At the same time, during the movement of the push plate 63, the push plate 63 moves and drives the elastic The elastic telescopic rod 64 moves, and the movement of the elastic telescopic rod 64 drives the rotating wheel 65 to move. The rotating wheel 65 will contact the protrusion 67 during the movement, and generate squeezing force on the elastic telescopic rod 64. After passing over the protrusion 67, the elastic telescopic rod 64 is reset, and it will knock on the leakage plate 66 to make the leakage plate 66 vibrate, so that the welding slag remaining on the leakage plate 66 can be shaken off, thereby enhancing the cleaning effect of the welding slag and avoiding excessive accumulation of welding slag on the top of the leakage plate 66, which will cause the welding slag to easily adhere to the weldment during welding, causing spots on the surface of the weldment and affecting the yield rate of the weldment.
