The outer surface of each fixing rod 6 is slidably connected to the inner wall of the corresponding limiting groove 4. Specifically, the fixing rod 6 fixed on the side surface of each connecting member 5 moves along the corresponding limiting groove 4, and at the same time, the connecting member 5 flips to achieve the effect of opening or closing the baffle 8.

[0025] In a preferred embodiment, the workbench 1 is internally rotatably connected to a worm 9, and a worm wheel 10 is meshed on the outer surface of the worm 9. The worm 9 rotates and drives the worm wheel 10 to rotate, providing the worm wheel 10 with the power source required for rotation. The interior of the worm wheel 10 is fixedly connected to a rotating rod 11, and the outer surface of the rotating rod 11 is rotatably connected to the interior of the workbench 1.

The outer surface of the movable rod 13 is slidably connected to the inner wall of the corresponding limiting groove 4, and the movement trajectory of the rotating plate 12 is limited by the movable rod 13. Specifically, the rotating plate 12 is driven to rotate by the rotating rod 11, and the rotating plate 12 drives the movable rod 13 to move along the limiting groove 4, so that the rotating plate 12 can move along a predetermined route.

[0027] In this embodiment, the outer surface of the movable rod 13 is rotatably connected with a rotating plate 2 14, and the movable rod 13 provides a supporting force for the rotating plate 2 14, so that the end of the rotating plate 2 14 connected to the movable rod 13 can move synchronously with the movable rod 13, and the end of the rotating plate 2 14 away from the movable rod 13 is rotatably connected to the outer surface of the connecting rod 7. Specifically, the rotating plate 2 14 is driven to move by the movable rod 13, and the movable rod 13 moves along the inner wall of the limiting groove 4. At the same time, the rotating plate 2 14 drives the connecting rod 7 to move, and makes one of the fixed rods 6 fixed on the side of the connecting member 5 enter the bifurcation of the limiting groove 4. When the movable rod 13 enters the bifurcation of the limiting groove 4, the connecting member 5 is affected by the connecting rod 7 to complete the flipping action, thereby opening the discharge port 2.
