[0036] Specifically, the working principle of this square tube auxiliary welding fixture is as follows: In use, two square tubes to be welded can be placed inside the first U-shaped plate 132 and the second U-shaped plate 332, respectively. The square tubes are located below the first clamping plate 134 and the second clamping plate 334. The ends of the two square tubes to be welded can then be aligned and fitted together, with the two square tubes in a straight line. Then, the first rotating handwheel 1331 and the first threaded rod 133 can be rotated. The first threaded rod 133 drives the first clamping plate 134 downwards, thereby clamping and fixing the square tubes. Then, the second rotating handwheel 3331 and the second threaded rod 333 can be rotated, causing the second threaded rod 333 to drive the second clamping plate 334 downwards. This allows the second clamping plate 334 to clamp and fix the square tube, so that the welding worker can hold the welding gun to weld the square tube. When it is necessary to clamp the square tube at other welding angles, the rotating plate 320 can be pulled to move it. The rotating plate 320 rotates through the damping shaft 140 and the universal wheel 311, which in turn drives the second clamp 330 and the indicator rod 340 to rotate. The angle of rotation of the second clamp 330 can be known through the indicator rod 340 and the angle scale line 210. Then, the two square tubes can be clamped and fixed by the first clamp 130 and the second clamp 330, so that there is a certain angle between the two square tubes. This allows for the clamping of square tubes that need to be welded at other angles. It has high practicality and a wide range of applications.
