Two second fixing rods 11 are fixedly welded between the two first fixing rods 10. The two second fixing rods 11 are respectively provided on the front and rear sides of the roller cutter 8. Two mounting blocks 13 are provided on the second fixing rods 11. Two L-shaped connecting rods 12 are fixedly welded on the mounting blocks 13. The end of the L-shaped connecting rod 12 away from the mounting block 13 is fixedly welded to the top wall of the pressure foot 9. Movable seats 14 are fixedly welded on the two first fixing rods 10. The two movable seats 14 are slidably connected in the through slots opened on the two support plates 2.
[0021] Two fixed seats 15 are fixedly welded onto the support plate 2. The two fixed seats 15 are respectively set at the upper and lower ends of the through groove of the support plate 2. A guide post 16 is fixedly welded onto the two fixed seats 15 of one support plate 2. A screw 17 is rotatably installed on the two fixed seats 15 of the other support plate 2. A handwheel 18 is fixedly installed at the top of the screw 17. One movable seat 14 is slidably connected to the guide post 16 through an opening. The other movable seat 14 is threadedly connected to the screw 17 through an opening. When the screw 17 rotates, it can drive the movable seat 14 to rise and fall under the guidance of the guide post 16, thereby driving the four pressure feet 9 to adjust their height.
[0022] Two grooves 19 are provided on the opposite side wall of the two second fixing rods 11, and two through holes 20 are provided on the top wall of the second fixing rods 11.

[0025] Working principle: When in use, the screw 17 can be rotated by the handwheel 18. When the screw 17 rotates, it can drive the movable seat 14 to rise and fall under the guidance of the guide column 16. The two movable seats 14 can drive the four presser feet 9 to adjust their height through the cooperation of the first fixed rod 10 and the second fixed rod 11, which is convenient for pressing various cardboards of different thicknesses.
