Then, by rotating the first adjusting sleeve 54, the first adjusting sleeve 54 drives the first connecting rod 55 to move vertically downward, and the first connecting rod 55 drives the first fixing block 56 to move vertically downward, and the first fixing block 56 drives the first guide rod 57 to move vertically downward in the first guide groove 52. Subsequently, the limit block 11 is pulled according to the width of the steel structure component, and the limit block 11 drives the slider 9 on the sleeved outer rod 10 to slide in the slide groove 8, so that the limit block 11 moves horizontally, and at the same time, the adjustment component is pulled to rotate on the second fixed block 66, so that it is close to the bottom surface of the steel structure component, and the limit block 11 is clamped on the first fixed block 56, and then the limit bolt 12 is manually rotated, and one end of the limit bolt 12 is rotated and inserted into the threaded slot 58, so as to position the adjustment component, stably clamp the four sides of the steel structure component, and improve the clamping stability.

[0039] Furthermore, the sleeve block 14 is pulled to move horizontally on the reinforcing rod 13, and then the threaded rod 16 is manually rotated and adjusted, and the threaded rod 16 drives the clamping plate 17 to move horizontally, so that the clamping plates 17 on the first limit assembly 5 and the second limit assembly 6 move relatively horizontally, thereby further clamping the steel structure component to make it more stable. Then, the welding seam of the steel structure welding connection is welded by electric welding equipment. The installation is flexible, and the distance can be adjusted arbitrarily according to the steel structure welding, and the steel structure weldment can be stably clamped and limited.
