A rotating sleeve 10 is rotatably sleeved on the outer ring of the rotating shaft, and a multi-function plate 11 is fixedly installed on one end of the rotating sleeve 10.
[0023] See also Figure 1-Figure 6The multifunctional plate 11 comprises a first concave plate 111, a groove is provided on the top of the first concave plate 111, so that the water on the top can be concentrated to the middle part to prevent the water on the top of the first concave plate 111 from flowing out from both sides. The first concave plate 111 is internally slidably sleeved with a first telescopic plate 112, and the first telescopic plate 112 is internally slidably sleeved with a second telescopic plate 113.
