A clamping plate 5 is provided inside the hole groove 4. After the mica sheet is placed in the through hole 3, the electromagnet 401 and the magnetic block 501 repel each other to push the clamping plate 5 to extend into the through hole 3 and clamp and fix the mica sheet penetrating to the height of the superimposed plate 2, and drive the clamped mica sheet to be screened out as the superimposed plate 2 rises and separates.
