Abstract
The utility model discloses a multifunctional set square, in particular to a set square capable of measuring an angle. The multifunctional set square comprises a 45-degree right-angle set square, and is characterized in that an angle scale is drawn on the right angle of the 45-degree set square, the bevel edge of the 45-degree set square is provided with a length scale, and a hole is arranged at the lower part of the integer scale correspondingly. The right-angle position of the multifunctional set square is drawn with the angle scale, the bevel edge is provided with the length scale, and the hole is arranged at the lower part of the integer scale correspondingly, thereby the multifunctional set square measures the angle conveniently, can be used as a simple compass, and realizes the purposes for being multifunctional and being convenient to carry.
Description
Technical field
The utility model belongs to a kind of set square, particularly the set square that can take measurement of an angle.
Background technology
Set square is students in middle and primary schools' survey tools used in everyday, and normally used set square not energy equivalent hornwork takes measurement of an angle, and can not be used for picture circle, can not reach one-object-many-purposes, the purpose that is convenient for carrying.
The utility model content
The purpose of this utility model provides a kind of multifunctional triangle, and this multifunctional triangle can be worked as protractor and be taken measurement of an angle and replace compasses to be used for picture circle.
The technical solution of the utility model is that a kind of multifunctional triangle comprises 45 ° of right angle triangles, it is characterized in that: place, described 45 ° of right angle triangle right angles, drafting has angle index, on 45 ° of right angle triangle hypotenuses the length scale is arranged, and is corresponding porose below the integer scale.
Because place, multifunctional triangle right angle, drawing has angle index, can be used for easily taking measurement of an angle.
Since on the multifunctional triangle hypotenuse length scale is arranged, corresponding porose below the integer scale, can utilize two pencils, a pencil inserts the center of circle that fixes in the hole, and another pencil inserts and centers on center of circle rotation in another hole, replaces compasses to draw circle and picture arc.
The beneficial effects of the utility model are: because the place, multifunctional triangle right angle that the utility model provides, drafting has angle index, the length scale is arranged on the hypotenuse, corresponding porose below the integer scale, can take measurement of an angle easily and also can replace compasses to draw circle and picture arc, can reach one-object-many-purposes, the purpose that is convenient for carrying.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Among the figure, 1.45 ° of right angle triangles, 2. right angle, 3. angle index, 4. length scale, 5. hole.
The specific embodiment
The specific embodiment of the present utility model is, as shown in the figure:
Embodiment 1, and multifunctional triangle comprises 45 ° of right angle triangles 1, it is characterized in that: 2 places, described 45 ° of right angle triangle right angles, drawing to have on 3,45 ° of right angle triangle hypotenuses of angle index has length scale 4, correspondence porose 5 below the integer scale.
Claims (1)
