The principle and the advantages of the scheme are as follows: 1) the movable plate is horizontally connected to the rack in a sliding mode and can slide relative to the rack, so that the action of sliding extrusion along the crease line is simulated when the crease position is manually extruded, the extrusion effect of the crease position is better, and the shaping is more stable;

2) the squeezing roller is rotatably connected to the movable plate, so that when the movable plate horizontally slides to squeeze the crease, the squeezing roller can roll relative to the paper, namely the squeezing roller can change sliding friction between the movable plate and the paper into rolling friction (namely static friction), thereby avoiding the technical problem that the paper is easy to damage due to overlarge friction force between the movable plate and the paper;

3) this scheme is equipped with the squeeze roll, and the upper surface of squeeze roll is higher than the upper surface of fly leaf, so the squeeze roll can follow the fly leaf and bulge out and extrude the crease part, has strengthened the extrusion effect.
