When one of the material plates 17 is transferred and the material plates 17 on both sides are not transferred, the sealing layer 18 between the material plate 17 and the material plates 17 on both sides is stretched and compressed, after the material plates 17 are transferred in place, the positioning rod 20 positioned at the rear of the movement direction of the material plates 17 blocks the material plates 17, the material plates 17 are prevented from being reset under the pulling of the sealing layer 18, meanwhile, the piezoelectric springs 32 are electrified, the tooth blocks 31 are disengaged from the tooth grooves 26, the movable ends of the positioning rods 20 facing the through holes are inserted into the through holes, and the positions of the material plates 17 are fixed again.
