[0010] The beneficial effects of the utility model are:

[0011] 1. The present invention pre-secures the edges of the sheet skin to a connecting plate, then places the sheet skin and connecting plate assembly onto the frame, and secures the connecting plate to the corresponding frame frame from the outside. This creates a combined, connected sheet skin with the connecting plate, significantly increasing its strength and preventing it from shaking during transport. More importantly, because the sheet skin is located inside the frame, forming an inner skin, it is safer to handle without risk of injury.

[0012] 2. The utility model makes it easier to rivet the connecting fixing plate and the thin plate skin, improves the riveting efficiency, reduces the production cost, and makes the riveting more convenient. Moreover, the appearance of the riveted thin plate skin is more beautiful.

[0013] 3. The utility model connects the connecting fixing plate to the corresponding frame on the frame from the outside of the frame by riveting, which makes the riveting of the connecting fixing plate and the frame more convenient, improves the riveting efficiency and reduces the production cost.

[0014] 4. The present invention reduces the material cost of the connecting and fixing plates by respectively providing protrusions corresponding to the corresponding frames of the skeleton on the first connecting fold and the second connecting fold, without having to raise the height of the first connecting fold and the second connecting fold as a whole.
