A tooth engaging structure 123 is disposed between the two brackets 121, wherein one of the brackets 121 rotates relative to the fixed structure 11, and the tooth engaging structure 123 drives the other bracket 121 to rotate relative to the fixed structure 11 in an opposite direction. The article placing device 12 has a folding position and an unfolding position, wherein the two brackets 121 are in a horizontal state in the folding position, and the two brackets 121 form a certain included angle to place articles on the two brackets 121 in the unfolding position. The fixing structure 11 includes a first limiting portion 112 and a second limiting portion 113, the article placing device 12 can be abutted against the first limiting portion 112 or the second limiting portion 113, when the article placing device 12 is abutted against the first limiting portion 112, the two brackets 121 are in the folded position, and when the article placing device 12 is abutted against the second limiting portion 113, the two brackets 121 are in the unfolded position.

Further, an elastic member 13 is disposed between the article holding device 12 and the fixing structure 11, and the elastic member 13 provides an elastic force for rotating the two brackets 121 from the unfolded position to the folded position. When the article placing device is used, one support 121 in the folding position is pulled to rotate, the tooth meshing structure 123 drives the other support 121 to rotate in the opposite direction, the elastic element 13 stores energy, when the article placing device 12 is abutted to the second limiting portion 113, the two supports 121 cannot continue to rotate along the original direction, the two supports 121 reach the unfolding position, an article is placed on the supports 121 at the moment, elastic reset of the elastic element 13 is prevented under the action of gravity of the article, the article is taken down at the moment, the elastic force of the elastic element 13 drives the supports 121 to rotate back to the folding position, and when the article placing device 12 is abutted to the first limiting portion 112, the two supports 121 reach the folding position and cannot continue to rotate.

Further, the storage device 12 further includes a rotating member 122, and each of the brackets 121 is fixedly connected to the rotating member 122 and pivotally connected to the fixed structure 11 through the rotating member 122.
