CURVE TRACING FLEXIBLE RULER AND CURVE DRAWING DEVICE

摘要

A curve tracing flexible ruler (100) and a curve tracing device. The curve tracing flexible ruler (100) comprises a flexible ruler body (10) which is set into a structure with the strength gradually weakened from two ends to the middle, so that the strength of the curve tracing flexible ruler (100) is gradually weakened from two ends to the middle; the strength of the curve tracing flexible ruler (100) is gradually weakened from two ends to the middle, thus, positioning is performed at the middle position to form a vertex of a curve; when the positions on the two sides of the middle position are correspondingly positioned, the strength of the position closer to the middle position becomes small, design finalizing by a positioning point is easier, the arrangement that the curvature becomes large due to bending is achieved, and then the problem that when a flexible ruler is used for making a curve by means of a specific point, precision is low is solved.
