The sliding block 5 moves the connecting plate 9 backward, and the connecting plate 9 pulls the two sets of connecting rods 10 backward. Both sets of connecting rods 10 move the L-shaped plate 11 and the sliding block 13 inward along the slide groove 12 and the limiting post 22. The two sets of L-shaped plates 11 move the two sets of connecting rods 14, the rotating shaft 19, the connecting plate 21, and the clamping blocks 23 inward. The inward movement of the two sets of clamping blocks 23 clamps the shear nail in the middle, effectively improving the stability of the shear nail welding process and ensuring the shear nail welding clamp... The clamping effect of the holding device is better, which can effectively improve the convenience of operation of the shear nail welding clamping device.
