[0007] Compared with the prior art, the utility model has the advantages that: by arranging the first punching device and the first pressing device on the base, the side of the luggage case side panel body placed on the contour positioning block can be punched, thereby punching out the first mounting hole on the side of the luggage case side panel body. This new punching die is not restricted by the special-shaped surface of the luggage case side panel body, and the whole set of structures is accurately positioned, simple and practical.

[0008] As an improvement of the utility model, the punching cylinder is threadedly connected to the base plate through a cylinder fixing block, and a guide block is provided at the front end of the punch to prevent the punch from shaking. The purpose of selecting this design: the punching cylinder is threadedly connected to the base plate through a cylinder fixing block, and the height of the punching cylinder can be easily adjusted to align with the mounting hole to be punched; a guide block is provided at the front end of the punch to prevent the punch from shaking, so as to punch out the mounting hole more accurately. On the other hand, since the length of the punch is relatively long, the provision of a guide block can also enhance the rigidity of the punch.

[0009] As an improvement of the utility model, the pressing cylinder is fixed to the base bottom plate through an ear plate. The purpose of selecting this design is that the pressing cylinder is matched with the punching cylinder to press the side panel of the luggage box and is fixed to the base bottom plate, and the two sets of devices will not interfere with each other.

[0010] As an improvement of the utility model, the rotation point of the piston rod and the rotating pressure block is the first rotation point, the rotation point of the hinge seat and the primary pressure rod is the second rotation point, and the rotation point of the hinge seat and the rotating pressure block is the third rotation point; from the horizontal direction, the height of the first rotation point is greater than the height of the second rotation point, and the height of the second rotation point is greater than the height of the third rotation point. The purpose of selecting this design: This structure allows the piston rod to press the primary pressure rod after it is extended, and the landing point of this pressing can change according to the change of the length of the rotating pressure block and the length of the piston rod, so as to achieve different clamping forces.

[0011] As an improvement of the utility model, a secondary pressure rod is fixed under the primary pressure rod. The purpose of selecting this design is that the secondary pressure rod can better match the shape of the side panel body of the luggage compartment, because the positions of the mounting holes on the side panel body of the luggage compartment are different, and the surrounding shapes and spatial structures of each mounting hole are also different. Sometimes the primary pressure rod cannot be pressed or pressed firmly, so the secondary pressure rod can make up for the defects of the primary pressure rod. BRIEF DESCRIPTION OF THE DRAWINGS
