[0034] like Figures 1 to 6 As shown, preferably, the frame 1 also includes a handle 15; a connecting plate is provided on the first plate body 11, and one end of the handle 15 is connected to the connecting plate of the first plate body 11. Preferably, the handle 15 is hinged to the first plate body 11 to facilitate pulling or pushing the overall bracket 1.

[0035] like Figures 1 to 6 As shown, preferably, the frame 1 also includes a fourth plate body 16; both ends of the fourth plate body 16 are respectively connected to one end of the third plate body 13 away from the first plate body 11, and the orientation of the fourth plate body 16 is consistent with the orientation of the first plate body 11; a lifting ring is provided on the top surface of the fourth plate body 16, and the entire frame 1 is lifted by the lifting ring.

When in use, the height of the L-shaped bracket 22 can be lowered according to the hollow position of the round wooden packaging box, and then the L-shaped bracket 22 is inserted into the hollow part of the round wooden packaging box to increase the height of the L-shaped bracket 22 so that the horizontal end of the L-shaped bracket 22 supports and lifts one end of the round wooden packaging box. This process is adjusted by the hydraulic cylinder 26, and the support frame 27 is lowered or raised by the hydraulic cylinder 26. The rod body 21 and the L-shaped bracket 22 move with the support frame 27 to achieve height adjustment, simplify operation, and facilitate rapid loading and unloading of round wooden packaging boxes and increase transportation speed. In addition, it should be noted that the specific model of the hydraulic cylinder is not an improvement point of this application and will not be elaborated here.
