The shape of the corner protectors can be right angle, rounded, U-shaped, L-shaped, or any structural form that can achieve column support.

[0054] In this embodiment, the slot can be a groove structure, an embedding structure, a clamping structure, or any structure capable of limiting the position of the accessory box. The slot can be located on the upper support, lower support, or the side wall of the support component, as long as it can stably fix the accessory box, it falls within the protection scope of this utility model. The number of slots is not limited to one; two or more can be provided as needed, or a continuous slot structure can be used, without affecting the protection scope of this utility model.

[0055] In this embodiment, the accessory box material is not limited to kraft paper; it can be made of PP, PVC, PET, cardboard, or other materials with sufficient rigidity. The accessory box can be square, rectangular, rounded, or other structural forms suitable for packaging. The accessory box may contain partitions, cushioning foam, or other accessory positioning structures, all of which are equivalent modifications.

[0056] The packaging structure 1 in this application has embedded grooves on the edges of the upper and lower supports to fix the independent kraft paper boxes for accessories, requiring no additional space and preventing accessories from squeezing the main unit 22; four cardboard corner protectors form an independent column-type support frame, transferring the external stacking force to the ground and not directly acting on the main unit 22; the upper and lower supports clamp and position the main unit 22, and the stability can still be guaranteed without large pieces of foam on the sides, reducing the amount of material used; the multi-component synergy improves the drop resistance, stacking performance and structural stability.
