The partition plate 302 divides the inner side of the ring block 301 into two honeycomb grooves 303. The first honeycomb core 200 and the second honeycomb core 400 are both in the honeycomb groove 303. The sizes of the first honeycomb core 200 and the second honeycomb core 400 match the honeycomb groove 303. By adopting a double-layer honeycomb core design, the thickness of the honeycomb core is reduced. Under the same honeycomb core material thickness, the overall strength is greatly improved and the impact resistance is significantly improved.

At this time, the insertion block 601 will be clamped in the groove 603 of the slot block 602, with high stability.

[0039] When the honeycomb panel packaging lining is subjected to a large impact force, the first honeycomb core 200 is partially impacted and partially deformed. When the impact force reaches the second support plate 300, the pressure relief will be distributed to avoid a large impact on the second honeycomb core 400. The second honeycomb core 400 will not be deformed, thereby achieving the purpose of enhancing the impact resistance.
