Description
Technical field
The present invention relates to a kind of measurement and drawing instrument, be specially one combination changeable ruler.
Background technology
In daily studying and living, it is often necessary to use various measurement and drawing instrument.The most complete a set of student
Ruler, 45 degree of set squares, 60 degree of set squares and protractor is included with chi.Ruler generally only has the measurement scope of 15cm or 20cm,
And set square, protractor occupy larger space, carry some inconvenience.Ruler, set square and protractor in use, often
Use can be affected owing to being accidentally lost the most a certain part.
Summary of the invention
The purpose of the present invention, is to improve existing ruler, set square, protractor and optimum organization, a kind of group of exploitation
Close changeable ruler.
In order to solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of combination changeable ruler, including ruler first, ruler second, ruler third；Ruler first, ruler second, ruler third length it
Than beingRuler second be respectively arranged at two ends with rotating shaft first, rotating shaft second, one end of ruler first, ruler third passes through rotating shaft respectively
First, rotating shaft second is rotationally connected with ruler second；Ruler first is respectively equipped with location click beetle, locating button second with the other end of ruler third, fixed
Position click beetle, locating button second are box and pin；Ruler first, ruler second, ruler third a side on be carved with length scales first, length respectively
Anale settting scale second, length scales third, another side of ruler first, ruler second is respectively equipped with one section to ruler first, ruler second
Blade side's inflexed protractor circular arc first, protractor circular arc second, protractor circular arc first, protractor circular arc second is 1/4th
Circular arc, arc radius is identical.
Locating button third, locating button fourth is further respectively had on described ruler first, ruler third, locating button third to ruler first one end
Distance is equal to ruler first lengthLocating button fourth is equal to ruler first length to the distance of ruler third one endFixed
Position button third, locating button fourth are box and pin.
Owing to using above-mentioned design, the present invention can produce following change and beneficial effect:
1, long ruler is added.Rotate ruler first, ruler third rotating around rotating shaft first, rotating shaft second, make ruler first, ruler second, ruler
Third is located on a straight line, is made up of the ruler of a lengthening ruler first, ruler second, ruler third.
2,45 degree of set squares and protractor.Location click beetle is fastened with locating button second, by ruler first, ruler second, ruler third
Constitute one 45 degree of set squares, the side of protractor circular arc first, protractor circular arc second Yu ruler second constitute a protractor.
3,60 degree of set squares.Locating button third is fastened with locating button fourth, ruler first, ruler second, ruler third constitutes 1
Degree set square.
4, folding ruler.Ruler first, ruler second, ruler third may be folded on together, and volume after folding diminishes, and is convenient for carrying.
Ruler, set square, the function of protractor are organically combined by the present invention, reached when three is used alone without
The effect that method reaches, carries and uses convenient, and is not easy to lose any of which part.
