The first reinforcement block 8 can reinforce the servo motor 42 through the connection between itself and the placement rack 31, so that the servo motor 42 can be sufficiently stable and not prone to shaking when in use.

[0032] Working principle: When the utility model is used, the staff can place the material to be moved on the upper side of the placement rack 31 through a crane or other device, and then connect the connecting hook 25 with the fixed hook 33. Then the staff can start the servo motor 42 and the cylinder 46. The servo motor 42 will drive the bidirectional screw rod 41 to rotate through operation, and when the bidirectional screw rod 41 rotates, it can smoothly drive the two limit plates 44 to move in opposite directions. After the limit plates 44 move to a certain distance, they can move to the outside of the material, thereby clamping and limiting the material. At the same time, the cylinder 46 can push the clamping plate 47 to clamp the clamping plate 47 to the outside of the material, thereby further improving the stability of the material when being moved. After that, the staff only needs to lift and move the material through the crane 21, and move the material through the moving wheel 22.
