The slag absorption plate 36 is reset due to the elastic force of the torsion spring 35, so that the semicircular groove 33 is closed, and the driving motor 48 is started. The second gear 50 on the output shaft 49 of the driving motor 48 rotates, so that the first gear 44 drives the rotating shaft 43 to rotate, and the annular iron absorption block 45 on the rotating shaft 43 rotates, so that the metal chips adsorbed on the outer wall of the annular iron absorption block 45 fall into the arc slag bucket 51.

[0048] In another embodiment, if Fig.12 and Fig.13As shown, the slag suction plate 36 arranged at the semicircular groove 33 is L-shaped, and the slag suction plate 36 is movably connected to the drain pipe 28. When the top of the slag suction plate 36 is subjected to a vertical downward force, the long section can move inside the drain pipe 28 and be in a vertical direction, which can slow down the flow rate of the cutting fluid to a greater extent and absorb the slag in the cutting fluid. When there is no force, it automatically resets and closes the semicircular groove 33 to prevent impurities from entering the drain pipe 28.
