The left fixing plate 8 is folded to form an interlocking gap with the left side of the carton, and the inner lining plate is fixed by interlocking with this gap, thus forming a reinforcing lining structure on the inner side of the carton by fitting it against the left connecting plate 3. Similarly, the right fixing plate 9 is folded to form an interlocking gap with the right side of the carton, and the inner lining plate is fixed by interlocking with this gap, thus forming a reinforcing lining structure on the inner side of the carton by fitting it against the right connecting plate 5. The interlocking gaps between the inner lining plate and the left and right fixing plates 8 and 9 enable rapid assembly, and the structure that fits against the inner side of the carton strengthens the carton. Furthermore, the left fixing plate 8 is provided with a first crease 10, a second crease 11, a third crease 12, and a fourth crease 13 spaced apart along the direction away from the base plate 1. The middle part of the left fixing plate 8 is folded along the aforementioned creases to form a structure protruding from the left fixing plate 8. This structure forms an insertion gap with the left connecting plate 3. As can be seen from the above description, by setting the first crease 10, the second crease 11, the third crease 12, and the fourth crease 13 on the left fixing plate 8, the folded left fixing plate 8 can form a "door"-shaped structure with a protruding center. This structure forms an insertion gap with the left connecting plate 3, which can be used for inserting the inner lining plate. Furthermore, the right fixing plate 9 is provided with a fifth crease 14, a sixth crease 15, a seventh crease 16, and an eighth crease 17 spaced apart along the direction away from the base plate 1. The middle part of the right fixing plate 9 is folded along the aforementioned creases to form a structure protruding from the right fixing plate 9. This structure forms an insertion gap with the right connecting plate 5. As described above, by setting the fifth fold 14, the sixth fold 15, the seventh fold 16 and the eighth fold 17 on the right fixing plate 9, the folded right fixing plate 9 can form a "door" shaped structure with a protrusion in the middle, and this structure forms an insertion interval with the right connecting plate 5 that can be used for inserting the inner lining plate.Furthermore, the left fixing plate 8 has a first insert 18 at its end away from the left connecting plate 3, and the left connecting plate 3 has a first socket 19 corresponding to the first insert 18, which is then inserted and fixedly connected to the first socket 19.

The inner lining plate includes a first inner lining plate 6, the middle of which is fitted with the front connecting plate 23, and its two ends are folded and inserted into the insertion gaps on both sides of the bottom plate 1. As can be seen from the above description, the front side plate 22 and the front connecting plate 23 are folded to form the front structure of the carton. Through the abutting arrangement of the first inner lining plate 6 and the front connecting plate 23, the front structure of the carton can be strengthened. At the same time, the cooperation of its two ends with the insertion gaps on both sides of the bottom plate 1 can also abut against the left and right structures of the carton and improve its strength. Furthermore, it also includes a rear side plate 24. The rear side plate 24 is connected to the rear side of the bottom plate 1. The inner lining plate also includes a second inner lining plate 7, the middle of which is fitted with the rear side plate 24, and its two ends are folded and inserted into the insertion gaps on both sides of the bottom plate 1. As described above, the rear side panel 24 is folded to form the rear structure of the carton. The second inner liner 7, by abutting against the rear side panel 24, strengthens the rear structure of the carton. Simultaneously, the interlocking intervals at both ends of the second inner liner 7 with the sides of the bottom plate 1 also abut against the left and right sides of the carton, enhancing its strength. Furthermore, the ends of the first inner liner 6 and the second inner liner 7 are detachably connected within the corresponding interlocking intervals. As described above, the detachable connection design of the first inner liner 6 and the second inner liner 7 allows for convenient installation; they can be replaced when necessary, using other materials to improve the carton's strength. Furthermore, the end of the first inner liner 6 has a first slot 25, and the end of the second inner liner 7 has a second slot 26; the first slot 25 and the second slot 26 interlock. As described above, the detachable connection between the two is achieved through the interlocking of the first slot 25 at the end of the first inner liner 6 and the second slot 26 at the end of the second inner liner 7.
