When the first rotating rod 23 rotates, it can drive the auxiliary pulley 82 to rotate. When the auxiliary pulley 82 rotates, it can drive the main pulley 8 to rotate through the belt 81. When the main pulley 8 rotates, it can drive the second gear 72 to rotate. When the second gear 72 rotates, it can drive the second rack 7 to move, which in turn can drive the second cover plate 62 and the first cover plate 6 to move and close the storage box 13.

The first connecting column 61 and the second connecting column 63 cooperate to support the second rack 7. A motor 2 is provided; when the motor 2 starts, it drives the first rotating rod 23 to rotate. When the first rotating rod 23 rotates, it drives the first gear 43 to rotate. When the first gear 43 rotates, it drives the first rack 42 to move. When the first rack 42 moves, it drives the first support rod 33 to move. When the first support rod 33 moves, it drives the lifting plate 44 to move, thus allowing the bionic arm 45 to be moved into the storage box 13 for storage. This eliminates the need for manual movement of the bionic arm 45, making storage more convenient and facilitating protection of the bionic arm 45. A guide ring 31 is slidably connected to the guide rod 3, facilitating the guidance and limiting of the lifting plate 44. The first support ring 4 and the second support rod 41 cooperate to support the first rack 42.
