[0025] The reason for setting the rotating groove 9 is to enable the slider 13 to slide from the sliding groove 8 to the rotating groove 9 and rotate the feed pipe, so as to limit the height of the feed pipe 5. The unloading groove 11 is connected to the rotating groove 9 so that the feed pipe 5 can be disassembled when the feed pipe 5 rotates again. Embodiment 3

[0026] See also Figures 5 and 6 On the basis of the second embodiment, in order to fix the feed pipe 5 and the feed cover 3, a limiting groove 10 is provided on the surface of the feed pipe 5, and the limiting groove 10 is an annular groove.
