Referring to fig. 3, in some embodiments of the present invention, the foldable commodity shelf 100 further includes a box 170, and the box 170 is placed in the accommodating cavity 10 a. In this embodiment, four boxes 170 are placed in the foldable article holder 100, and through setting up the boxes 170, different articles can be classified, so that the user can find out an article quickly through the classified boxes 170 when needing to use the article.

In addition, the foldable article holder 100 according to the embodiment of the present invention can be used for placing articles, and the movable rod 112 is sleeved with a garbage bag, so that the foldable article holder 100 can be used as a garbage can, and the foldable article holder 100 according to the embodiment of the present invention has various uses.

A folding shelf 100 according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 6 as a specific embodiment. It is to be understood that the following description is illustrative only and is not intended to be in any way limiting.

As shown in fig. 1 to 6, the control device is preset with the relationship between the distance range and the unfolding degree of the foldable commodity shelf 100, the switch of the foldable commodity shelf 100 is turned on, after the user's hand is placed above the foldable commodity shelf 100, the first sensing device 161 senses the distance between the hand and the foldable commodity shelf 100, and the distance information is transmitted back to the control device, the control device judges which distance range the control device is in according to the distance information, finds out the expansion size of the bottom plate group 130 corresponding to the distance range, after expansion, a receiving chamber 10a having a certain capacity is formed, at which the user can place the article in the receiving chamber 10a, after the placement, the switch of the foldable shelf 100 is closed to prevent the user from moving the foldable shelf 100, the first sensing device 161 detects the distance between the user and the foldable rack 100, and then changes the size of the foldable rack 100 by mistake. After taking out article, when need not to use folding supporter 100, open folding supporter 100's switch, the hand is not placed in folding supporter 100's top, avoid first induction system 161 to sense the distance of user with folding supporter 100, and simultaneously, the pressure value in second induction system 162 response holding chamber 10a, and feed back pressure value signal to controlling means, controlling means control driver 122 action, make slider 121 upwards slide, folding bottom plate group 130, make whole folding supporter 100 fold, reduce the occupation in space. Meanwhile, each component of the foldable article holder 100 is detachable and convenient to transport after being detached.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
