10. A construction method for a steel structure processing device according to any one of claims 1 to 9, characterized in that: The specific operations are as follows: When in use, the steel structure is placed on top of the housing (2), and the second electric telescopic rod (301) is started, so that the telescopic end of the second electric telescopic rod (301) drives the first toothed plate (302) to move, and the two first rotating gears (303) are meshed at the front and rear sides of the first toothed plate (302) and rotate along with the movement of the first toothed plate (302). Subsequently, the first rotating gears (303) drive the fixing frame (306) to move through the connecting rod (305) while rotating, and the connecting plate (307) follows The fixing plate (308) moves along with the movement of the fixing frame (306), and the fixing plate (308) moves along with the movement of the connecting plate (307), and the two fixing plates (308) are brought close to each other, so that the front and rear sides of the steel structure are clamped and fixed; the rotating disk (311) is rotated, and when the rotating disk (311) rotates, the threaded rod (310) is driven to rotate and move toward the bottom, and the clamping plate (312) moves along with the movement of the threaded rod (310), and the top of the steel structure is fixed by the clamping plate (312); When the welding head (11) is installed or removed, the two limit plates (12) at the top of the welding head (11) are clamped to the two sides of the protective shell (9), and the fixed plate (1002) is rotated to drive the rotating rod (1001) to rotate. The rotating rod (1001) rotates to drive the first bevel gear (1003) to rotate. When the first bevel gear (1003) rotates, it drives the second bevel gear (1004) to rotate. When the second bevel gear (1004) rotates, it drives the transmission rod (1005) to rotate. When the transmission rod (1005) rotates, it drives the second rotating gear (1006) to rotate. The second rotating gear (1006) rotates. When the second tooth plates (1007) are moved, the two second tooth plates (1007) are driven to move in opposite directions. When the second tooth plates (1007) move, the baffle plate (1008) is driven to move. When the baffle plate (1008) moves, the clamping block (1009) is driven to move, and the clamping block (1009) is moved into the fixed groove on the limit plate (12), thereby completing the rapid installation of the limit plate (12); when it is necessary to disassemble the limit plate (12), the fixed disk (1002) is rotated in the opposite direction to separate the clamping block (1009) from the fixed groove inside the limit plate (12), thereby disassembling the limit plate (12), and thus completing the disassembly of the welding head (11).
