[0034] As shown in the figure, Figure 4 The connecting pipe 5 can adopt a through pipe structure and can pass through the connecting line 3. The connecting pipe 5 can be detachably connected with the sealing pipe 4. A connecting ring 51 is arranged at the bottom of the connecting pipe 5. The connecting ring 51 protrudes from the connecting pipe 5 along the radial direction of the connecting pipe 5. The connecting ring 51 is uniformly provided with through holes corresponding to the connecting columns 42. The connecting columns 42 can be inserted into the through holes of the connecting ring 51.
