A round block 10 is rotatably connected to the outer wall of the round rod 9. Two groups of connecting rods 11 are fixedly installed on the side wall of the round block 10, and the other ends of the two groups of connecting rods 11 are respectively An annular plate 16 and an annular plate 2 13 are fixedly installed, and the annular plate 16 is located between the cylinder 1 and the cylinder 2 2. Several groups of limiting grooves 19 are evenly opened on the top of the annular plate 16 and the annular plate 2 13. The inner walls of several groups of the limiting grooves 19 are plugged and connected to the limiting blocks 16. Filter plates 17 are fixedly installed between several groups of the limiting blocks 16. The outer walls of the annular plate 16 and the annular plate 2 13 are rotatably connected to the annular plate 3 14. Several groups of baffles 15 are fixedly installed on the top of the two groups of the annular plates 3 14. Several groups of the baffles 15 are in contact with the top of the limiting blocks 16. The round rod 9 and the round block 10 are connected to the limiting assembly 12.

[0024] The limiting assembly 12 includes a handle 121, a limiting hole 122, a limiting plate 123, a spring 124, a limiting rod 125 and a rectangular plate 126. The rectangular plate 126 is fixedly connected to the lower end side wall of the round rod 9, and the limiting hole 122 is opened at the bottom of the round block 10.

[0025] The limiting rod 125 is slidably connected to the rectangular plate 126, the handle 121 is fixedly connected to the bottom of the limiting rod 125, the limiting plate 123 is fixedly connected to the outer wall of the upper end of the limiting rod 125, and the top of the limiting plate 123 is in contact with the bottom of the round block 10.
