As another preferred version of the present utility model, described first ruler is or/and second ruler is provided with scale, the center of described through hole and the line between the axle center of connecting pin are parallel to the long limit of corresponding ruler, and the line between the zero graduation of the center of described through hole and the corresponding end of corresponding ruler is perpendicular to the long limit of corresponding ruler.
Than prior art, the utlity model has following beneficial effect:
1, rotation first ruler or second ruler, first ruler and second ruler are overlapped with the both sides for the treatment of angle measurement respectively, by being separately positioned on first ruler and second ruler and can measuring the number of degrees for the treatment of angle measurement easily through the angulation line in connecting pin axle center, it can be used for measuring any length of side, angle at any angle.
When 2, drawing the angle, first ruler and second ruler are adjusted to the angle of the required number of degrees, can draw the angle easily, simple to operate.
3, fixedly install enlarging lens at protractor, the protractor scale can be amplified, further facilitate angulation, draw the angle.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view after first ruler and second ruler overlap.
Wherein, 1 is first ruler, and 2 is second ruler, and 3 is protractor, and 4 is connecting pin, and 5 is angulation line a, and 6 is through hole, and 7 is enlarging lens, and 8 is angulation line b.
The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment.
Referring to Fig. 1 and Fig. 2: angle square comprises first ruler 1, second ruler 2, connecting pin 4 and is provided with the protractor 3 of scale, center, first ruler 1 and second ruler 2 that connecting pin 4 passes protractor 3 successively are fixed together protractor 3, first ruler 1 and second ruler 2, and the axle center of connecting pin 4 is the center of protractor 3.First ruler 1 or/and second ruler 2 can rotate around connecting pin 4 axle center.Protractor 3 also can rotate around connecting pin 4 axle center, can pass through the position of position adjustment amount hornwork 3 zero graduations of amount of spin hornwork 3.First ruler 1 and second ruler 2 are rectangle, and in the present embodiment, first ruler 1 and second ruler 2 are equal-sized rectangle, and protractor 3 is circular, circumferentially is equipped with scale along protractor 3, and the diameter of protractor 3 is not more than the width of ruler.Be equipped with the angulation line on first ruler 1 and second ruler 2, namely first ruler 1 is provided with angulation line b8, second ruler 2 is provided with angulation line a5, angulation line a5 and angulation line b8 all arrange along corresponding ruler length direction, and angulation line a5 and angulation line b8 be the axle center (being the center of throughput hornwork 5) by connecting pin 4 and parallel with the long limit of corresponding ruler all.During use, rotate first ruler 1 or second ruler 2, first ruler 1 and second ruler 2 are overlapped with the both sides for the treatment of angle measurement respectively, at this moment, the angulation line b8 that is parallel to the long limit of first ruler 1 be parallel to second ruler 2 and grow the angle that angle between the angulation line a5 on limits equals to treat angle measurement, can obtain treating the angle of angle measurement by the scale that directly reads angulation line a5 and the corresponding protractor 3 of angulation line b8, it can be used for measure any length of side, angle at any angle, can directly measure the angle greater than 180 degree.When drawing the angle, first ruler and second ruler are adjusted to the angle of the required number of degrees, can draw the angle easily, simple to operate.
