[0002] Welding is an important material processing technology with a wide range of critical functions. Welding uses heating or pressurizing to achieve atomic bonding between two or more materials, thereby achieving a tight connection. This connection method is not only strong and reliable, but also can form a continuous structure to meet various engineering needs. The welding of large steel materials is usually carried out using large welding equipment, while small welding processes such as steel bar construction are usually manual welding by workers. When performing welding processes, workers usually use welding pliers to clamp the steel bars for auxiliary welding work. However, the use of welding pliers is usually not precise and it is easy to weld crookedly. Therefore, a small clamping device for welding is needed.

[0026] It should be noted that the first curved plate 12 and the second curved plate 13 are installed in a staggered manner and form a latch structure with the first slot 121 and the second slot 131 respectively. The first curved plate 12 and the second curved plate 13 are centered on the central axis of the hinge shaft 101, so that when the first mounting plate 10 and the second mounting plate 11 rotate, the side surfaces of the first curved plate 12 and the second curved plate 13 are flush with each other. The middle portion of the first bolt 134 passes through the interior of the arc groove 122. By tightening the first bolt 134, the tightness between the first curved plate 12 and the second curved plate 13 can be adjusted, thereby achieving the purpose of adjusting the angle;

[0027] Furthermore, the first handle 135 is twisted to extend the first bolt 134 and no longer press against the top of the arc-shaped slot 122;

[0028] Furthermore, according to the required welding angle, the first mounting plate 10 and the second mounting plate 11 are rotated so as to be offset at an angle under the connection of the hinge shaft 101, so that the first curved plate 12 and the second curved plate 13 are close to each other.

The function of the rubber pad 164 is to prevent the bottom of the second bolt 162 from leaving marks on the surface of the steel.

[0033] Furthermore, a steel bar is passed through the first annular plate 14 and the second annular plate 15 above the first mounting plate 10;

[0034] Furthermore, the second screw handle 163 on the first annular plate 14 is screwed, and each second bolt 162 is passed through each second nut 161 and screwed inwards until each rubber pad 164 is tightly pressed against the surface of the front steel member.

[0035] Furthermore, another steel bar is passed through the first annular plate 14 and the second annular plate 15 above the second mounting plate 11;

[0036] Furthermore, the second handle 163 on the first annular plate 14 is screwed, and each second bolt 162 is passed through each second nut 161 and screwed inwards until each rubber pad 164 is pressed tightly against the surface of the front end of the other steel member.

[0037] Furthermore, after the distance between the two second annular plates 15 is adjusted, the second handle 163 on the second annular plate 15 is screwed, and each second bolt 162 is passed through each second nut 161 and screwed inward until each rubber pad 164 is tightly pressed against the surface of the rear end of the two steel bars.

The first mounting plate 10 and the second mounting plate 11 can no longer rotate under the limit of the first arc plate 12 and the second arc plate 13. A piece of steel is passed through the first annular plate 14 and the second annular plate 15 above the first mounting plate 10, and the first annular plate 13 is screwed. 4, screw each second bolt 162 through each second nut 161 inwards until each rubber pad 164 is pressed tightly against the surface of the front end steel, pass another steel through the first annular plate 14 and the second annular plate 15 above the second mounting plate 11, screw the second screw handle 163 on the first annular plate 14, screw each second bolt 162 through each second nut 161 inwards until each rubber pad 164 is pressed tightly against the surface of the front end of the other steel, shake the crank 175, rotate the threaded rod 174, and connect it through the nut. The threaded tube 152 drives the second annular plate 15 to move. Under the common limitation of the sliding tube 151 and the sliding rod 173 as well as the sliding groove 153 and the sliding bar 154, the second annular plate 15 moves smoothly on the first mounting plate 10 and the second mounting plate 11 until it is adjusted to a suitable position. When the distance between the two second annular plates 15 is adjusted, the second tightening handle 163 on the second annular plate 15 is screwed, and each second bolt 162 is passed through each second nut 161 and screwed inward respectively until each rubber pad 164 is pressed tightly against the surface of the rear end of the two steel materials.
