| Zusammenfassung: | The utility model provides a folding type angle ruler, which can be used for measuring lengths and angles, as well as drawing straight lines and angle lines. The folding type angle ruler consists of an angle measuring shaft and standard sections, wherein the angle measuring shaft passes through shaft holes in the standard sections to connect the two standard sections; under the action of external force, the standard sections can rotate around the angle measuring shaft to form any included angle. The folding type angle ruler has the beneficial effects that basic functions of an ordinary straightedge are improved, the measurement range of the straight ruler can be widened, functions of measuring the angles and drawing the angle lines are added to the angle ruler, the structure is simple, and the storage is convenient. |
