[0023] When welding the main board, high temperature melts the metal, so that the molten metal fuses together, and two or more metals are welded together, which has a higher bearing capacity. During the welding process, pungent gas will be generated due to high temperature welding. The gas is harmful gas, the main component of which is sulfur dioxide.

The outer ring of the clamping device 4 is located in the sliding groove 33 and is rotatably sleeved with a clamping plate 43.

The surface of the card plate 43 is provided with a strip groove, and a slide post 432 is fixedly installed between the inner walls of the strip groove.

The pressure block 48 is made of soft rubber material and has high friction.

[0026] By rotating the sleeve 42, the clamping device 4 is driven to rotate in the same direction, and the slide 431 drives the card plate 43 located on the outer ring of the clamping device 4 to slide. By adjusting the rotation direction of the sleeve 42, the clamping device 4 drives the card plate 43 to slide inward or outward. When the two card plates 43 slide inward at the same time, the outer side of the main board is clamped. If the main board is rectangular in shape and placed on the upper surface of the cross plate B3, the position of the slider 44 is moved inward from both ends of the card plate 43, and the main board is clamped using the plane of the card plate 43, so that one side of the slider 44 is aligned with the rectangular The plane of the card plate 43 is fitted with the side of the rectangular mainboard. If the mainboard is circular, slide the slider 44 to both ends of the card plate 43 so that the top of the slider 44 fits with the arc edge of the arc-shaped protrusion, and place the mainboard between the arc-shaped protrusions of the card plate 43 so that the arc surface of the arc-shaped protrusion fits better with the arc edge of the circular mainboard.

[0027] Working principle: By rotating the sleeve 42, the clamping device 4 is driven to rotate in the same direction, and the slide 431 drives the card plate 43 located at the outer ring of the clamping device 4 to slide. By adjusting the rotation direction of the sleeve 42, the clamping device 4 drives the card plate 43 to slide inward or outward. When the two card plates 43 slide inward at the same time, the outer side of the main board is clamped. If the main board is rectangular in shape, it is placed on the upper surface of the cross plate B3, and the position of the slider 44 is moved inward from the two ends of the card plate 43. The plane of the card plate 43 and one side of the slider 44 are used to fit the plane of the rectangular main board. If the main board is circular in shape, the slider 44 is slid toward the two ends of the card plate 43 so that the top of the slider 44 is matched with the arc edge of the arc protrusion, and the main board is placed between the arc protrusions of the card plate 43 so that the arc surface of the arc protrusion is more closely fitted with the arc edge of the circular main board. After the main board is clamped, the torsion block 47 is twisted and rotated to make the pressure block 48 moves downward to press against the upper surface of the mainboard to prevent the mainboard from shaking during the welding process, which has the effect of adapting to mainboards of different shapes. During the welding process, pungent gas will be generated due to high-temperature welding. The gas is harmful gas, the main component of which is sulfur dioxide. Long-term inhalation into the human body will cause harm to the human body. The mainboard is fixed to the upper surface of the horizontal plate B3 using the clamping device 4, and the interior of the liquid tank 7 is placed with acidic potassium permanganate. The fan 6 is started, and then the mainboard is welded. The smoke from the mainboard welding is absorbed by the suction hole of the suction block 5, enters the interior of the fan 6 through the circulation groove 34, and then blows the harmful gas into the interior of the reaction pot 8 through the exhaust pipe 62. The gas enters the potassium permanganate solution through the air vent 81. The potassium permanganate solution will undergo an oxidation-reduction reaction with harmful gases such as sulfur dioxide, so that the harmful gas is oxidized and reduced by potassium permanganate, which will not cause harm to the human body.
