Abstract
The utility model provides a protractor with a ruler which is connected with a ruler at the side of the body thereof; the body of the protractor is provided with an angle intersection orifice; and the body is further provided with a small semicircular hollow strip. Through above setting, the protractor measures the length, the size and the angle; the angle intersection orifice is convenient to measure the angle and taken as a vertex to locate; thus, the angle is measured accurately.
Description
Technical field
The utility model relates to a kind of surveying and mapping tool, a kind of specifically protractor with ruler.
Background technology
Common protractor can only use as the certain angle of measuring and calculating, draws straight line and measuring and calculating length needs use ruler in addition, and simultaneously, traditional protractor can only indicate the angle of certain semicircle distance, and is then can't disposable accurately sign after less than the protractor semicircle clear.
Summary of the invention
The utility model provides a kind of protractor with ruler, has the advantages that to can be used as that ruler uses and can favourable accurate sign angle.。
The utility model comprises the protractor body, and the technical scheme that is adopted is: described protractor is connected with a ruler at the side of body.
The body of protractor is provided with angular cross point eyelet.
On body, also be provided with a small semicircle hollow out bar.
The beneficial effects of the utility model are: by above-mentioned setting, make it protractor and have and can calculate length and big low-angle multiple function of use, when its angular cross point eyelet can conveniently be calculated angle, locate as the summit, make angle meter more accurate.
