[0026] A driving assembly 4, wherein the driving assembly 4 is disposed on the body 1 and is movably connected to the movable jaw plate 3;

[0027] A screening plate 5, wherein the screening plate 5 is fixedly connected to the static jaw plate 2, and the screening plate 5 is slidably connected to the movable jaw plate 3.

[0028] In this embodiment, the static jaw plate 2 is fixedly connected with a screening plate 2 6, and the screening plate 2 6 is slidably connected with the movable jaw plate 3. The movable jaw plate 3 is provided with a residual circular annular groove 1 31 for matching the screening plate 1 5, and the movable jaw plate 3 is provided with a residual circular annular groove 2 32 for matching the screening plate 2 6. The material enters between the static jaw plate 2 and the movable jaw plate 3 through the feed port, and the driving component 4 drives the movable jaw plate 3 to swing back and forth on the body 1, and then cooperates with the static jaw plate 2 to crush the material. After the crushed material is screened by the screening plate 1 5, the smaller material falls on the screening plate 2 6. Similarly, after the crushed material on the screening plate 2 6 is screened by the screening plate 2 6, the smaller material passes through the screening plate 2 6, so that the graded crushing of the material is achieved, and the material size is uniform and the crushing effect is good.
