In addition, two ends of the belt 400 are respectively fixed on the first fixing part 210 and the second fixing part 230 . The method of fixing the two ends of the belt 400 to the first fixing member 210 and the second fixing member 230 respectively is to set hooks at both ends of the belt 400 and set them on the first fixing member 210 and the second fixing member 230. The corresponding fixing slots allow the two ends of the strap 400 to be locked in the fixing slots of the first fixing part 210 and the second fixing part 230 .

In summary, compared with the prior art, the combined box of the present invention is composed of a first U-shaped piece, a second U-shaped piece, a bottom plate, two side plates and a top cover, wherein the bottom plate, The side panels and the top cover can be replaced according to the size of the board, and the first U-shaped piece and the second U-shaped piece can be used for board packaging of various sizes. In other words, since part of the box body components are shared, the cost of mold opening and the cost of materials for manufacturing a new size shipping box can be reduced. And because the present invention is a combined box, if a certain box component is damaged, the damaged component can be replaced independently, avoiding the waste of raw materials and costs caused by scrapping the entire box.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
