When the box cover is in work, when the second magnet is installed, the blocking block on the second magnet is embedded into the fifth groove, so that the end part of the blocking block extends into the area above the box cover; therefore, when the cutting fluid flows on the upper surface of the box cover, the flowing cutting fluid is continuously hindered by the blocking block, so that the flow rate of the cutting fluid is reduced, the flowing time of the cutting fluid on the upper surface of the box cover is prolonged, and the iron chips remained in the cutting fluid are further adsorbed to the gap of the blocking block on the upper surface of the box cover, so that the cutting fluid is further purified.
Preferably, a layer of rubber film is pasted on the upper surface of the box cover, the rubber film is in a tight state, and the rubber film is in close contact with the end part of the blocking block.
When the cutting tool works, the rubber film is adhered to the upper surface of the box cover, and the flowing cutting fluid is in contact with the upper surface of the rubber film but not in direct contact with the block, so that the problem that the surface of the block is difficult to clean due to the fact that the cutting fluid is attached to the upper surface of the block is avoided; when cleaing away iron fillings, only need pull down the rubber membrane of pasting, can effectively clear away iron fillings, more change new rubber membrane afterwards, can put into use the miscellaneous box of collection rapidly for maintainer clearance iron fillings are more convenient, have reduced the time of maintainer and cutting fluid contact.

when the cutting fluid flows on the upper surface of the box cover 532, the iron filings remained in the cutting fluid are attached to the upper surface of the box cover 532 under the action of magnetic adsorption through the adsorption action of the four grooves 535, so that the iron filings in the cutting fluid are further removed; the scrap iron is uniformly distributed on the upper surface of the box cover 532 through the adsorption effect of the second magnet 536, so that the scrap iron is prevented from being accumulated near the filter screen 52 under the impact effect of flowing cutting fluid, and the cutting fluid is prevented from normally passing through the filter screen 52; in addition, through the adsorption of No. two magnet 536 to the iron fillings on lid 532 for iron fillings are fixed on lid 532, thereby guarantee dismantling lid 532 in-process, and the iron fillings that pile up on lid 532 remain stable, only need take out No. two magnet 536 at last, can easily effectively clear away the iron fillings that pile up on lid 532, and it is more convenient to operate.
