After the two poles are connected, the fixing screw 2 is rotated to fix the position of the pole.

[0035] In this way, by fixing the fixing screws 2 and the C-shaped rail 1, the two rack rods are restricted at a fixed angle by the fixing parts 4 and the arc ruler 3, thereby reducing movement and dislocation during welding and facilitating welding.

When the C-rail 1 is rotated, the arc ruler 3 slides, and the opening and closing angle of the C-rail 1 is determined by the angle scale. The fixing member 4 can be selected as a rectangular block fixedly connected to the C-rail 1, and the arc ruler 3 can slide through the rectangular block, and the rectangular block is threaded with a screw, and the screw is pressed against the arc ruler 3 to fix the position.
