Abstract
The utility model provides a pair of protractor compasses, which comprises a protractor and compasses, wherein a circular point of the protractor is fixed at an intersection part of a rotating arm and a supporting arm of the compasses; and the plane on which the protractor is located is parallel to the plane on which the rotating arm and the supporting arm are located. When the protractor compasses are used, a user can normally use the protractor to draw circular patterns after the rotating arm and the supporting arm of the compasses are separated; when the rotating arm and the supporting arm of the compasses are separated, angles of the two arms can be obtained on the protractor; and then corresponding angles can be drawn along the inner sides of the rotating arm and the supporting arm. By combining the protractor and the compasses, the protractor compasses have the advantages of simple structure, convenience, practicality, attractive appearance and comprehensive function, and can simultaneously fulfill the functions of the compasses and the protractor.
Description
Technical field
The utility model relates to a kind of drawing instrument, relates in particular to a kind of angulation compasses.
Background technology
Protractor is the drawing instrument that usually uses in people's study and work, and still, the compasses function ratio is more single at present; Can only draw circular pattern; Have no idea to bring into play other functions, in the study geometric knowledge, need to draw, measure various angles; Still need prepare protractor separately this moment, very trouble.In order to address the above problem, we provide a kind of new-type compasses that take measurement of an angle.
The utility model content
In order to achieve the above object; The utility model angulation compasses; Comprise protractor and compasses, the round dot place of described angulation is fixed on the turning arm of compasses and the infall of support arm, the plane, place of described protractor and turning arm, support arm place plane parallel; Compasses turning arm, support arm are vertical with the base of protractor when merging, and the arc surface of protractor is towards compasses syringe needle direction.
Described angulation compasses in use; After the turning arm of compasses and support arm open; User normally use amount hornwork draws circular pattern; When the turning arm of compasses, when support arm separates, can obtain the angle of two arms from protractor, can draw respective angles along the inboard of turning arm and support arm then.
The fixed support end of described compasses support arm is provided with the rubber fixture.
Compasses and protractor are combined, have simple in structure, convenient and practical, good looking appearance, complete function, can bring into play the function of compasses and protractor simultaneously.
And the support end of support arm is set to the rubber fixture, skidding can not occur.
Description of drawings
Fig. 1 is the structural representation of the utility model angulation compasses;
Reference numeral
1, protractor; 2, turning arm; 3, support arm.
The specific embodiment
Below in conjunction with accompanying drawing the utility model angulation compasses are carried out detailed explanation.
The utility model discloses a kind of angulation compasses; Comprise protractor 1 and compasses; The round dot place of described angulation 1 is fixed on the turning arm 2 of compasses and the infall of support arm 3; The plane, place of described protractor 1 and turning arm 2, support arm 3 place plane parallel, compasses turning arm 2, support arm 3 are vertical with the base of protractor 1 when merging, and the arc surface of protractor 1 is towards compasses syringe needle direction.
Described angulation compasses in use; After the turning arm of compasses and support arm open; User normally use amount hornwork draws circular pattern; When the turning arm of compasses, when support arm separates, can obtain the angle of two arms from protractor, can draw respective angles along the inboard of turning arm and support arm then.
The fixed support end of described compasses support arm is provided with the rubber fixture.
Compasses and protractor are combined, have simple in structure, convenient and practical, good looking appearance, complete function, can bring into play the function of compasses and protractor simultaneously.
And the support end of support arm is set to the rubber fixture, skidding can not occur.
