[0007] Preferably, one end of the spring is fixedly connected with the pressing plate, and the other end of the spring is fixedly connected with the connecting plate. Through the setting of the spring, the elastic force can be applied to the pressing plate.

[0008] Preferably, a limiting block is fixedly connected to the top of the guide rod, and the limiting block is fixedly connected with the connecting plate. Through the setting of the limiting block, the guide rod is limited.

[0009] Preferably, the positioning mechanism includes two sliders slidably connected inside the support base. A movable block is fixedly connected to the bottom of each slider, and a clamping strip is fixedly connected to the top of each slider, with the clamping strip slidably connected to the support base.

[0010] Preferably, the end of the bidirectional screw is fixedly connected to a turntable, and a rotating rod is fixedly connected to the surface of the turntable. The turntable and rotating rod facilitate the rotation of the bidirectional screw.

[0011] Preferably, a support block is fixedly connected to the bottom of the support base, and the support block is connected to the bidirectional screw via a bearing. The support block provides support for the bidirectional screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a positioning mechanism on the support base. By rotating the bidirectional screw through the turntable and the rotating rod, the distance between the two moving blocks can be adjusted, thereby controlling the movement of the clamping strips above them towards and away from each other. This provides a positioning function for cutting cardboard of different widths, thus ensuring the stability of the cutting.

[0014] 2. This utility model provides multiple sliding rods that slide relative to the connecting plate used to fix the cutter. One end of the sliding rod is equipped with a pressure plate, and the other end is equipped with a limiting block. A spring is also provided on the outside of the sliding rod. In this way, when the cutter cuts the cardboard, the pressure plate can contact the cardboard before the cutter and press down on the cut, thus ensuring a smooth cut. Attached Figure Description
