A collection box 2 is fixed to an outer wall of one side of the workbench 1 by bolts. A U-shaped plate 3 is fixed to the outer wall of the top of the workbench 1 by bolts. A cutting assembly is arranged on the top of the U-shaped plate 3. Two fixing blocks 18 are fixed to the upper surface of the workbench 1 by bolts. A round rod 19 is rotatably connected between the two fixing blocks 18. A placing rack 6 is arranged on the upper surface of the workbench 1, and the placing rack 6 is fixed to the round rod 19. A plurality of supporting blocks 9 are fixed to the bottom of the placing rack 6 by bolts. The supporting blocks 9 can support the placing rack 6, and the supporting blocks 9 are in contact with the upper surface of the workbench 1. A plurality of through slots 8 are arranged inside the placing rack 6. A large piece of waste circuit board is placed on the upper surface of the placing rack 6. The cutting assembly is started so that the cutting assembly cuts the waste circuit board through the through slots 8 to divide it into small pieces.
