Support bars 4 are connected to the four corners of the top of the first support frame 2, and the support bars 4 abut against the corresponding sides of the inner wall of the box body 1. A second support frame 3, supported on the top inner side of the box body 1, is connected between the tops of the four support bars 4. The first support frame 2, together with the four support bars 4 and the second support frame 3, can... The inner wall of the carton body 1 is supported to increase the structural strength of its corners. A support plate 6 is provided below the support shell 5. When the device falls, the support plate 6 will hit the ground first to provide a cushioning. Multiple support columns 7 are evenly connected to the top of the support plate 6. Support rods 8, which are glued to the bottom of the support shell 5, are movably inserted into the inner side of the support column 7. A first spring 9 is connected between the corresponding side of the support rod 8 and the support column 7. The multiple support rods 8 above the support plate 6 will move down relative to the support column 7 due to the pressure of the carton body 1. The first springs 9 on the inner side of the multiple support columns 7 can provide a secondary cushioning.

[0019] Specifically, each of the two support bars 4 on the left and right sides is connected to a connecting rod 10 on the opposite side, and a second spring 11 is connected between the two support bars 8 on the same side. When the left and right sides of the carton body 1 are subjected to external force impact, the two support bars 4 on the left and right sides will tend to move closer together.
