The front end of the spring 55 is welded to the inner cavity of the T-shaped slide groove 52. Through the setting of the locking component 5, the limit card 53 and the limit card slot 54 are used in coordination to limit and lock the wind shield 2. At the same time, under the elastic force of the spring 55, the limit card 53 is pushed, so that the limit card 53 can actively engage with the limit card slot 54, which plays a limit locking role on the wind shield 2. The rear side of the top of the welding machine 1 is fixedly installed There is a push switch 6, LED lights 7 are fixedly installed on both sides of the inner cavity of the wind shield 2, a rotating assembly 8 is arranged on the rear side of the top of the welding machine 1, and the rotating assembly 8 includes a fixed seat 81 fixedly connected to the rear side of the top of the welding machine 1, a rotating member 82 is arranged between the two fixed seats 81, the front side of the rotating member 82 is fixedly connected to the wind shield 2, and rotating columns 83 are fixedly connected on both sides of the rotating member 82, and the rotating column 83 is rotatably connected to the inner cavity of the fixed seat 81. A torsion spring 84 is sleeved on the surface of the rotating column 83, and one end of the torsion spring 84 is welded to the rotating member 82. The other end of the spring 84 is welded to the fixed seat 81. Through the setting of the rotating component 8, the fixed seat 81, the rotating column 83 and the rotating part 82 are used in coordination, so that the wind shield 2 can rotate according to a predetermined trajectory, so that the sealing gasket 3 can be accurately engaged in the inner cavity of the sealing groove 4 to seal the interior of the wind shield 2.
