By setting the maximum diameter of the connecting plate 11 to be smaller than the maximum diameter of the inner cavity of the slide groove 17, it is avoided that the connecting plate 11 moves too long when the device performs reciprocating motion, causing the structure to jam.

[0027] Reference Figure 1 、 Figure 4 and Figure 5 As shown, in this embodiment: an L-shaped plate 20 is fixedly connected to one side of the second support frame 3, and the interior of the L-shaped plate 20 is slidably connected to a limiting rod 21. A plurality of limiting grooves 22 are provided on one side of the extension rod 19. The interior of the limiting groove 22 is slidably connected to the surface of the limiting rod 21. By pulling the limiting rod 21, the interior of the limiting groove 22 is disengaged to release the fixation of the extension rod 19. At this time, it is convenient for the user to adjust the height of the extension rod 19 and complete the fixation after adjustment, thereby adapting to vehicles and loading platforms of different heights.

When the limit rod 21 is pulled and the limit rod 21 needs to be restored to its original position, the limit rod 21 is released, so that the second spring 24 pushes the limit ring 23 due to the recovery of elastic force. At this time, the limit ring 23 will drive the limit rod 21 to insert into the inside of the limit groove 22, thereby resetting the limit rod 21, making it convenient for the operator to reuse it.

[0029] Reference Figure 1 、 Figure 4 and Figure 5As shown, in the present embodiment: the inside of the L-shaped plate 20 is rotatably connected with a rotating rod 25, one end of the rotating rod 25 away from the L-shaped plate 20 is fixedly connected with a limiting block 26, when the limiting rod 21 is away from the inside of the limiting groove 22, rotate the rotating rod 25, drive the limiting block 26 to block in front of the limiting ring 23, then loosen the limiting rod 21, so that the second spring 24 drives the limiting ring 23 to contact with the limiting block 26, at this time the limiting block 26 will limit the limiting ring 23, then when the limiting rod 21 needs to be inserted into the inside of the limiting groove 22, rotate the rotating rod 25, so that the limiting block 26 no longer blocks the limiting ring 23, then the second spring 24 will drive the limiting rod 21 to insert into the inside of the limiting groove 22.

[0030] Working principle: The user places the logistics box on the conveyor belt 4, starts the drive motor 6 to drive the first rotating shaft 5 to make the conveyor belt 4 transport, and at the same time drives the second rotating shaft 7 to rotate, and then the turntable 9 drives the first connecting rod 10 to rotate.

The maximum diameter of the connecting plate 11 is set to be smaller than the maximum diameter of the inner cavity of the slide groove 17 to avoid the connecting plate 11 moving too long when the device is doing reciprocating motion, which causes the structure to jam. By pulling the limit rod 21 to drive it out of the limit groove 22, the extension rod 19 is released. At this time, it is convenient for the user to adjust the height of the extension rod 19 and complete the adjusted fixation to adapt to vehicles and loading platforms of different heights. When the limit rod 21 is pulled and the limit rod 21 needs to be restored to its original position, the limit rod 21 is released, so that the second spring 24 pushes the limit ring 23 due to the recovery of the elastic force. At this time, the limit ring 23 will drive the limit rod 2 1 is inserted into the limiting groove 22, which plays the role of resetting the limiting rod 21, making it convenient for the operator to reuse it. When the limiting rod 21 is away from the limiting groove 22, the rotating rod 25 is rotated to drive the limiting block 26 to block the front of the limiting ring 23, and then the limiting rod 21 is released, so that the second spring 24 drives the limiting ring 23 to contact the limiting block 26. At this time, the limiting block 26 will limit the limiting ring 23. When the limiting rod 21 needs to be inserted into the limiting groove 22, the rotating rod 25 is rotated so that the limiting block 26 no longer blocks the limiting ring 23, and then the second spring 24 will drive the limiting rod 21 to insert into the limiting groove 22.
