At this time, the connecting rod 10 can be moved along the guide rod 9, and the connecting rod 10 will drive the clamped sheet metal stamping part to move. When the sheet metal stamping part moves to the appropriate position, the clamping block 16 is released. At this time, the clamping block 16 will be reversed by the force of the torsion spring 15, so that the clamping block 16 is clamped into the clamping slot 17, and the position of the sheet metal stamping part is fixed, so that the position of the sheet metal stamping part can be adjusted, and the sheet metal stamping part can be bent at different positions, which is convenient for bending the sheet metal stamping parts at different positions.

[0025] The bending assembly includes a cylinder 2, which is fixed to the top of the L-shaped plate 4 by bolts.
