Figure 1 As shown, at least two support rods 11 are arranged around the circumference of the ring wall of the top pipe 10. There are multiple middle pipes 20, and a water inlet hole 21 is provided on the ring wall of any middle pipe 20. A water outlet hole 31 is provided on the ring wall of the bottom tube 30. The top pipe 10, multiple middle pipes 20, and the bottom tube 30 are arranged in sequence from top to bottom. The inner diameters of the top pipe 10, multiple middle pipes 20, and the bottom tube 30 are consistent, and the outer diameters of the top pipe 10, multiple middle pipes 20, and the bottom tube 30 are consistent. Figure 3 As shown, the open end surface of the bottom tube 30 and one end of the plurality of middle tubes 20 are coaxially fixed with an annular protrusion 40, and the open end surface of the bottom tube 30 and one end of the plurality of middle tubes 20 are circumferentially arranged with a plurality of hooks 41. Figure 2 As shown, an annular groove 50 is provided at one end of the top pipe 10 and the other end of the plurality of middle pipes 20, and a plurality of plug holes 51 are arranged circumferentially at one end of the top pipe 10 and the other end of the plurality of middle pipes 20. After installation, the top pipe 10, the plurality of middle pipes 20 and the bottom tube 30 are plugged in sequence, and the annular protrusion 40 located on the bottom tube 30 or the middle pipe 20 can be inserted into the annular groove 50 of the adjacent middle pipe 20 or top pipe 10, and the hook 41 is inserted into the adjacent plug hole 51.
