Then, after the first welding plate 5 is placed under the L-shaped plate 21, the screw 23 is rotated, and then the screw 23 drives the first anti-skid pad 22 to move downward, and then the first welding plate 5 can be pressed, ensuring that the position of the first welding plate 5 will not move, and at the same time, the first anti-skid pad 22 can protect the first welding plate 5, ensuring that the first welding plate 5 will not be scratched. A hand wheel 24 is fixedly connected to the end of the screw 23. Thus, it is convenient to twist the screw 23, which is convenient for the work and improves efficiency.
