The sealing groove 3 is annular in structure and the center of the circle and the center of the water pipe body 1 are located on the same center line, a sealing ring 6 is sleeved on the side of the second flange 5 away from the middle of the water pipe body 1, a sealing strip 7 and the sealing ring 6 are integrally formed, and the sealing strip 7 close to the water pipe body 1 is clamped in the sealing groove 3 on the second flange 5, and the sealing ring 6 are fixedly connected with sealing strips 7 on both sides, and the front and rear sides of the second flange 5 close to the middle of the water pipe body 1 are fixedly connected with positioning shafts 12. The other end of the water pipe body 1 is sleeved on the outside and slidably connected with a slip ring 8. The slip ring 8 is sleeved and slidably connected on the two positioning shafts 12. The slip ring 8 is fixedly connected with a collar 9 on the side away from the middle of the water pipe body 1. The collar 9 is sleeved on the outside of the second flange 5 and the sealing ring 6. The slip ring 8 is fixedly connected with a fixing ring 10 on the side close to the middle of the water pipe body 1. The fixing ring 10 is sleeved and slidably connected to one side of the water pipe body 1. A groove 11 is provided on the circumferential outer wall of the side where the fixing ring 10 is connected to the slip ring 8, which is used to pull the slip ring 8 when in use, driving the collar 9 to slide on the second flange 5.
