The spring on the wall of the spring plate 42 will be compressed, and the limit block 44 will separate in the rectangular groove of the original adjustment edge 37 wall. At this time, pull the lower sieve plate 35 forward. The lower sieve plate 35 will drive the adjustment edge 37 to slide in the adjustment groove 33, and the expansion block 38 will slide in the expansion groove 34. When the lower sieve plate 35 moves, the position of the movable sieve hole 36 will also move, thereby adjusting the distance between the movable sieve hole 36 and the fixed sieve hole 32. After completion, the connecting rod 45 is loosened. At this time, the spring on the top of the spring plate 42 will push the spring plate 42 downward. The spring plate 42 drives the limit block 44 to enter the rectangular groove corresponding to the wall of the adjustment edge 37, thereby fixing the position of the lower screen plate 35.
