The two ends of the adjusting steel cable 303 are fixedly connected to the connecting roller 203 and the tensioning ring 302 respectively. The telescopic rod 204 pushes the fixed frame plate 305 while pulling the adjusting steel cable 303. The adjusting steel cable 303 retracts the upper and lower layers of the movable clamps 3, so that the upper and lower ends of the workpiece are tightened, and multiple fixed clamping operations are performed through the same driving structure to improve the working effect.

[0023] The upper and lower ends of the movable clamp 3 are both equipped with positioning claws 301, the positioning claws 301 are welded to the movable clamp 3, and the upper and lower ends of the movable clamp 3 are both slidably connected to the fixed frame plate 305, and a spring rod 304 is installed in the middle of the movable clamp 3, and the spring rod 304 is used for buffering and rebounding, so that the position of the clamp structure is more stable to improve the working effect.

[0024] Specifically, during use, the workpiece in the middle of the movable clamp 3 is clamped, and the telescopic rod 204 pushes the fixed frame plate 305 while pulling the adjusting cable 303. The adjusting cable 303 retracts the upper and lower layers of the movable clamps 3, thereby tightening the upper and lower ends of the workpiece.

The punching and shearing machine bracket 1 is fixed to the punching and shearing machine. After the fixing is completed, the clamping work is performed. During use, the hydraulic cylinder 201 is driven to extend, and the hydraulic cylinder 201 drives the telescopic rod 204 to extend, so that the positions of the two fixed frame plates 305 are translated and approached, and the workpiece in the middle of the movable clamp 3 is clamped. While the telescopic rod 204 pushes the fixed frame plate 305, it pulls the adjusting steel cable 303.
