Abstract
The utility model relates to a combination ruler, which comprises an annular circle (1), a dividing ruler (2), a concave-convex interface groove (3), a scale mark (4) and a hollow circle (5), and is characterized in that the hollow circle (5) is arranged inside the annular circle (1); a circle of gap is formed on the circumference of the hollow circle (5); the dividing ruler (2) is embedded into the gap of the hollow circle (5); the concave-convex interface groove (3) is formed at the lower end of the annular circle (1); and the scale mark is positioned on the annular circle (1). The combination ruler can be combined to form an angle gauge with the dividing ruler and also can be disassembled to form the dividing ruler and a circular ring, so that the combination ruler is convenient to use.
Description
Technical field
The utility model relates to a kind of combination ruler.
Background technology
General ruler can not split combination, when the student maps, needs sometimes will draw semicircle simultaneously and measure with rule, and general ruler does not possess the function of picture semicircle, and can not make up fractionation, and is convenient inadequately during mapping.
Summary of the invention
