[0028] Working principle:

[0029] When in use, the box body 1 is fixed to the ground as a foundation, the sheet metal is placed horizontally on the cutting table 2, and the surface of the sheet metal to be bent is close to the top of the bending knife 37.

[0030] When the sheet metal is fixed, the hydraulic rod 441 is retracted, so that the retracted hydraulic rod 441 drives the protruding block 448, so that the protruding block 448 moves toward the base 440, and the movement of the protruding block 448 drives the clamping block 443 to move, so that the clamping block 443 moves toward the base 440, and the movement of the clamping block 443 drives the slider 446 to slide, so that the slider 446 slides along the slide rail 445.
