[0072] Specifically, the operator controls the second motor 17 to work. The work of the second motor 17 can drive the connecting rod and the second bevel gear 16 to rotate. At the same time, through the meshing of the second bevel gear 16 and the first bevel gear 15, the first bevel gears 15 and the first threaded rods 14 on both sides of the first cavity are driven to rotate in opposite directions, so that the moving blocks 13 and the electric grippers 7 on both sides of the first cavity move relatively, so that the electric gripper 7 can clamp and fix the anti-seismic support plates of different specifications.

[0073] Refer to Figure 4 , the lifting mechanism includes a threaded hole, a second threaded rod 18, and a synchronous rotation mechanism.

[0074] Specifically, the operator controls the third motor 21 to work. The operation of the third motor 21 can control the rotation of one of the second threaded rods 18 and the second gear 19. At the same time, through the meshing of the second gear 19 and the second toothed ring 20, multiple second threaded rods 18 and second gears 19 can be driven to rotate synchronously. Furthermore, through the threaded fit between the second threaded rod 18 and the threaded hole, the support ring 8 and the support column 5 are driven to adjust their heights, so that the height of the seismic support plate can be adjusted, and the seismic support plate can be placed on the lower module for bending.

[0075] In this embodiment, during use, the operator places the seismic support plate between the two electric grippers 7. Then, the operator controls the second motor 17 to work.

At the same time, through the meshing of the second bevel gear 16 and the first bevel gear 15, the first bevel gears 15 and the first threaded rods 14 on both sides of the first cavity are driven to rotate in opposite directions. Furthermore, the moving blocks 13 and the electric grippers 7 located on both sides of the first cavity move relatively, so that the electric grippers 7 can clamp and fix seismic support plates of different specifications. Then, the operator controls the third motor 21 to work. The operation of the third motor 21 can control the rotation of one of the second threaded rods 18 and the second gear 19. At the same time, through the meshing of the second gear 19 and the second toothed ring 20, multiple second threaded rods 18 and second gears 19 can be driven to rotate synchronously. Furthermore, through the threaded fit between the second threaded rod 18 and the threaded hole, the support ring 8 and the support column 5 are driven to adjust their heights, so that the height of the seismic support plate can be adjusted. Thus, the seismic support can be controlled by the electric slide table 4 to move, and together with the operation of the bending machine body 1, the seismic support plate is placed on the lower module for bending. After one side wall of the seismic support plate is bent, the operator can, through the operation of the electric slide table 4, move the bent seismic support out from between the upper module and the lower module. Then, the operator controls the first motor 12 to work. The operation of the first motor 12 can control the driving rod 11 to rotate. At the same time, through the cooperation of the chute and the slider, the first gear 10 is driven to rotate. At the same time, through the meshing of the first gear 10 and the first annular rack, the support column 5 and the support block 6 are driven to rotate, so that the angle of the seismic support clamped on the support block 6 can be adjusted, so that the other side wall of the seismic support is aligned with the bending machine body 1. Thus, through the operation of the electric slide table 4, the seismic support extends into the bending machine body 1, which is convenient for bending the opposite side walls of the seismic support, thereby improving the bending efficiency.
