Abstract
A kind of protractor with ruler, is hollow protractor, it is characterized in that：A ruler is set on the straight flange of hollow protractor, one end of ruler is flexibly connected with straight flange centrally through rotating shaft.Simple structure of the present invention, it is easy to use, both can accurately measure the size of angle, moreover it is possible to the convenient planar graph for drawing angle and specified angle.
Description
Technical field
The present invention relates to study article, particularly a kind of protractor with ruler.
Background technology
Common function of angle gauge is single, can only be used for measuring angle, or draw some simple straight bases and camber line.
Often measure inaccurate because of the error of eyes when angle is measured；Needing to draw angle and specifying
When angle draws triangle or polygon, common protractor and ruler is nor very applicable.Therefore, having must
It is further improved.
The content of the invention
Angle is can accurately measure it is an object of the invention to provide one kind, and the amount with ruler of angle drafting can be facilitated
Angle device.
The protractor with ruler, is a hollow protractor, it is characterized in that：In the straight flange of hollow angulation heat
On set a ruler, one end of ruler is flexibly connected with straight flange centrally through rotating shaft.
Simple structure of the present invention, it is easy to use, both can accurately measure the size of angle, moreover it is possible to conveniently paint
Angle processed and the planar graph of specified angle.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples
Fig. 1 is structural representation of the invention.
In figure：1st, hollow protractor, 2, ruler
Specific embodiment
By the following examples, the present invention is described in more detail, but as long as in idea of the invention
In the range of, it is not limited in following examples.
In Fig. 1, the protractor with ruler is hollow protractor, it is characterized in that：In hollow protractor 1
Straight flange be provided with ruler 2, one end of ruler 2 is flexibly connected with straight flange centrally through rotating shaft.Ruler 2
Both sides are designed with scale, can be rotated around rotating shaft, and when angle is measured, ruler 2 can refer to as one
Pin, accurately points out the value of angle.Because protractor is hollow, the number of degrees that can be indicated according to ruler 2 draw
Corresponding angle, can be used to draw the angle of the specified number of degrees and other contain angled planar graph.Ruler 2 can revolve
The lower section of protractor is gone to, angle is drawn or when common ruler is used.
Above-described embodiment is only one of presently preferred embodiments of the present invention, not limits protection model of the invention with this
Enclose, therefore：The equivalence changes that all shapes under this invention, structure, principle are made, all should be covered by the present invention
Protection domain within.
Claims (1)
1. a kind of protractor with ruler, is hollow protractor, it is characterized in that：In the straight of hollow protractor 1
A ruler 2 is set on side, one end of ruler 2 is flexibly connected with straight flange centrally through rotating shaft.
