In figure：1- rectangle ruler bodies；The left grooves of 2-；The right grooves of 3-；4-；5- straight lines.
Embodiment
The technical solution of the utility model is described in further detail below in conjunction with Figure of description.
As shown in Figs. 1-3, a kind of ruler for drawing angle, including transparent rectangle ruler body 1,1 one length of rectangle ruler body
While for the first scale while, the first scale side is equipped with equi-distance scale line, rectangle ruler body 1 be equipped with two shift to install to wearing length
Groove, two are respectively left groove 2 and right groove 3 to wearing elongated slot, and left groove 2 and right groove 3 are correspondingly arranged at 1 left part of rectangle ruler body and right part and put down
Row is in the first scale side, and another long side of rectangle ruler body 1 is the second scale side, and the second scale side, which is equipped with, to be used to draw the non-of angle
Equidistant angle index mark.
In order to realize the drafting respectively of low-angle and wide-angle, the right end of left groove 2 and the left end of right groove 3 are arc-shaped edges,
The left 2 right end center of circle of groove is vertical with rectangle ruler 1 long side of body with the line direction in the right 3 left end center of circle of groove, the left scale of groove 2 to the first side
Distance is more than the distance on the right scale of groove 3 to the first side, and the angle index mark on the second scale side of the left lower section of groove 2 is from left to right pressed
Arrange from small to large；The angle index mark on the second scale side of the lower section of right groove 3 from left to right by arranging from big to small.Pass through handle
Left groove 2 is arranged at the lower section of right groove 3, realizes that the smaller angle of left groove 2 is drawn, realizes the drafting of the larger angle of right groove 3.
Integer angle in order to realize 4 ~ 90 degree is drawn, and the angle index of left groove 2 is identified since 4 degree of left end by 1 degree
Untill difference is incremented to 10 degree；Untill the angle index mark of right groove 3 is decremented to 10 degree since 90 degree of left end by 10 degree, two
Identified between 10 degree of adjacent scales equipped with 5 degree of angle index.Left groove 2 realizes 4 degree of integer low-angles started to 10 degree
Draw, right groove 3 realizes being drawn with 5 degree of wide-angles for progressive quantity from 10 degree to 90 degree, and left and right groove combination can be realized
Integer angle from 4 degree to 90 degree is drawn.
For more convenient drafting angle line, the lower end of angle index mark and the second scale side vertical connection, angle
Scale marker is identified equipped with corresponding angular values.With the second scale side alignment angles scale marker end easy to angle line
Baseline alignment during drafting, angular values identify the scale that the personnel of drawing can be helped more quickly to distinguish different angle.
For the ease of distinguishing 5 degree of lines and 10 degree of lines, angle index is identified as line segment, 5 degree of angle index of the right lower section of groove 3
Mark line segment is shorter in length than 10 degree of angle index mark line segments.It is longer than the setting of 5 degree of middle separated times by 10 degree of lines, easy to distinguish
5 degree of lines and 10 degree of lines.
Below for draw 7 degree low-angle and 20 degree of wide-angle exemplified by：
When drawing 7 ° of angles, the true edge that one section of straight line 5 makees 7 ° of angles is drawn on paper, left 2 right end of groove is aligned straight on paper
The right end of line 5, and make the cusp of pen 4 in the right end of straight line 5.Using left 2 right end of groove as the center of circle, rectangle ruler body 1 is rotated clockwise, directly
Straight line 5 is touched to lower left scale " 7 ", holds a pen 4 along left 2 right-to-left setting-out of groove, the another a line for completing 7 ° of angles has been drawn
Into.
When drawing 20 ° of degree angles, one section of straight line 5 is drawn first on paper, this is a line at 20 ° of angles, and right 3 left end of groove is aligned
The left end of straight line 5 on paper, and make nib point in the left end of straight line 5.Using right 3 left end of groove as the center of circle, rectangle ruler body is rotated counterclockwise
1, until lower right scale " 20 " touches straight line 5, hold a pen along the right setting-out from left to right of groove 3, complete the another a line at 20 ° of angles.
So far, 20 ° of angles are completed.
A kind of ruler for drawing angle shown in figure 1 above -3 is specific embodiment of the utility model, has been embodied
Go out the utility model in essence feature and progress, can according to actual use needs, under the enlightenment of the utility model, to its into
The equivalent modifications of row shape, structure etc., this programme protection domain row.
