    摘要： A cutting structure is provided for forming on the bent position of a flexible sheet. The cutting structure has two parallel cutting paths. Each of the cutting paths has a plurality of cutting sections adjacently arranged at intervals to each other. Each cutting section is of a linear shape to cut through the flexible sheet. The cutting sections on the cutting path are laterally offset with respect to the cutting sections on another cutting path. The two ends of the cutting sections of two parallel cutting paths are oppositely interlaced without connecting to each other. While the cutting structures are correspondingly formed on the bent positions of the flexible sheet to assist the curvature of the bent position, the flexible sheet can be formed into a stereoscopic contour.
