The extension lines of the stopping edges 3 are perpendicular to each other.
[0026] As Figure 4 shown, the cutter mounting plate includes a second mounting plate 16, a second inclined plate 17, a second cutter groove plate 18 and an arc plate 19 that are connected in sequence. A second mounting hole 22 is provided on the second mounting plate 16. The second mounting plate is stacked on the first mounting plate. The second mounting hole 22 is coaxial with the first mounting hole and is fixedly arranged on the lower pressing handle through the same screw. A second cutter groove 23 for the cutter to pass through is provided on the second cutter groove plate 18. The side of the second cutter groove plate 18 is bent to form a cavity 7 for placing the cutter. A cutter limiting groove 24 is provided on the top plate of the cavity 7. Convex plates are provided on both sides of the top plate of the cavity. A notch matching the convex plate is provided at the upper end of the side wall of the lower pressing handle. A side plate is provided on the side of the cavity away from the arc plate. A screw hole 25 is provided on the side plate. A limiting screw is arranged in the screw hole.
