[0041] The working principle and use process of the present invention are as follows: when the box clamping device which is convenient for angle adjustment is used, the first motor 3 is installed on the mounting plate 1. When the angle adjustment is required, the first motor 3 is started to drive the rotating rod 4 to rotate, so that the adjusting block 6 moves left and right in the adjusting groove 2 with the help of the thread 5 and the rotating rod 4, thereby driving the adjusting rod 7 to pull the adjusting disk 9 fixed on the supporting rod 8 to rotate, so that the clamping assembly on the cross plate 10 can follow the angle rotation adjustment, so that the clamping angle is aligned with the angle of the box, increasing the contact area between the clamping assembly and the box, avoiding the problem of personal or financial damage caused by the box falling due to unstable angle clamping, making the clamping more stable and firm, improving the flexibility and safety of the device, and installing the groove 11 is convenient for fixing the stable gear 13 through the connecting rod 12, which facilitates the better rotation of the gear 13 on the connecting rod 12, so as to achieve better left and right movement of the moving block 15 through the rack plate 14, and force the synchronous movement of the moving block 15 connected to the rack plate 14, and the auxiliary adjustment is more stable.
