A connecting rod is pivotally connected to the inner end of the folding rod, so that the folding rod and the connecting rod can be spread and flattened, and the connecting rod can be rotated and folded into the receiving groove of the folding rod; and then the folding rod and the connecting rod A first rotating block and a second rotating block are respectively pivotally connected to the outer side of the rod, and the first rotating block and the second rotating block are respectively pivotally connected with the first connecting rod by the first shaft and the second shaft a second connecting rod, the first connecting rod and the second connecting rod are rotated inwardly or inflated and flattened; The first link system of the folding link set is respectively pivotally coupled with the two support frames of the first side frame group, and the second link system of the first and second folding link sets respectively and the second support frame of the central support frame group The first link system of the third and fourth folding link sets is pivotally coupled with the second support frame of the second side frame group, and the second link of the third and fourth folding link sets The system is respectively pivotally coupled with the two support frames of the central support frame group; and the first and second folding link sets are symmetrically arranged, and the third and fourth link sets are symmetrically arranged, and first And the two folding link sets are folded and folded into the horizontal storage slots provided by the first side frame group and the central support frame group, and the third and fourth folding link groups are foldable and folded to the second side frame group. In the horizontal storage groove provided with the central support frame group; by the above configuration, the utility model provides a foldable storage, convenient carrying, and high bearing capacity. Shelf. The mounting frame of the first aspect of the invention, wherein the first rotating block is provided with a sliding slot, and the first shaft is passed through the sliding slot and the first connecting rod and the second connecting rod. Pivot.
