Abstract
The utility model relates to a novel coordinate tracing ruler. The novel coordinate tracing ruler comprises an X coordinate axis (10), a Y coordinate axis (20) and a tracing ruler body (30). The X coordinate axis (10) is perpendicular to the Y coordinate axis (20). The tracing ruler body (30) is composed of two straight boards (301) which are perpendicular to each other. The two straight boards (301) are perpendicularly inserted into a middle interlayer of the X coordinate axis (10) and a middle interlayer of the Y coordinate axis (20) respectively. The middle interlayer of the X coordinate axis (10) and the middle interlayer of the Y coordinate axis (20) are provided with a groove a (101) and a groove b (201) respectively. The two straight boards (301) are provided with a groove c (302) and a groove d (303) respectively.
