[0018] The metal plate conveyor belt 4 contacts the sliding ball 20 , and the sliding ball 20 is rotatably embedded in the four sides of the bottom end of the limit block 14 . The friction between the metal plate conveyor belt 4 and the limit block 14 is reduced by setting the sliding ball 20 .

[0019] Among them, the pointing block 15 is fixedly connected to the electric telescopic rod 18, and the electric telescopic rod 18 is fixedly connected to the upper end of the pressure plate 19. The pressure plate 19 contacts one side of the limit block 14. By setting the pressure plate 19 to contact the pointing block 15, it can be limited to the upper side of the plate, thereby making the cutting process more stable.

[0020] Among them, the pressure roller 23 is rotatably connected between two opposite sliders 22, the slider 22 is threadedly connected to the second screw 21, the second screw 21 is rotatably connected to the second groove, and the second groove is located on both sides of the connecting frame 2 away from each other.
