Abstract
The invention discloses a multi-functional mathematics plotting tool. The multi-functional mathematics plotting tool comprises a fixed support leg, a movable support leg, a protractor and a compasses tip, wherein the compasses tip is arranged at the bottom end of the fixed support leg; a pencil lead is arranged at the bottom end of the movable support leg; the movable support leg is fixedly connected with the fixed support leg through a rotating shaft; the protractor is fixedly connected with the fixed support leg through a rotating shaft; a telescopic rule is arranged on the surface of the fixed support leg; and the end part of the movable support leg is fixedly connected with a fixing cylinder through a fastening screw. A pair of compasses, a graduated scale, a set square and the protractor are skillfully designed into a whole, and various functions meet standards and serve well.
Description
Technical field
The present invention relates to a kind of educational aid, relate in particular to a kind of multifunctional mathmatical drawing tool.
Background technology
At present, mathematical education, in mathematical studying and Mathematics Application, often to use various mathematic(al) construction instruments, as compasses, rule, set square, protractor, slide calliper rule etc., existing several common mathematical drawing tool is nearly all independent individuality, also have protractor and set square combined, but still function singleness of these mathematic(al) construction instruments, substantially be all to solve more single mapping problem, people are in the time of mathematic(al) construction, just to not complete one or both mappings, but to complete multiple mapping, so inner compasses that are often simultaneously equipped with of people's office bag (school bag), rule, set square, protractor, slide calliper rule etc., due to compasses, rule, set square, protractor, slide calliper rule etc. are all independent individualities, make in people's bag more in disorder, bad management.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of multifunctional mathmatical drawing tool.
The present invention takes following technical scheme to realize: a kind of multifunctional mathmatical drawing tool, and it comprises fixed supporting leg, mobile supporting leg, protractor and compasses point, it is characterized in that: described fixed supporting leg bottom is provided with compasses point; Described mobile supporting leg bottom is provided with pencil-lead; And described mobile supporting leg and fixed supporting leg are connected and fixed by rotating shaft; Between described protractor and fixed supporting leg, be connected and fixed by rotating shaft; Described fixed supporting leg surface is provided with shrinkage-rule; Described mobile leg ends is fixedly connected with stationary magazine creel by trip bolt; Described stationary magazine creel is hollow structure; Described stationary magazine creel rotates freely taking trip bolt as basic point; Described shrinkage-rule comprises the first shrinkage-rule and the second shrinkage-rule; The radius of the first shrinkage-rule in described shrinkage-rule is greater than the radius of the second shrinkage-rule; Described fixed supporting leg and mobile supporting leg material are plank; The surface of described fixed supporting leg and mobile supporting leg has all identified graduation mark.
The present invention has following beneficial effect in sum: compasses, rule, set square, protractor are designed to dexterously one by the present invention, various functional specifications are handy, and have and be convenient to management and the advantage such as easy to carry, and also pen, paper can be put into drawing tool inside, bring great convenience to teacher, student and engineers and technicians, make their working and learning handy.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1, fixed supporting leg; 2, mobile supporting leg; 3, protractor; 4, stationary magazine creel; 5, trip bolt; 6, compasses point; 7, pencil-lead; 8, shrinkage-rule; 9, the first shrinkage-rule; 10, the second shrinkage-rule; 11, rotating shaft.
Detailed description of the invention
As shown in Figure 1, a kind of multifunctional mathmatical drawing tool, it comprises fixed supporting leg 1, mobile supporting leg 2, protractor 3 and compasses point 6, described fixed supporting leg 1 bottom is provided with compasses point 6; Described mobile supporting leg 2 bottoms are provided with pencil-lead 7; And described mobile supporting leg 2 and fixed supporting leg 1 are connected and fixed by rotating shaft 11; Between described protractor 3 and fixed supporting leg 1, be connected and fixed by rotating shaft 11; Described fixed supporting leg 1 surface is provided with shrinkage-rule 8; Described mobile supporting leg 2 ends are fixedly connected with stationary magazine creel 4 by trip bolt 5.
Operation principle of the present invention is, the fixed supporting leg 1 and mobile supporting leg 2 surfaces that adopt plank to make are provided with scale mark, thereby can set it as rule uses, and described fixed supporting leg 1 and mobile supporting leg 2 are connected and fixed by rotating shaft 11, and be connected by rotating shaft 11 between described fixed supporting leg 1 and protractor 3, described protractor 3 can rotate freely, thereby can measure very easily the angle of object; Described fixed supporting leg 1 bottom is provided with compasses point 6; Described mobile supporting leg 2 bottoms are provided with pencil-lead 7, and in the time using, the compasses point 6 that fixed supporting leg 1 bottom is arranged is fixing, make the pencil-lead 7 of mobile supporting leg 2 bottoms settings around its rotation, play the effect of compasses; And described fixed supporting leg 1 surface is provided with shrinkage-rule 8, and described shrinkage-rule 8 comprises the first shrinkage-rule 9 and the second shrinkage-rule 10, can determine in time fixed supporting leg 1 and mobile supporting leg 2 form the size of radius, greatly improved operating efficiency; The stationary magazine creel 4 that described mobile supporting leg 2 surfaces arrange be hollow structure, can deposit other stationery of pencil and some in described stationary magazine creel 4, people is used convenient.
The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
