Abstract
The utility model relates to a folding angle ruler, belongs to stationery, and mainly solves the problem that a triangle graduated scale and an angle gauge have a single function. The angle ruler comprises an angle gauge, a rotating shaft and a triangle graduated scale, wherein a bottom edge of the angle gauge is movably hinged with a bevel edge of the triangle graduated scale through the rotating shaft. The folding angle ruler integrates the triangle graduated scale with the angle gauge, and the problem that the integrated ruler has overlarge volume and is difficult to use is solved through a folding structure; and the folding angle ruler has the functions of measuring angles and drawing straight lines, and is convenient to use and easy to carry.
Description
Technical field
The utility model relates to a kind of stationery, specifically a kind of trigonometric scale.
Background technology
Trigonometric scale and protractor all are people's one of commonly used stationery in study and work.But existing trigonometric scale and protractor are independent existence, need during drawing often to switch to use this stationery of two kinds, use and carry all inconveniently, cause trouble to the user.
The utility model content
The purpose of this utility model is to provide a kind of folding angle square, mainly solves the problem of trigonometric scale and protractor function singleness, and this folding angle square is incorporated into trigonometric scale with protractor, reduces the volume when placing, and convenient the use is easy to carry about with one.
The technical scheme in the invention for solving the technical problem is: folding angle square, and its structure comprises protractor, rotating shaft and trigonometric scale, the base of described protractor is movably hinged by the hypotenuse of rotating shaft and trigonometric scale.
The beneficial effects of the utility model are: this folding angle square is incorporated into trigonometric scale with protractor, the excessive not wield problem of ruler volume after using foldable structure to avoid integrating simultaneously; Use this folding angle square can either realize the function that takes measurement of an angle, can realize drawing the function of straight line again, easy to use, be easy to carry about with one.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 protractor, 2 rotating shafts, 3 trigonometric scales.
The specific embodiment
As shown in Figure 1.Folding angle square, its structure comprises protractor 1, rotating shaft 2 and trigonometric scale 3, the base of described protractor 1 is movably hinged by the hypotenuse of rotating shaft 2 with trigonometric scale 3.During use, protractor 1 and trigonometric scale 3 paved to use on the table; When depositing, trigonometric scale 3 is rotated along rotating shaft 2, dwindle the volume of ruler, be convenient to deposit; Should trigonometric scale 3 be incorporated into folding angle square the excessive not wield problem of ruler volume after using foldable structure to avoid integrating simultaneously with protractor 1; Use this folding angle square can either realize the function that takes measurement of an angle, can realize drawing the function of straight line again, use, easy to carry.
Claims (1)
