The expanded view of the inner frame 2 is shown in fig. 2, two folding grooves 5 are formed in the bottom plate 21, and two first four-corner corrugated columns 23, three first middle corrugated columns 24, three second middle corrugated columns 24 and two second four-corner corrugated columns 23 are sequentially arranged on the side plate 22 along the length direction. The interval between the stupefied post 23 crease in two adjacent first four corners is 70mm, and the interval between the stupefied post 24 crease in the middle of two adjacent first is 40mm, and the interval between the stupefied post 24 crease in the middle of two adjacent second is 40mm, and the interval between the stupefied post 23 crease in two adjacent second four corners is 70 mm.

Referring to fig. 2, the limiting plate 3 is disposed on one side of the four-corner prismatic column 23 close to the middle prismatic column 24, one side of the four-corner prismatic column 23 abuts against the inner side wall of the outer box 1, and the other side of the four-corner prismatic column 23 abuts against the limiting plate 3. Be equipped with spacing paper frame 4 in the outer container 1, two of them lateral walls of spacing paper frame 4 correspond two limiting plates 3 respectively, and two other lateral walls of spacing paper frame 4 correspond two curb plates 22 respectively. The outer side wall of the limiting paper frame 4 close to the limiting plate 3 is abutted to the limiting plate 3, and the outer side wall of the limiting paper frame 4 close to the side plate 22 is abutted to one end, far away from the inner side wall of the carton, of the middle stupefied column 24.
