During assembly, at least one support block a413 and a support block c are inserted along the opening a409 provided on the panel a404 and the panel b405 to achieve preliminary horizontal limit of the support block a413. The elastic support block 415 is inserted into the fixing hole 410 provided on the panel a404 and the panel b405 to achieve preliminary limit of the elastic support block 415. Subsequently, the panels a404, b405 and c406 are stacked in sequence, and the stacked panels a404, b405 and c406 are placed in the outer frame 402. At this time, the inner side panels a407 and b408 are both in contact with the inner wall of the outer frame 402, and the support plate c416 is located in the insertion hole of the support plate a. At this time, the support block b414 can be staggered and plugged with the support block a413 located above the panel a404. Then assemble the front corner lining 200. During assembly, the first plate d204 is bent 90 degrees along the crease line toward the first plate c203. Then, the first plate e205 is bent along the crease line toward the first plate d204. To ensure that the overall fold is L-shaped, a reinforcement plate can be set on the first plate e205. The reinforcement plate is connected to the first plate c203. To improve the supporting effect of the front corner lining 200 on the product, a support panel 211 can be added. The support panel 211 is placed On the No. 1 plate c203, and the upper and lower contour lines are aligned, and then the No. 1 plate a201 and the No. 1 plate b202 are bent 90 degrees along the crease line toward the No. 1 plate c203. At this time, the No. 1 plate a201, the No. 1 plate b202, the No. 1 plate c203 and the No. 1 plate d204 completely wrap the support panel 211. Since the No. 1 plate f206 and the No. 1 plate g207 are provided with crease lines, and the crease lines connect the No. 1 plate f206 and the No. 1 plate g207, the No. 1 plate a201 and the No. 1 plate b202 are bent 90 degrees along the crease line toward the No. 1 plate c203. 7, when bending, the first plate f206 and the first plate g207 can be bent 90 degrees along the crease line in sequence to form a U shape, and parts of the first plate f206 and the first plate g207 are in contact with the surface of the first plate a201, wherein a support plate can be placed in the cavity formed after bending to improve the supporting capacity of the forefoot lining, the connecting plate a208 can be bent to connect with the first plate f206 and the first plate g207 respectively, and the connecting plate b209 can be bent to connect with the first plate f206 and the first plate g207.
