[0026] like Figure 1 and Figure 5As shown, the limiting assembly includes a support box 3 fixedly mounted on the top of the movable frame 9, the internal movable sleeve of the support box 3 is provided with a bidirectional screw 7, the bidirectional screw 7 passes through one side end of the support box 3 and is fixedly connected to a handle 22, the external threaded sleeve of the bidirectional screw 7 is provided with two movable seats 8, the tops of the two movable seats 8 are fixedly mounted with a guard plate 4, and the outside of the guard plate 4 is mounted with multiple protective blocks 5, during the rotation process, the two movable seats 8 outside the bidirectional screw 7 move toward each other along the limiting groove 6, and then drive the guard plate 4 on the top of the movable seat 8 to approach the logistics part during the movement, and then fix the outside of the logistics part through the guard plate 4.
[0027] like Figure 3 and Figure 5 As shown, a limiting groove 6 is opened on the outside of the support box 3, and the movable seat 8 is slidably sleeved in the limiting groove 6. When the bidirectional screw 7 drives the two movable seats 8 on the outside to move toward each other, the two movable seats 8 slide with the limiting groove 6, thereby increasing the stability of the movement of the two movable seats 8.
[0028] like Figure 1 and Figure 2 As shown, a pushing frame 21 is installed on the outside of the bottom box 1, and a reinforcing plate 20 is fixedly installed on the outside of the pushing frame 21. The outside of the pushing frame 21 and the handle 22 are fixedly sleeved with a handle sleeve 19.

[0030] Working principle:
[0031] When in use, the logistics items to be transported are placed on the top of the support box 3, and then the handle 22 is turned clockwise to drive the bidirectional screw 7 to rotate. During the rotation process, the two moving seats 8 outside the bidirectional screw 7 move toward each other along the limit groove 6, and then the guard plate 4 on the top of the moving seat 8 is driven to approach the logistics items during the movement, and then the outside of the logistics items is fixed by the guard plate 4, and then the pushing frame 21 is pushed to make the universal wheel 2 at the bottom of the bottom box 1 drive the bottom box 1 to move. During the movement, when the logistics on the top of the support box 3 vibrates, the support box 3 drives the movable frame 9 at the bottom to move up and down along the outside of the limit rod 16. In this process, the spring 18 outside the limit rod 16 is compressed or stretched, and buffered by the spring 18. When moving, the movable frame 9 drives the wedge block 10 to contact and squeeze the corresponding wedge block 2 14 through the connected fixed rod 15. Under the action of the squeezing force, the spring 2 11 drives the telescopic rod 12 to compress or stretch and further buffered by the spring 2 11, thereby playing a role of buffering and vibration reduction.
