Abstract
The utility model relates to a set square, in particular to a multifunctional set square which comprises a protractor. The multifunctional set square is characterized in that a semi circle is reserved in the set square, angles are marked, a straight rotating rod is installed at the center of the semi circle, and the angle of the rotating rod can be adjusted casually. The multifunctional set square has the advantages that the set square and the protractor are combined ingeniously so that the set square has multiple functions, the protractor can be used for measuring angles, any angles within 180 degrees can be directly drawn by the straight rotating rod, and the multifunctional set square is convenient to use and practical.
Description
(1) technical field
The utility model relates to a kind of set square, particularly a kind of multifunctional triangle.
(2) background technology
Many primary and secondary students want to draw exactly the angle of non-special number of degrees, often want utilization hornwork and set square to draw back and forth, measure and just can draw several times, and have brought inconvenience for student's study.
(3) summary of the invention
The utility model provides a kind of multifunctional triangle in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following scheme:
A kind of multifunctional triangle comprises protractor, so its special character exists: reserve semicircle in set square, put on angle and at its semicircle circle centre position installation bull stick always, can adjust angle arbitrarily.
Therefore, the beneficial effects of the utility model are: this multifunctional triangle, with set square and the ingenious combination of protractor, reach one-object-many-purposes, and protractor not only can take measurement of an angle and can also utilize straight bull stick directly to draw less than any angle of 180 degree, and is convenient and practical.
(4) description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is structural representation of the present utility model.
1 set square among the figure, 2 protractors, 3 straight bull sticks free to rotate.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This fact Example comprises protractor 2, it is characterized in that: reserve semicircle in set square, put on angle and at its semicircle circle centre position installation bull stick 3 always, can adjust angle arbitrarily.
Utilize this multifunctional triangle, both can draw straight line, amount length with set square 1, also can measure the size at a certain angle with protractor 2, can also directly draw less than any angle of 180 degree with straight bull stick 3 simultaneously.
