It supports single-person operation, improves work efficiency, and is convenient and quick to adjust the position to ensure welding accuracy and flatness.

[0043] As an optional embodiment of the utility model, the clamping mechanism includes

[0044] A plurality of clamping posts 8, wherein the plurality of clamping posts 8 are respectively fixedly connected to the fixing seat 6 and the clamping hoop 18 at the top of the fixing seat 6;

[0045] A plurality of telescopic columns 9, wherein the plurality of telescopic columns 9 are respectively fixedly connected to the positioning seat 10 and the clamp 18 at the top of the positioning seat 10;

[0046] It also includes a clamping block 11 elastically connected to the clamping column 8 and a limiting block 12 fixedly connected to the telescopic end of the telescopic column 9. A cavity is opened inside the limiting block 12, and the clamping block 11 is squeezed and fitted inside the cavity when in use.

[0047] In this embodiment, the clamping block 11 and the limiting block 12 are wedge-shaped. Through the cooperation of the clamping column 8 and the telescopic column 9, the steel pipe is accurately positioned to improve the welding accuracy and flatness; the telescopic column 9 provides flexible adjustment to adapt to steel pipes of different lengths; the extrusion fit design of the clamping block 11 and the limiting block 12 ensures stable fixation to prevent the steel pipe from being displaced or deflected during welding; at the same time, the elastic connection and cavity design allow the clamping mechanism to be quickly installed and disassembled, thereby improving the convenience and efficiency of operation.

[0054] When the utility model is used, the steel pipes are first slidably connected and then connected by a clamping mechanism. Specifically, the first steel pipe 16 is first placed on the first sliding seat 3 and the fixed seat 6, and then the second steel pipe 17 is placed on the second sliding seat 14 and the positioning seat 10. The design of the ball 5 ensures the precise guidance and smooth movement of the first steel pipe 16 and the second steel pipe 17 during the sliding process. When the first steel pipe 16 and the second steel pipe 17 are adjusted to the appropriate position, the clamping block 11 and the limit block 12 are squeezed to achieve stable fixation of the steel pipe, effectively preventing the displacement or deflection of the steel pipe during welding. In addition, a plurality of springs 13 are arranged between the clamping column 8 and the clamping block 11, which are evenly spaced and distributed in the circumferential direction along the axis. These springs provide uniform elastic force, which enhances the buffering performance and stability of the clamping mechanism. The entire structural design ensures that the first steel pipe 16 and the second steel pipe 17 can be kept on the same axis during welding, thereby improving welding accuracy and flatness. After welding is completed, the clamping mechanism can be quickly disassembled by separating the clamping block 11 and the limiting block 12.
