[0026] When the present utility model is in use: The main structure of the shelf includes a base 1. A first groove 10 is opened inside the base 1. The first groove 10 can provide an installation space for other components. A servo motor 11 is fixedly connected inside the first groove 10. The output end of the servo motor 11 is fixedly connected with a first gear 12. The outer wall of the first gear 12 is meshed with another second gear 13. A bidirectional threaded rod 15 is fixedly connected to the middle of the second gear 13. Clamping plates 17 are threadedly connected to both the left and right sides of the bidirectional threaded rod 15. By starting the servo motor 11 to drive the first gear 12 to rotate, at this time the first gear 12 drives the second gear 13 to rotate together. When the second gear 13 rotates, it drives the bidirectional threaded rod 15 to rotate. At this time, the left and right ends of the bidirectional threaded rod 15 are connected with clamping plates 17. The clamping plates 17 are fixedly connected to the U-shaped plates 2. With the rotation of the bidirectional threaded rod 15, it drives the clamping plates 17 and the U-shaped plates 2 to move.
