[0045] Working principle: When using a welding device that is easy to adjust for boiler production, first start the motor 1102 to drive the rotation of the drive shaft 1103 connected to the output shaft of the motor 1102. Under the transmission connection of the bevel gear set 1105, the rotation of the drive shaft 1103 drives the synchronous rotation of the linkage shaft 1104, which is sleeved on the outer ring of the drive shaft 1103 and is connected to the drive through the bevel gear set 1105. At this time, the rotation directions of the drive shaft 1103 and the linkage shaft 1104 are opposite, so that the two linkage plates 1107 fixedly sleeved on the outer walls of the drive shaft 1103 and the linkage shaft 1104 drive the two arc covers 101 to move in opposite directions through the vertical rod 104 fixedly plugged with the linkage plate 1107.
