[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A protractor comprises a protractor and a scale, the protractor comprising a No. 1 protractor and a No. 2 protractor, the No. 2 protractor being fixedly arranged on the right side of the No. 1 protractor and forming an integral structure with the No. 1 protractor, the scale comprising a No. 1 scale and a No. 2 scale, the No. 1 scale being hinged to the No. 1 protractor and the hinge being located at the radial center of the No. 1 protractor, a No. 1 needle shaft being provided at the rear end of the No. 1 scale, the No. 1 needle shaft and the No. 1 scale forming an integral structure, the No. 2 scale being hinged to the No. 2 protractor and the hinge being located at the radial center of the No. 2 protractor, the No. 2 needle shaft being fixedly provided at the top end of the No. 2 scale, the No. 2 needle shaft and the No. 2 scale forming an integral structure.

[0006] The beneficial effect of the present invention is that: the design provides a No. 1 scale and a No. 2 scale hingedly connected to the No. 1 angle ruler and the No. 2 angle ruler respectively, so that the No. 1 scale and the No. 2 scale can perform rotational measurement of any angle on the No. 1 angle ruler and the No. 2 angle ruler, and different measuring methods can be used for different measuring angles, so that the device can accurately measure any angle.

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] like Figures 1 to 3 As shown, an angle ruler includes an angle ruler and a scale, the angle ruler includes a No. 1 angle ruler 1 and a No. 2 angle ruler 2, the No. 2 angle ruler 2 is fixedly arranged on the right side of the No. 1 angle ruler 1 and is an integrally formed structure with the No. 1 angle ruler 1, the scale includes a No. 1 scale ruler 3 and a No. 2 scale ruler 4, the rear portion of the No. 1 scale ruler 3 is hinged to the No. 1 angle ruler 1 and the hinge is located at the radial center of the No. 1 angle ruler 1, so that the front end of the No. 1 scale ruler 3 can be rotated at any angle around the radial center of the No. 1 angle ruler 1 to measure any angle, and the rear end of the No. 1 scale ruler 3 is provided with a No. 1 needle shaft, and the No. 1 needle shaft and the No. 1 scale ruler are an integrally formed structure. The integrally formed structure enables the No. 1 scale 1 to drive the No. 1 needle shaft to point to the corresponding degree value on the No. 1 angle ruler 1 when rotating to measure the angle. The center of the No. 2 scale 4 is hinged to the No. 2 angle ruler 2, and the hinge is located at the radial center of the No. 2 angle ruler 2, so that the No. 2 scale 4 can rotate around the center of the No. 2 angle ruler 2 to measure any angle. The No. 2 needle shaft is fixed at the top center of the No. 2 scale 4. The No. 2 needle shaft and the No. 2 scale 4 are an integrally formed structure. When the No. 2 scale 4 is rotated for measurement, the No. 2 needle shaft can point to the corresponding degree value on the No. 2 angle ruler 2.

[0015] During use, when the measured angle is greater than or equal to 90°, use the bottom edge of the No. 1 angle ruler 1 to align with one side of the angle to be measured, rotate the No. 1 scale 3 so that its scale edge aligns with the other side of the angle to be measured, and at this time record the degree value on the No. 1 angle ruler 1 pointed by the No. 1 needle axis, and subtract the degree value indicated by the No. 1 needle axis from 180°. The resulting degree value is the degree value of the measured angle; when the measured angle is less than 90°, rotate the No. 1 scale ruler 3 so that the scale edge of the No. 1 scale ruler 3 aligns with one side of the angle to be measured, and rotate the No. 2 scale ruler 4 so that its bottom edge aligns with the other side of the angle to be measured. At this time, the sum of the degree value indicated by the No. 1 needle axis and the degree value indicated by the No. 2 needle axis is the degree value of the angle to be measured.

[0016] The design of the present invention is that the first scale and the second scale are respectively provided with a hinged scale on the first and second angle rulers, so that the first scale and the second scale can perform rotational measurement of any angle on the first and second angle rulers, and different measuring methods can be used for different measuring angles, so that the device can accurately measure any angle.

[0017] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
