[0011] Preferably, the support plate has a bottom support plate on both sides.

[0012] Preferably, the bottom sleeve is internally fixedly connected with an internal support rib.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a limiting block, which is formed by combining multiple limiting blocks, the limiting block can be moved down when the punching component tilts during the punching and grooving process, thereby avoiding hard compression of the punching component, avoiding damage to the heavy-duty component and the limiting block, increasing the safety of use. By using multiple limiting blocks in combination, the bending of the limiting block due to uneven force can be avoided, ensuring the stability of use.

[0015] 2. In this utility model, the electric telescopic rod is used to adjust the position of the side frame. Together with the bottom card sleeve and the inner groove, it facilitates the replacement of the bearing plate, making it suitable for slotting different cartons. The extension sleeve guides the movement direction of the limiting block, making the sliding of the limiting block smoother. The side sliding rod and the side sliding groove limit the limiting block, preventing it from rotating and ensuring the positioning effect of the carton. The inner support rib is used to support the bottom card sleeve and increase its strength. Attached Figure Description
