     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       FIG. 1  is a structural schematic drawing of a preferred embodiment of the assembled packing case of the present invention, and  FIG. 2  is an explosive view of the assembled packing case of this embodiment. In this embodiment, the assembled packing case comprises a bottom component  100  and corner components  200  that embedded to the corner of the bottom component  100 . Limiting holes are set at the embedding positions of the bottom component  100  and the corner components  200 , and the assembled packing case further comprises fasteners  300  that insert into the limiting holes, when the fasteners  300  are inserted, the relative position between the bottom component  100  and the corner components  200  will be limited. The underside of the bottom component  100  is criss-cross, and the shape of the corner components  200  is consistent with the shape of the four corners of the corner component  200 , a cuboid case body with a hold space will be formed and various objects can be placed when the bottom component  100  and corner components  200  are assembled together. Herein, the criss-cross underside means the underside is a crossing intersecting structure. 
     The assembled packing case of this embodiment is particularly suitable for packing and transporting clintheriform fragile objects such as glass plates, case body barricades  400  are set on the bottom component  100  and corner barricades  500  are set on the corner components  200 . The hold space, which is formed by the case body barricades  400  and the corner barricades  500 , is as large as the glass plate that to be placed, therefore the glass plate will not move freely in the packing case, so the glass plate won&#39;t be damaged. 
     In order to further protect the glass plate, gaskets are stuck on the case body barricades  400  and the corner barricades  500 . Usually, the gaskets are made from plastic materials with excellent cushioning performance, for example, EPP, expandable polyethylene (expandable polyethylene, EPE), polystyrene (expanded polystyrene, EPS), etc. 
     As shown in  FIG. 2 , the bottom component  100  in this embodiment is hollow. The bottom component  100  with hollow structure can reduce the contact area between the bottom component  100  and the glass plates when the glass plates placed into the packing case, so it can avoid scuffing of the glass plate and reduce the overall weight of the packing case. 
     In this embodiment, the case body barricades  400  and corner barricades  500  can be embedded on the bottom component  100  and corner components  200 . The case body barricades  400  and corner barricades  500  can also be integrated with the bottom component  100  and corner components  200 . As shown in  FIG. 1  and  FIG. 2 , when embedded on the bottom component  100  and corner components  200 , slots need to be set on the bottom component  100  and corner components  200 . In the present invention, the embedding way is preferred: case body barricades  400  and corner barricades  500  with different sizes can be replaced for packing glass plates with different sizes, so as to arrange the glass plates immovably in the assembled packing case. 
     The way that the bottom component  100  and corner components  200  are assembled into a packing case will be detailed in the following description with reference to  FIG. 1  to  FIG. 3 . At the side of the assembled packing case, the bottom component  100  and corner components  200  are set as mortise and tenon structures at the embedding positions between the bottom component and the corner, so the tenons of the bottom component  100  could be embedded into the mortises of the corner component  200  (it is corresponding that the tenons of the corner component  200  could be embedded into the mortises of the bottom component  100 ). Limiting holes are set at the embedding position of the bottom component  100  and the corner components  200 , that is, a half of the limiting hole is set on the bottom component  100  and a half of the limiting hole is set on the corner component  200 . The complete limiting holes will be formed when the bottom component  100  and the corner component  200  are assembled. Then a fastener  300  is inserted into the limiting hole, as shown in  FIG. 3 . The number of the mortises and tenons is not limited in the present invention. For example, there is one tenon and one mortise on the bottom component  100  and the corner component  200  respectively, as long as the relative displacement between the bottom component  100  and corner components  200  on the vertical direction is limited by the mortise and tenon. 
     As shown in lateral view of  FIG. 3 , the relative displacement between the bottom component  100  and corner components  200  on the vertical direction is impossible because of the interaction of the mortise and tenon. On the horizontal direction, the relative displacement between the bottom component  100  and corner components  200  is impossible because of the embedding fasteners. In the direction perpendicular to the paper, the relative displacement will be restricted by another fastener. So, every corner component  200  will be fastened to the bottom component  100  by two fasteners  300  without thread, riveting, nor welding. 
     As the whole assembled packing case is formed by embedding corner components  200  to bottom component  100 , we can produce bottom components  100  with different size, and can replace the bottom component for packing objects with different size. Thereby, the versatility of the assembled packing case will be improved. 
     The shape of fastener  300  is not limited in the present invention. For example, the fastener shown in  FIG. 2  and  FIG. 3  is a square column with a dome, and it can also be replaced by other shapes, as long as it can limit the bottom component  100  and corner component  200 . 
     The present invention will further be explained how to assemble liquid crystal panel with reference to  FIG. 4 . Usually, the liquid crystal panel  700  is a rectangular liquid crystal cell with PCB extending on one side. When we transport and preserve the liquid crystal panel, we should make sure that the liquid crystal cell will not be damaged due to collision and the PCB will not be folded. A scaleboard  110  is embedded above the hollow-out bottom component  100 , and the underside shape of the scaleboard  110  matches with the underside shape of the bottom component  100 . Stop blocks  111  are arranged on the scaleboard  110 , and the stop blocks  111  are integrated with the scaleboard  110  to limit the position of the PCB of the Liquid crystal panel  700  to prevent PCB folded. The position of the stop blocks  111  can be selected according to size of the LED panel. In this embodiment, the scaleboard  110  can pack two same Liquid crystal panels  700  with small surface at the same time. When we need to pack and transport larger Liquid crystal panel, we can replace it with a scaleboard  110  which is provided with appropriate stop block  111 , so that the same one assembled packing case can fit the Liquid crystal panels with various sizes, and the versatility of the assembled packing case will be improved and the cost will be reduced. 
     A bottom component  100  with half-baked hold space will be formed after the scaleboard  110  embedded above the hollow-out bottom component  100  and packing case barricade  400  embedded in the bottom component  100 . Then a complete rectangle packing case will be formed when corner components  200  embedded to the four corners of the bottom component  100 . At last, insert the fasteners  300  to the limiting holes to make sure no relative displacement will occur between the corner components  200  and bottom component  100 . At this time, the hold space will be formed which matches with the Liquid crystal panel  700 . After the Liquid crystal panel  700  placed in the assembled packing case, the Liquid crystal panel  700  is immovable and its PCB board won&#39;t be folded, so the Liquid crystal panel  700  will be protected during transportation. 
     Aiming at size of the Liquid crystal panel, position of the PCB board and demand of packaging and transporting, we can combine different bottom components  100 , scaleboards  110  and corner components  200 , so the applicability of the assembled packing case will be improved.
