The first sheet body has a first block, a second block, a third block, a fourth block, a fifth block and a sixth block. The first block is in a trapezoidal shape and the second block is in a trapezoidal shape and its upper bottom edge is connected to an upper bottom edge of the first block to define an engaged status. The third block is in a triangular shape and connected to one of the side edges of the first block, and the fourth block is in a triangular shape and connected to the other side edge of the first block and configured to be symmetrical to the second block. The fifth block is in a trapezoidal shape and its side edge is connected to one of the side edges of the second block, and the sixth block is in a trapezoidal shape and its side edge is connected to the other side edge of the second block and configured to be symmetrical to the fifth block. The arrangement of the first to sixth blocks allows the first sheet body to from a contour line of a rectangular sheet structure. The edges of the first to sixth blocks can be folded into a shelf. The second sheet body has an area smaller than the first sheet body, and a side of the first sheet body is partially disconnected from the first sheet body. Therefore, users can form the shelf by folding to facilitate the application of placing objects. When the shelf is not in use, the shelf can be maintained as a sheet body to facilitate storage and carrying. ## Claims ### Claim 1 A folding shelf, comprising: a first sheet body, having a first block, a second block, a third block, a fourth block, a fifth block and a sixth block, and the first block being in a trapezoidal shape, and the second block being in a trapezoidal shape and having an upper bottom edge coupled to an upper bottom edge of the first block to define an engaged status; the third block being in a triangular shape and coupled to one of two side edges of the first block, and the fourth block being in a triangular shape and coupled to another side edge of the first block and configured to be symmetrical to the third block; the fifth block being in a trapezoidal shape and having a side edge coupled to one of two side edges of the second block, and the sixth block being in a trapezoidal shape and having a side edge coupled to another side edge of the second block and configured to be symmetrical to the fifth block; wherein the first block, the second block, the third block, the fourth block, the fifth block and the sixth block are arranged, such that the first sheet body forms a contour line of a rectangular sheet structure, and edges of the first block, the second block, the third block, the fourth block, the fifth block and the sixth block are folded to define a shelf status; and a second sheet body, having an area smaller than the first sheet body, and disposed on a side of the first sheet body, and situated in a status of being partially coupled to the first sheet body. ### Claim 2 (depends on 1) The folding shelf as claimed in claim 1, wherein the second sheet body is coupled to the second block of the first sheet body. ### Claim 3 (depends on 2) The folding shelf as claimed in claim 2, wherein the second sheet body has at least one stop portion. ### Claim 4 (depends on 3) The folding shelf as claimed in claim 3, wherein the second sheet body has a card slot relative to a side coupled to the first sheet body. ### Claim 5 (depends on 4) The folding shelf as claimed in claim 4, wherein the stop portion is disposed on a side of the second sheet body which is coupled to the first sheet body. ### Claim 6 (depends on 2) The folding shelf as claimed in claim 2, wherein the second sheet body has a carrying surface which is a non-slip surface. ### Claim 7 (depends on 1) The folding shelf as claimed in claim 1, further comprising a plurality of magnetic elements, and the magnetic elements being installed to the third block and the fourth block respectively.
