[0019] Detailed Implementation: First, place the workbench 1 in a suitable position. Then, place the two steel structures to be connected into the two central through holes respectively. At this time, start the drive motor 412 as needed. The drive motor 412 drives the rotating shaft 411 and gear 410 to rotate.

A sliding hole is opened on one side of the inside of the connecting box 503, and the sliding hole is connected to the rectangular through hole. Multiple sets of rectangular frames 504 are arranged in a circular array on one side of the annular plate 502, and each set of rectangular frames 504 is composed of multiple rectangular frames 504. One side of the rectangular frame 504 is fixedly connected to one side of the annular plate 502. Multiple sets of rectangular sliders 505 are arranged in a circular array on one side of the annular plate 502, and each set of rectangular sliders 505 is composed of multiple rectangular sliders 505.

[0021] Detailed implementation: While the fixed frame 405 moves, it drives the rectangular slider 505 to slide inside the rectangular frame 504 and the adjusting seat 3 through the connecting box 503 and the connecting plate 506. After completing the initial limiting and fixing of the steel structure, the electric push rod 501 drives multiple sets of rectangular frames 504 to move. During the movement of the rectangular frame 504, it drives the connecting plate 506 and the limiting block 507 to move synchronously through the rectangular slider 505. This allows the limiting block 507 to quickly and synchronously limit and fix the arc-shaped fixing block 408, helping to convert the flexible fixing of the arc-shaped fixing block 408 into a rigid fixing. This effectively ensures the applicability and portability of the device during use. During use, the interiors of the fixed frame 405, the arc-shaped fixing block 408, the rectangular slider 505, the connecting plate 506, and the limiting block 507 can be cleaned periodically by an external air gun head.

[0022] Working Principle: In use, first place the workbench 1 in a suitable position, then place the two steel structures to be connected into the two central through holes respectively. At this point, start the drive motor 412 as needed. The drive motor 412 drives the rotating shaft 411 and gear 410 to rotate. Utilizing the linkage effect between gear 410 and ring gear 409, power is transmitted to ring gear 409, causing ring gear 409 to drive the rotating ring 401 and multiple arc-shaped protrusions 402 to rotate, pressing against roller 403 and the first spring 406. This causes roller 403 to move connecting block 404, fixing frame 405, second spring 407, and arc-shaped fixing block 408 towards the steel structure, fixing steel structures of different sizes. The outer surface of the steel structure is pressed against the second spring 407 by the arc-shaped fixing block 408. The flexible second spring 407 and arc-shaped fixing block 408 ensure that the steel structure is properly aligned with the surrounding structure. To meet the fixing requirements of steel structures of different shapes, during this process, the fixing frame 405 will drive the rectangular slider 505 to slide inside the rectangular frame 504 and the adjusting seat 3 through the connecting box 503 and the connecting plate 506. After completing the initial limiting and fixing of the steel structure, the electric push rod 501 will drive multiple sets of rectangular frames 504 to move. During the movement, the rectangular frame 504 will drive the connecting plate 506 and the limiting block 507 to move synchronously through the rectangular slider 505, so that the limiting block 507 can quickly and synchronously limit and fix the arc-shaped fixing block 408, and help to convert the flexible fixing of the arc-shaped fixing block 408 into rigid fixing. After the fixing of the steel structure is completed, the rotation drive unit can drive the adjusting seat 3 to rotate according to actual needs to adjust the welding angle between the two steel structures. Then, the sliding seat 2 and the adjusting seat 3 are moved through the two linear modules to ensure the welding distance between the two steel structures.
