[0002] Chinese authorized publication number CN214357269U, with the authorization publication date of October 8, 2021, discloses a flat-shaped packaging carton for fragile items, including a box body and a box cover. The flat-expanded structure of the box body includes a bottom plate, with end plates connected to both the upper and lower sides of the bottom plate; side plates are connected to both the left and right ends of the bottom plate; the outer side of the side plate is connected to an inner side plate, and the outer side of the inner side plate is connected to a flap, with a communication groove provided on the inner side plate and the flap; the outer side of the end plate is connected to an inner end plate, and the outer side of the inner end plate is connected to an end plate flap; buffer pieces are connected to both sides of the inner side plate; the buffer pieces are provided with limit grooves; the bottom plate is provided with a folded-edge support plate, which is rectangular, with one side connected to the bottom plate; the folded-edge support plate bypasses a lock hole and is fixed to the bottom plate. The advantages of the utility model are that the horizontal periphery of the workpiece abuts against the limit grooves, and the up and down directions are restricted by the folded-edge support plate. Therefore, the positioning is firm and the filling material is omitted. The defect of this prior art is that when the product is placed in the box body and then covered, the top of the product is mainly supported by the folded-edge support plate, and when it is severely dropped, the product is very likely to flatten the folded-edge support plate and be damaged, and the surface of the product is also easily scratched by the folded-edge support plate. In view of this situation, it is urgent to improve. Summary of the Utility Model
