[0021] The effect achieved by the entire embodiment 1 is that, by setting the placement plate 2, the paper to be cut is stacked and placed on the placement plate 2, and by the operation of the two telescopic rods 4, the two clamping plates 5 can be driven to move toward each other, so that the two clamping plates 5 can be limited and clamped according to the width of the paper to avoid the phenomenon of accidental movement. After the limited clamping is good, the operation of the driving structure 6 drives the placement plate 2 and the paper placed on the top thereof to move, so that it moves to the lowering of the cutter 12, and by the operation of the hydraulic push rod 10, the cutter 12 is driven to descend to cut the paper, and the cutter 1 When the cutter 12 descends, the stabilizing plate 13 provided on its outer side will contact the paper in advance, so that it can press down the outer side of the paper where the cutter 12 cuts the paper to prevent the paper from being greatly deformed, and provide greater stability. When the bottom end of the stabilizing plate 13 contacts the paper, the connecting plate 11 will drive the fixing plates 16 fixed at both ends to continue to descend under the guidance of the connecting pillars 17, thereby driving the cutter 12 to descend and perform the cutting process.
