When the movable rod 24 is in contact with the right side of the inner cavity of the screening box 1 under the action of movement, the movable rod 24 is pushed by the continuous movement of the movable frame 9. The plastic push plate 23 is gradually away from the magnetic plate 25, thereby reducing the magnetic force of the magnetic plate 25 on the scrap metal sheet contacted by the left side of the plastic push plate 23, and causing the scrap metal sheet to fall into the interior of the collection box 17 for centralized collection, thereby greatly facilitating the subsequent cleaning work of the personnel.
