[0028] In the embodiment of the present utility model, a clamping assembly 5 is arranged on the surface of the threaded rod 3;

[0029] The clamping assembly 5 includes a connecting plate 501 threadedly connected to the threaded rod 3, and sliding grooves are symmetrically provided on both sides of the surface of the connecting plate 501.

[0030] In the embodiment of the present utility model, a balancing assembly 6 is arranged on both sides of the clamping plate 503;

[0032] Working principle: This embodiment provides a fixed support structure for metal structure manufacturing. When in use, first, the telescopic movement of the double-rod hydraulic cylinder 504 drives the two clamping plates 503 to telescope according to the position of the steel beam, so that the clamping plates 503 can be clamped in the grooves on both sides of the steel beam to fix the position of the steel beam. Then, the operation of the motor 404 drives the double-headed worm 403 to rotate, thereby driving the two worm wheels 401 to rotate at the same time. The worm wheel 401 also drives the threaded rod 3 to rotate in the same direction, and enables the clamping assembly 5 to drive the steel beam to move up and down, so that the steel beam to be installed can be moved up and down according to the conditions of different construction sites. The steel beam to be inspected is raised or lowered to different heights, and when clamping steel beams of different lengths, the spring 605 is squeezed to drive the block 606 to disengage from the limiting rack 607, so that the extension rod 602 can move in the cross frame 601 to adapt to steel beams of different lengths. After moving to the appropriate position, the squeezing of the spring 605 is cancelled, so that the spring 605 is reset and drives the block 606 to be clamped in the limiting rack 607, thereby fixing the position of the extension rod 602 and supporting it in the groove of the steel beam through the balance block 608, so that the steel beam can be clamped by the clamping assembly 5 to keep the position of the steel beam in a horizontal balance.
