Description
Technical field
The utility model relates to a kind of educational aid, particularly relates to a kind of multifunctional mathmatical drawing tool.
Background technology
At present, mathematical education, various mathematic(al) construction instrument often will be used in mathematical studying and Mathematics Application, as compasses, rule, set square, protractor, slide calliper rule etc., existing several common mathematical drawing tool is nearly all independent individuality, also have and protractor and set square combined, but these mathematic(al) construction instruments still function singleness, substantially be all to solve more single mapping problem, people are when mathematic(al) construction, just to not complete one or both mappings, but multiple mapping will be completed, so the office bag (school bag) of people is inner often compasses are housed simultaneously, 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 the bag of people more in disorder, bad management.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of multifunctional mathmatical drawing tool.
The utility model is taked 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; Be connected and fixed by rotating shaft between described protractor and fixed supporting leg; 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 is that basic point rotates freely with trip bolt; 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 utility model has following beneficial effect in sum: compasses, rule, set square, protractor are designed to one by the utility model dexterously, various functional specification is 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.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
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, and described fixed supporting leg 1 bottom is provided with compasses point 6; Described mobile supporting leg 2 bottom is provided with pencil-lead 7; And described mobile supporting leg 2 and fixed supporting leg 1 are connected and fixed by rotating shaft 11; Be connected and fixed by rotating shaft 11 between described protractor 3 and fixed supporting leg 1; Described fixed supporting leg 1 surface is provided with shrinkage-rule 8; Described mobile supporting leg 2 end is fixedly connected with stationary magazine creel 4 by trip bolt 5.
Operation principle of the present utility model is, the fixed supporting leg 1 adopting plank to make and mobile supporting leg 2 surface are provided with scale mark, thus rule can be it can be used as to use, and described fixed supporting leg 1 and mobile supporting leg 2 are connected and fixed by rotating shaft 11, and described fixed supporting leg 1 is connected by rotating shaft 11 with between protractor 3, described protractor 3 can rotate freely, thus can measure the angle of object very easily; Compasses point 6 is provided with bottom described fixed supporting leg 1; Be provided with pencil-lead 7 bottom described mobile supporting leg 2, when deployed, the compasses point 6 arranged bottom fixed supporting leg 1 fixed, the pencil-lead 7 arranged is rotated around it, play the effect of compasses bottom mobile supporting leg 2; 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, substantially increase operating efficiency; The stationary magazine creel 4 that described mobile supporting leg 2 surface is arranged be hollow structure, can deposit pencil and some other stationery, people are used convenient in described stationary magazine creel 4.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
