Abstract
The utility model relates to a multifunctional protractor. One end of the multifunctional protractor is a semi-circle, and the other end of the multifunctional protractor is a quadrate. A bottom side of the semi-circle and one side of the quadrate coincide, the diameter of the semi-circle is equal to the length of the side of the quadrate, angles are engraved on the semi-circle, and coordinate axes which are mutually perpendicular are engraved on the quadrate. The multifunctional protractor can replace a set square, a ruler, a protractor, a number axis, coordinate paper and the like, draws various graphs, and solves the problem that a drawing tool is single in function.
Description
Technical field
The utility model relates to a kind of drawing instrument, is specifically related to a kind of multi-function protractor.
Background technology
The function singlenesses such as the set square that present student uses, protractor in order to satisfy the drawing requirement, often need a large amount of instruments, carry very inconvenient.
Summary of the invention
In order to solve above-mentioned drawing instrument function singleness, carry inconvenient problem, the utility model provides a kind of multi-function protractor.
The technical solution of the utility model is as follows:
A kind of multi-function protractor, one end of described multi-function protractor is semicircle, the other end is a square, its special feature is, the base of described semicircle and foursquare one side overlap, the diameter of semicircle equals the foursquare length of side, is carved with angle on the described semicircle, is carved with orthogonal reference axis on the described square.
Further, the material of described multi-function protractor is transparent plastic.
The multi-function protractor that the utility model provides can replace set square, ruler, protractor, number axis, graph paper etc., draws multiple figure, has overcome the problem of drawing instrument function singleness.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
