting tube 16, so that the clamping sheet 22 is deformed, and then the clamping sheet 22 is pressed against the outer wall of the fixed tube 14. The clamping sheet 22 has a function similar to a barb. When the connecting tube 16 is separated from the inner wall of the fixed tube 14, it can grasp the fixed tube 14, thereby increasing the difficulty of separation of the connecting tube 16 and the fixed tube 14, thereby improving the connection stability of the connecting assembly. At the same time, the sealing ring 15 on the right side of the fixed tube 14 will squeeze the sealing ring 20, and then the sealing ring 20 squeezes the spring washer 19 to deform the spring washer 19. The deformation of the spring washer 19 in turn applies an elastic force to the sealing ring 20 in the direction close to the sealing ring 15, so that the sealing ring 15 and the sealing ring 20 are tightly fitted, thereby enhancing the sealing performance.
