[0033] The distance between the two groups of clamping mechanisms 12 is adjusted according to the width of the aluminum alloy plate that needs to be bent. The control panel 2 controls the first motor 7 to start. The first motor 7 drives the screw rod 6 to rotate and drives the slider 8 to move. The slider 8 drives the fixed plate 9 to move and drives the clamping mechanism 12 to move. The distance between the two groups of clamping mechanisms 12 is adjusted. During bending, only the aluminum alloy plate between the two groups of clamping mechanisms 12 is bent, which has a limiting effect and improves the bending accuracy and practicability.

[0034] The second motor 124 is started by controlling the control panel 2. The second motor 124 drives the threaded rod 123 to rotate and drives the sliding block 125 to move.
