Abstract
The utility model discloses a combined suite ruler, belonging to stationery. The combined suite ruler is used for mainly solving the problem that the traditional rulers are mutually independent, can not be carried conveniently and are easy to lose. The combined suite ruler is characterized by comprising an isosceles right-angle set square and a special right-angle set square; the isosceles right-angle set square and the special right-angle set square are connected with each other at a corner by a rotating shaft; the special right-angle set square is provided with a protractor which is provided with a gap; and the edge of the gap is provided with scales of the protractor. Compared with the prior art, without affecting the use, the functions of various rulers used frequently at ordinary times are combined; therefore, the suite ruler can be carried more conveniently and the unnecessary loss of buying a whole suite after one ruler is lost is prevented.
Description
Technical field
The utility model relates to a kind of stationery, specifically a kind of combination cover chi.
Background technology
Ruler all is the instrument of an indispensability in each student's learning life, and the major part of using is separated now, is inconvenient to carry and lose easily, existing set square mostly is complete sale, if lose one of them, just need to buy a cover again, cause unnecessary loss to people.
The utility model content
The purpose of this utility model is to provide a kind of combination cover chi, and the function of the multiple ruler that this ruler will be used always at ordinary times is combined, carries convenient.
The technical scheme in the invention for solving the technical problem is: this kind combination cover chi, it is characterized in that, comprise an isosceles right angle triangle and a special right angle triangle, described isosceles right angle triangle and special right angle triangle link together by rotating shaft at place, an angle, on special right angle triangle, be provided with a protractor, described protractor forms a breach, is provided with the scale of protractor in the edge of breach.
Two acute angle angles of described special right angle triangle are respectively 30 ° and 60 °.
The beneficial effects of the utility model are: under the prerequisite that does not influence use that the function of multiple ruler commonly used at ordinary times is combined, carry conveniently, and prevent loss one and will buy a whole set of again and cause unnecessary loss to people.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 special right angle triangle; 2 isosceles right angle triangles; 3 protractors.
The specific embodiment
As shown in Figure 1.Combination cover chi, comprise an isosceles right angle triangle 2 and a special right angle triangle 1, described isosceles right angle triangle 2 and special right angle triangle 1 link together by rotating shaft at place, an angle, on special right angle triangle 1, be provided with a protractor 3, described protractor 3 forms a breach, is provided with the scale of protractor 3 in the edge of breach.
1 two acute angle angles of described special right angle triangle are respectively 30 ° and 60 °.Be the most frequently used elongated right angled triangle of people.
During use, special right angle triangle 1 and isosceles right angle triangle 2 can relatively rotate, and the use of both and protractor 3 is independent of each other.Compared with prior art, the utility model is under the prerequisite that does not influence use, and the function of multiple ruler commonly used at ordinary times is combined, carries conveniently, prevents loss one and will buy a whole set of again and cause unnecessary loss to people.
