The fork 12 is fixed to the bottom of the forklift body on the side close to the glass 3, and the bracket 13 is fixed to the top of the forklift body on the side close to the glass 3. The anti-overturning mechanism 2 is fixed on the bracket 13; multiple glasses 3 are stacked on a glass rack 4, and the glass rack 4 is L-shaped. The vertical plate of the glass rack 4 is set away from the AGV forklift 1, and there is a gap between the bottom of the glass rack 4 and the ground, which is convenient for the fork 12 to be inserted into and lift the glass rack 4.

In this embodiment, the universal pressure block 26 is made of sponge or rubber, and the universal pressure block 26 is spherical; when the universal pressure block 26 presses against the glass 3 and reaches a specified pressure (excessive pressure will cause the glass to break), the thrust sensor sends a signal to the control mechanism, and the control mechanism controls the servo motor 21 to cut off the power, and controls the first brake to hold the servo motor 21, and the second brake to hold the electric cylinder 22, to prevent the servo motor 21 and the electric cylinder 22 from continuing to operate.
