The fixing sleeve 450 is used to connect and fix the connecting sleeve 410 to the upper tube 211, and at the same time, it can strengthen the structural strength of the connection of the upper tube 211; the design of the first flange 213 can strengthen the structural strength of the upper tube 211, that is, it can strengthen the strength of the connection between the upper tube 211 and the lower tube 212. At the same time, the first flange 213 is used to fix the upper tube 211 and the connecting sleeve 410. The upper and lower surfaces of the first flange 213 are respectively attached to the connecting sleeve 410 and the fixing sleeve 450, that is, the first flange 213 is held by the connecting sleeve 410 and the fixing sleeve 450, so that the upper tube 211 and the connecting sleeve 410 are relatively fixed; The design of the two sealing elements 460 ensures the seal between the first flange 213 and the connecting sleeve 410, preventing water leakage between them. The design of the second flange 214 can strengthen the structural strength of the lower pipe 212, that is, strengthen the connection between the upper pipe 211 and the lower pipe 212. The maximum diameter of the second flange 214 is greater than the minimum diameter of the connecting sleeve 410, so that the downward movement of the lower pipe 212 will be limited by the connecting sleeve 410, preventing the lower pipe 212 from coming off. At the same time, the maximum diameter of the second flange 214 is smaller than the pipe diameter of the upper pipe 211, ensuring reliable relative sliding between the upper pipe 211 and the lower pipe 212.

[0033] In this embodiment, both the first seal 440 and the second seal 460 are O-rings.
