The four protective members 31 are bonded to the four corners of the carton body 1. The protective members 31 are arranged at a right angle. The four protective members 31 are fixedly connected to one side corresponding to each other with a connecting rod 32. There are multiple connecting rods 32. The lower end of the protective member 31 extends significantly outward and exceeds the lower surface of the carton body 1. A buffer assembly 33 is arranged at the lower end of the protective member 31, and an auxiliary mechanism 35 is arranged on the surface of the connecting rod 32.

[0027] In this embodiment: four right-angled protective members 31 cooperate with a plurality of connecting rods 32 to reinforce the entire carton body 1, reduce the damage to fruits and vegetables caused by the deformation of the carton body 1 due to lateral and longitudinal pressure, and at the same time, the lower end of the protective member 31 extends outward, beyond the lower surface of the carton body 1, so that the carton body 1 can be suspended in the air to reduce the phenomenon of moisture on the bottom.

[0028] Specifically, a support member 36 is fixedly connected to the surface of the protective member 31, and the support member 36 is located below the carton body 1. The protective member 31 cooperates with the support member 36 to lift the bottom of the carton body 1 and improve the overall protection.

[0029] Specifically, the buffer assembly 33 includes a support rod 331, a slide groove is formed on the lower surface of the protective member 31, the support rod 331 is slidably connected to the inner wall of the slide groove, and a spring 332 is fixedly connected to the side of the support rod 331 corresponding to the inner wall of the slide groove of the protective member 31.

[0030] In this embodiment, the spring 332 cooperates with the support rod 331 to play a certain buffering role, thereby providing shock absorption and buffering during transportation.

[0031] Specifically, a guide column 333 is fixedly connected to the surface of the support rod 331, a positioning hole is opened on the surface of the protective member 31, the positioning hole is connected to the slide groove on the surface of the protective member 31, the guide column 333 is slidably connected to the inner wall of the positioning hole on the surface of the protective member 31, and the guide column 333 cooperates with the positioning hole on the surface of the protective member 31 to play a guiding role, and at the same time can limit the movement range of the support rod 331.

[0032] Specifically, the surfaces of the four support rods 331 are fixedly connected with the bottom plate 34 , and the bottom plate 34 can increase the contact area.

[0033] In this embodiment: the support rods 331 cooperate with the bottom plate 34 to facilitate stacking of the carton bodies 1 and improve stability.

[0034] Specifically, the auxiliary mechanism 35 includes a fixing rod 352. Two grooves are respectively provided on the surfaces of the connecting rods 32 on both sides of the carton body 1. There are multiple fixing rods 352. The multiple fixing rods 352 are respectively fixedly connected to the inner walls of the four grooves.
