[0048] Worm gear 402: The outer surface of the worm gear 402 and the lower surface of the tooth plate 401 are in a mutually meshing relationship;

[0049] Support rod 403: The front end of the support rod 403 is fixedly connected to the rear surface of the worm gear 402, and the rear end of the support rod 403 is rotatably connected to the inner wall of the "V"-shaped support plate 301 through a rotating shaft.

[0050] The above solution is adopted: the worm gear 402 rotates with the support rod 403 as the rotation center, and the worm gear 402 can engage with the lower surface of the tooth plate 401, so that the tooth plate 401 moves to the opposite side, and the tooth plate 401 drives the clamping plate 304 to move to the opposite side along the sliding groove 302 through the sliding block 303. The clamping plate 304 limits and fixes the books on the outer surface of the "V"-shaped support plate 301 to prevent the books from shifting left and right during the up and down movement. Then, the books are locked by the thread locking mechanism 2.
