Structure for simply forming into three-dimensional ornament by sheet

The utility model provides a structure for simply forming into a three-dimensional ornament by a sheet, which is particularly used for cutting a plurality of sheet bodies which can be distorted to be bent on a flexible plane main sheet in a peripheral radiation manner by taking a central points as the reference. At least one connection part is arranged between each sheet body and the flexible plane main sheet, the same or different floral patterns are cut on each sheet body, each floral design comprises a floral pattern which can be outwards bended and is three-dimensional, buckling ends are respectively formed at two ends of each sheet, close to the periphery of the flexible plane main sheet, the two buckling ends of each sheet can be outwards pulled and buckled with each other under each peripheral connection part of the periphery of the flexible plane main sheet, and each sheet body naturally forms into corresponding arc due to the pull force among the sheets after two buckling ends of each sheet body are
