Plate storage device

The plate storage device comprises a supporting frame, superposition blocks are arranged on the two sides of the supporting frame, the superposition blocks are distributed on the upper side and the lower side of the supporting frame and comprise a bearing base and a lower fixing block, the structures of the superposition blocks on the two sides of the supporting frame are symmetrically distributed, an inserting block is arranged below the lower fixing block, and a cylindrical structure is arranged below the inserting block. Wherein a cylindrical groove is formed in the upper portion of the corresponding bearing seat, the inserting block is borne through the bearing seat, and a stopping block is arranged on the outer side of the inserting block. The inserting blocks are borne through the bearing bases, the stopping blocks are arranged on the outer sides of the inserting blocks, and the descending positions of the inserting blocks in the bearing bases are limited through the stopping blocks, so that plates plac
