Abstract
A rapid angle drawing device is provided, which is an angle drawing device for rapidly drawing a desired angle, wherein ends of two straight rulers (2) are connected with the central point of an angle gauge (1) via a rotating shaft (3). When drawing an angle, a user utilizes either of straight rulers as one edge of the angle, measures the desired angle by using the angle gauge, keeps the other straight ruler at the other edge of the angle, and finally draws lines along the two straight rulers, the two lines defining the desired angle. The rapid angle drawing device has the advantages of simple structure, easy use, and rapid and accurate drawing of various angles.
Description
Technical field
The utility model relates to a kind of angle drawing device at required angle that can draw fast.
Background technology
Now as will draw the angle, except that right angle, 60 °, 30 ° angle can be drawn with set square, other angle, must be earlier with the ruler limit of drawing, measure the position of another side again with protractor, and draw a little, will put then and the fixed point at angle couples together, bother very much.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of quick angle drawing device simple in structure, easy to use.
The implementation of the utility model purpose is, angle drawing device fast, and two rulers, 2 terminations are connected with rotating shaft 3 with the central point of protractor 1.
Two rulers of the present utility model, 2 terminations are connected with rotating shaft 3 with the central point of protractor 1, when drawing the angle, a ruler are done the one side at angle, measure suitable angle with protractor, with the alignment angle place, limit of another ruler, and with two ruler setting-outs, the required angle of promptly drawing..
The utility model is simple in structure, easy to use, the angle of the various angles of drawing quickly and accurately.
Description of drawings
Accompanying drawing is the utility model structural representation
The specific embodiment
With reference to accompanying drawing, two rulers of the present utility model, 2 terminations are connected with rotating shaft 3 with the central point of protractor 1, when drawing the angle, one ruler is done the one side at angle, measure suitable angle with protractor, the alignment angle place, limit of another ruler, with two ruler setting-outs, the required angle of promptly drawing.
Two rulers 2 have scale, the limit at angle that can accurately draw Len req by scale.
Claims (2)
1. quick angle drawing device is characterized in that two rulers (1) termination is connected with rotating shaft (3) with the central point of protractor (2).
2. quick angle drawing device according to claim 1 is characterized in that two rulers (1) have scale.
