It should be noted that, in this process, the left support member 13, the right support member 14, the front support member 15 and the rear support member 16 are formed at the same time. Preferably, as shown in fig. 7, the right sidewall 112 is provided with a first inserting buckle 37, and when the right sidewall 112 abuts against the fifth portion 35, the first inserting buckle 37 is sequentially inserted into the fifth inserting groove 36 on the fifth portion 35 and the fifth inserting groove 36 on the first portion 31, so that the structure of the inner box body 11 is more stable.

Step three: the part of the fifth part 35 for forming the right limiting boss 12 is folded along the folding line in sequence towards the direction close to the right side wall 112, and is folded by 90 degrees each time, and finally the structural schematic diagram of the forming state of the right limiting boss of the buffer box shown in fig. 10 is formed. Preferably, as shown in fig. 8, the limiting boss 12 is provided with a second inserting buckle 38, and when the limiting boss 12 is molded, the second inserting buckle 38 is sequentially inserted into the fifth slot 36 on the fifth portion 35 and the fifth slot 36 on the first portion 31, so that the structure of the limiting boss 12 is more stable.

Step four: the part of the fifth portion 35 for forming the receiving protrusion 121 is folded along the folding line in sequence toward the direction close to the left sidewall 111, and each time the fifth portion is folded by 90 °, the top plate 1211 of the receiving protrusion 121 is inserted into the fourth slot 1112 on the left sidewall 111 and extends out from the outer side of the left sidewall 111, so as to form the structural diagram of the state that the top plate of the receiving protrusion is inserted into the fourth slot as shown in fig. 11, at this time, the accessory 200 can be placed inside the receiving protrusion 121. Finally, the supporting plate 1212 is folded down along the folding line and abuts on the upper surface of the fifth portion 35, and the schematic structural view of the formed state of the buffer box as shown in fig. 12 is finally formed.
