Abstract
This utility model discloses a multifunctional drawing rule for mathematics, composed of a scale (1), a rotating shaft (2), and a movable ruler (3), wherein the scale (1) is in fixed connection with the left end of the movable ruler (3) through the rotating shaft (2), which is characterized in that a guide pin (4) is provided at the right end of the scale (1), a pencil clamping head (5) is provided at the right end of the movable ruler (3), an arc positioning ruler (6) is fixed on the right part of the scale (1), the right end of the movable ruler (3) slides on the arc positioning ruler (6), and scale lines (9) are provided on the scale (1), the movable ruler (3) and the arc positioning ruler (6). The multifunctional drawing rule for mathematics has simple structure, easy operation, easy use, capability of plotting various graphics, improved plotting efficiency and quality, and carry and manage convenience.
Description
Technical field
The utility model relates to a kind of improvement of mathematics drawing instrument, a kind of specifically multifunctional mathmatical drawing rule.
Background technology
In the teaching and study of mathematics, the capital runs into the drafting of mathematic graph, such as, draw straight line, line segment with ruler, draw the angle with angle board, use the compasses draw circles, in order to draw various figures, various drawing instruments all will carry in Faculty and Students, cause instrument more and chaotic, be not easy management, carry difficulty, reduced efficiency of teaching.
Summary of the invention
The purpose of this utility model is to provide a kind of operation simple in structure, easy to use, easy, can draw the multifunctional mathmatical drawing rule of multiple figure.
In order to reach above purpose, the technical scheme that the utility model adopted is: this multifunctional mathmatical drawing rule, constitute by scale, rotating shaft and moving chi, the left end of scale and moving chi is connected and fixed by rotating shaft, it is characterized in that: the right-hand member at scale is provided with pilot pin, right-hand member at moving chi is provided with the pencil chuck, pencil is installed on the pencil chuck, arc positioning rule on the right part of scale is fixing, the right-hand member of moving chi slides on the arc positioning rule, all is provided with graduation mark on scale, moving chi and arc positioning rule.
The utility model is also implemented by following measure: described arc positioning rule is a hollow sleeve, is provided with the arc shrinkage-rule in its tube chamber, is provided with graduation mark on the arc shrinkage-rule, the fixing upper stop piece in the outer end of arc shrinkage-rule.
The beneficial effects of the utility model are: the utility model operation simple in structure, easy to use, easy, can draw multiple figure, and improved drawing efficiency and quality, and be convenient for carrying and manage.
Description of drawings
Fig. 1 is a structure schematic top plan view of the present utility model.
The specific embodiment
Make the utility model with reference to accompanying drawing 1.This multifunctional mathmatical drawing rule, by scale 1, rotating shaft 2 and moving chi 3 constitute, the left end of scale 1 and moving chi 3 is fixing by rotating shaft 2, chi 3 can be rotated around rotating shaft 2 on scale 1, it is characterized in that: the right-hand member at scale 1 is provided with pilot pin 4, right-hand member at moving chi 3 is provided with pencil chuck 5, pencil is installed on the pencil chuck 5, can pilot pin 4 draw circle like this for the center of circle, arc positioning rule 6 on the right part of scale 1 is fixing, the right-hand member of moving chi 3 slides on arc positioning rule 6, at scale 1, all be provided with graduation mark 9 on moving chi 3 and the arc positioning rule 6, can draw angle and triangle according to the angle on the arc positioning rule 6, can draw straight line and line segment by scale 1.
Described arc positioning rule 6 is a hollow sleeve, be provided with arc shrinkage-rule 7 in its tube chamber, on arc shrinkage-rule 7, be provided with graduation mark, the fixing upper stop piece 8 in the outer end of arc shrinkage-rule 7, when moving chi 3 open angles hour, use the scale on the arc positioning rule 6 to measure, when moving chi 3 open angles were big, when the length of arc positioning rule 6 was not enough, moving chi 3 can promote catch 8, arc shrinkage-rule 7 is extracted out, to draw bigger angle or circle in arc positioning rule 6.
Claims (2)
1. multifunctional mathmatical drawing rule, constitute by scale (1), rotating shaft (2) and moving chi (3), the left end of scale (1) and moving chi (3) is connected and fixed by rotating shaft (2), it is characterized in that: the right-hand member at scale (1) is provided with pilot pin (4), right-hand member at moving chi (3) is provided with pencil chuck (5), in the fixing arc positioning rule (6) that goes up of the right part of scale (1), the right-hand member of moving chi (3) is gone up in arc positioning rule (6) and is slided, and all is provided with graduation mark (9) on scale (1), moving chi (3) and arc positioning rule (6).
