Abstract
The utility model relates to a multifunctional protractor, wherein one end of the multifunctional protractor is a semicircle, the other end of the multifunctional protractor is a square, the bottom side of the semicircle overlaps with one side of the square, the diameter of the semicircle is equal to the side length of the square, the semicircle extends towards the square to form a full circle, a hollow area is outward arranged in the full circle at the position of the middle portion of the inner circumference of the square, scales are engraved on the full circle, and the coordinate axis with scales is arranged on the square. The multifunctional protractor has the advantages of being capable of substituting for a set square, a ruler, a protractor, a number axis, a coordinate paper and the like, drawing various graphs and solving the problem that a drawing tool is simplex 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 singleness of the drawing instruments such as the set square that present student uses, protractor in order to satisfy the drawing requirement, can be effective just often need a plurality of drawing instruments to be combined with, and 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 the coincidence of foursquare one side, and the diameter of semicircle equals the foursquare length of side, described semicircle extends into full circle to square, full circle outwards is provided with a hollow area at the pars intermedia of square inner periphery, is carved with angle on the described full circle, and described square is provided with the reference axis with scale.
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.
