The steel pipe to be welded is passed through the cavity formed by the first arc-shaped clamping plate 4 and the second arc-shaped clamping plate 5 respectively, and the steel pipe is placed between the two wedge-shaped blocks 8. Then, the knob 13 is turned to drive the threaded rod 12 to rotate, thereby driving the wedge-shaped clamping plate 10 to move downward, which can squeeze the surface of the steel pipe to fix the steel pipe. The wedge-shaped block 8 cooperates with the wedge-shaped clamping plate 10 to clamp and fix steel pipes of different diameters.

[0025] In the utility model, both sides of the base 1 are provided with sliding openings 6, and the sliding openings 6 are connected with the sliding grooves 2, and both sides of the inner walls of the sliding openings 6 are provided with multiple card slots 7, and one side of the multiple first sliders 3 is provided with a limiting groove 14, and the limiting groove 14 is slidably connected with a second slider 15, and one side of the second slider 15 passes through the sliding opening 6 and is fixedly connected with a card block 17 by bolts, and the card block 17 is embedded in the card slot 7, and a tension spring 16 is welded on one side of the second slider 15, and the other end of the tension spring 16 is fixed to one side of the inner wall of the limiting groove 14. After the steel pipe is fixed, the card block 17 is pulled to drive the second slider 15 to slide along the limiting groove 14, so that the tension spring 16 can generate tension, and when the card block 17 is separated from the card slot 7, the clamping assembly can be moved, and when one end of the two steel pipes is in contact, the card block 17 is released, and the second slider 15 is driven by the action of the tension spring 16 so that the card block 17 is embedded in the card slot 7 to clamp the clamping assembly.

One end of the sliding rod 11 is welded with a limiting plate. By matching the two sliding rods 11, when the threaded rod 12 is rotated, the sliding rod 11 slides downward with the wedge-shaped clamping plate 10 to guide the wedge-shaped clamping plate 10 to prevent tilting during the movement of the wedge-shaped clamping plate 10 and to avoid loosening of the steel pipe after clamping.

[0026] Working principle: When the steel pipe needs to be clamped, the steel pipe to be welded is passed through the cavity formed by the first arc clamping plate 4 and the second arc clamping plate 5, and the steel pipe is placed between the two wedge blocks 8. Then the knob 13 is turned to drive the threaded rod 12 to rotate, thereby driving the wedge clamping plate 10 to move downward, which can squeeze the surface of the steel pipe to fix the steel pipe. The wedge block 8 and the wedge clamping plate 10 can be used to clamp and fix steel pipes of different diameters. After the steel pipe is fixed, the clamping block 17 is pulled to drive the second slider 15 along the limit groove 14. Sliding can cause the tension spring 16 to generate tension, and when the block 17 is out of the slot 7, the clamping assembly can be moved. When one end of the two steel pipes touches, the block 17 is released, and the second slider 15 is driven by the tension spring 16 so that the block 17 is embedded in the slot 7 to fix the position of the clamping assembly. By matching the two slide bars 11 and rotating the threaded rod 12, the slide bar 11 slides downward with the wedge-shaped clamp 10 to guide the wedge-shaped clamp 10 to prevent the wedge-shaped clamp 10 from tilting during the movement, thereby avoiding loosening of the steel pipe after clamping.
