Activating the first electric push rod 6 pushes the pressure mechanism downward through the fan shroud 7 to fix the cylinder head a second time. After fixing, the worker can use a welding torch to perform welding repair work. When smoke is generated during welding, the suction assembly can be activated to centrally extract and remove the welding smoke. This achieves the goal of conveniently discharging the smoke generated during cylinder head welding repair, avoiding the problem of smoke affecting the worker's observation and causing tilting or displacement during welding. This device solves the problems mentioned in the background art.
