[0028] Working principle: When the utility model is in use, the steel structure to be welded can be horizontally placed between two U-shaped plates 18. By rotating the first knob 21, the rotation of the first knob 21 drives the rotation of the first threaded rod 19, and drives the circular plate 20 to move downward, so as to clamp and fix the steel structure. When it is necessary to clamp a steel structure with a smaller size, rotate the second knob 15 to drive the rotation of the second threaded rod 14. The rotation of the second threaded rod 14 drives the relative movement of the two cylinders 13. The relative movement of the two cylinders 13 can drive the relative sliding of the two square-hole round tubes 4 through the two swing rods 9, so as to drive the relative movement of the two moving plates 3, and further clamp and fix the steel structure with a smaller size. On the contrary, it can clamp and fix the steel structure with a larger size, improving the clamping stability and practicability of the clamping device. When it is necessary to adjust the angle of the steel structure, the servo motor 8 can be started by an external power supply. The operation of the servo motor 8 drives the rotation of the right-side rotating shaft 6. The rotation of the rotating shaft 6 drives the rotation of the rotating square rod 5. The rotation of the rotating square rod 5 drives the rotation of the two square-hole round tubes 4, so as to drive the rotation of the moving plate 3, and thus adjust the welding position of the steel structure. In addition, the L-shaped rod 27 can be pulled out of the inner cavity of the cross-shaped hole 26. Then, by rotating the rocker 24, the turntable 23 can be driven to rotate, and the U-shaped plate 18 can be driven to rotate through the rotating rod 22, so as to turn the two U-shaped plates 18 by ninety degrees to vertically clamp and fix the n-shaped or m-shaped steel structure. And by rotating the third knob 36, the third threaded rod 34 can be driven to rotate. The rotation of the third threaded rod 34 drives the lifting of the second threaded sleeve 33, and drives the lifting of the lifting ring 31 through the sliding of the connecting plate 32 on the vertical rod 37. By adjusting the height of one side of the U-shaped plate 18, the Z-shaped steel structure can be clamped and fixed, further improving the practicability of the clamping device.
