When limiting the sheet metal, the existing sheet metal limiting structure mainly uses the rotation of the threaded rod to press the sheet metal, and relies on the friction between the threaded rod and the sheet metal to limit the sheet metal. However, because the extrusion needs to be relatively tight, the threaded rod needs to be rotated a certain distance after contacting the surface of the sheet metal. At this time, a certain friction force is generated between the threaded rod and the surface of the sheet metal. When rotating, the threaded rod is likely to drive the sheet metal to rotate, causing the sheet metal to deviate from the original position and need to be repositioned, making the limiting process very troublesome.
