[0035] Specifically, such as Figure 1 As shown, the upper end of the pull rod 3 is rotatably connected to the side of the truck cargo box, and the transport platform 1 is provided with a slide 4. The lower end of the pull rod 3 is slidably connected to the slide 4. When the pull rod 3 rotates, the lower end of the pull rod 3 can move along the guide direction of the slide 4. When the pull rod 3 is driven by an external force to rotate in a direction away from the truck cargo box, the lower end of the pull rod 3 slides in the slide 4 in a direction away from the truck cargo box, and the pull rod 3 applies a pulling force to the transport platform 1, causing the transport platform 1 to rotate parallel to the horizontal direction; when the pull rod 3 is driven by an external force to rotate in a direction close to the truck cargo box, the lower end of the pull rod 3 slides in the slide 4 in a direction close to the truck cargo box, and the pull rod 3 applies a pulling force to the transport platform 1, causing the transport platform 1 to rotate perpendicular to the horizontal direction.

[0036] In this embodiment, the slide 4 is provided on the front side of the transport platform 1 .

[0037] In other optional embodiments, the chute 4 may be provided on the upper end surface or the lower end surface of the transport platform 1 .
