The cutting groove 11 is arranged in cooperation with the cutting knife 5. During work, the electric cylinder 3 is started, so that the mounting plate 4 drives the cutting knife 5 to descend to quickly cut the strip on the cutting table 10. When the mounting plate 4 descends, it can drive the telescopic rod 7 to descend, and then drive the pressing plate 9 to descend, so that the pressing plate 9 presses the strip laid on the surface of the cutting table 10. Since both sides of the cutting table 10 are arranged as inclined planes, the pressing plate 9 will slide to both sides, which can press the strip to both sides, avoid the movement of the strip and cause cutting misalignment, with high accuracy, and the pressing plate 9 has the effect of flattening the strip to avoid the movement or wrinkling of the strip.
