Abstract
Four-in-one learns stationery, the multifunctional learning stationery that exactly the study stationery of four kinds of ruler, set square, compasses and protractor separate components is combined together.That is, a four-in-one study stationery can be transformed into four kinds of ruler, set square, compasses and protractor study stationery respectively.
Description
Technical field
The present invention relates to field of stationery, particularly four-in-one study stationery.
Background technology
Ruler, set square, compasses and the protractor of present student is all to respectively become an object, so to store,
Carry and use is made troubles.
The content of the invention
The task of the present invention is design a kind of four-in-one study stationery in view of the foregoing drawbacks.
The technical proposal for solving the technical problem of the invention is：Ruler, set square, compasses and protractor are melted as one
Body, forms multifunctional learning stationery.
Present invention has the advantages that：Convenient storage, is convenient for carrying, easy to use, multi-purpose content.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples
Fig. 1 is the structure diagram of the embodiment of the present invention
In figure, 1 is protractor, and 2 be the side where protractor bottom, and a right-angle side of set square, while is compasses again
A part for one leg, 3 be another telescopic leg of compasses, i.e. this leg of installation pencil, while be the oblique of set square again
Side, and the length after its elongation is extended equal to another right-angle side 4 of length and set square of the right-angle side 2 where protractor bottom
The sum of length afterwards, 4 be another telescopic right-angle side of set square, while is another part of compasses one leg again, and
Length of its length after extending equal to the right-angle side 2 where protractor bottom.
Protractor 1 is the size of measuring angle.In one end of right-angle side 2 where protractor bottom and compasses install pencil this
One end of bar leg 3 movably connects, the other end of the right-angle side 2 where protractor bottom and another right-angle side 4 of set square
One end movably connects.The other end after pencil this leg 3 contraction is installed in the other end and compasses of another right-angle side 4 of set square
Removable engagement, and the length that the length after pencil this leg 3 is shunk is the right-angle side 2 where protractor bottom is installed in compassesAgain and bevel edge is used as, so that, form isosceles right angle trigonometry with the right-angle side 2 where protractor bottom and another right-angle side 4
Shape, that is, obtain one and containThe set square at angle.The other end and set square after pencil this leg 3 contraction is installed in compasses
The removable engagement of the other end after another contraction of right-angle side 4, installs the length after pencil this leg 3 contraction and is equal to wherein in compasses
Right-angle side 2 where protractor bottom , the length after another right-angle side 4 of set square is shunk is equal to protractor bottom
Right-angle side 2 where portion, then form one with the right-angle side 2 where protractor bottom and contain 30The right angle trigonometry at angle
Contain in shape, that is, set squareThe set square at angle.After another right-angle side 4 of set square is extended and turn to and measure
Right-angle side 2 where the device bottom of angle is into the straight angle, and fixation is not bent, and becomes the one leg of compasses, with installed in compasses pencil this
Bar leg 3 constitutes compasses and (length after pencil this leg 3 elongation is installed in compasses equal to straight where protractor bottom after extending
The sum of length after the length of the arm of angle 2 and another right-angle side 4 elongation of set square).Another right-angle side 4 of set square is stretched
After length and turn to the right-angle side 2 where protractor bottom into the straight angle, and fixation is not bent, installation pencil in compasses this
Leg 3 is overlapped after extending and is fixed on another right-angle side 4 of the right-angle side 2 where protractor bottom and set square, make its into
For the straight line not bent, ruler is so constituted as the right-angle side 2 where protractor bottom and another right-angle side 4 of set square.
After stationery is finished, it is folded up, it is not only easy to use with regard to this, but also convenient storage and carrying, multi-purpose content.
Claims (1)
1. a kind of four-in-one learns stationery, it is characterized in that four kinds ruler, set square, compasses and protractor can be transformed into respectively
Practise stationery.
