[0010] It is further characterized by:

[0011] It also includes end side auxiliary positioning square rods, each of which has the same length as that of each frame, and each of which is arranged at the upper and bottom positions of the two end face areas of the box structure perpendicular to the second square tube, and alignment holes are arranged at the positions corresponding to the first positioning hole and the second positioning hole in the length direction of the corresponding end face of the auxiliary positioning square rod, and the protruding mounting part or the concave positioning part of the mounting connector corresponding to the frame assembly is placed in the alignment hole;

[0012] The entire box is not limited to a single-layer rectangular structure, a single-layer special-shaped structure, an N-layer cubic structure, or an N-layer special-shaped structure, where N is a natural number greater than or equal to 2;

[0013] The inner surface of the inner edge of the frame in the thickness direction facing the inner surface of the packaging box cavity is used to fix the corresponding edge of the central plate, and the first positioning hole and the second positioning hole are arranged on the outer side of the frame in the thickness direction relative to the central plate, which ensures that the installation of the connector is convenient and reliable during the assembly process;

[0014] The installation connector is specifically a bolt-nut combination structure or a spring pin structure;

[0015] When the mounting connector is a spring pin structure, it specifically includes a convex pin portion with a spring and a concave pin portion with a threaded positioning hole;

[0016] The enclosure connecting member comprises a bottom plate, a side connecting plate, and an upper side convex connecting rod.

The forklift inserts the pallet and transports the entire assembled packaging box through the forklift transfer space, and the square tube connecting piece is fixedly connected to two adjacent first square tubes or second light tubes arranged in the same straight line, so that the square tube connecting piece expands the first square tube and the second square tube in two dimensions according to requirements, and then the pallet can be arbitrarily expanded in two dimensions according to product specifications, and can be quickly packed according to the size of the products to be packaged as needed. The pallet area can be quickly expanded. The adjacent parallel independent unit panel assemblies can be spliced ​​on all four sides of the unit panel assembly by installing connecting parts, and with the assistance of the third positioning hole or the fourth positioning hole, the unit panel assembly can also be expanded in the vertical direction. It can quickly expand the three-dimensional surface area according to the size of the product to be packaged, so that the panel per unit area can be quickly adapted to product packaging of different specifications.
