The use of straightedges in everyday life and engineering drawing is very common, especially in engineering drawing, various drawing auxiliary tools are various, such as straightedges, set squares, protractors, t-squares, etc., but in the case of auxiliary drawing, these tools are somewhat cumbersome and functionally overlapped with each other, for example: the function of the set square is to draw straight lines at certain angles, such as 90 degrees, 30 degrees, 45 degrees, 60 degrees and the like, the function of the protractor is to measure certain angles, the function of the straight ruler is to draw straight lines, and the function of the T-square is to draw straight lines perpendicular to the frame of the drawing board. These tools often cannot be used alone, but require cooperation with each other, for example: when drawing a straight line which forms an included angle of 90 degrees with the frame of the drawing board, a straight ruler and a protractor are needed, a first straight line of the angle is drawn by the straight ruler, then the protractor is used, an end point of another straight line is pointed according to scales on the protractor, and finally the straight ruler is used for connecting the end point of the first straight line with the end point to obtain another straight line of the angle. Not only is it inconvenient to use, but also the angle drawn may be erroneous because the user needs to determine an end point of another straight line according to the feeling because the scale lines on the protractor are not continuous when the end point is determined.
SUMMERY OF THE UTILITY MODEL
the utility model aims at providing a ruler which can draw angles and equidistant parallel lines at any angle and is extremely convenient to use.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
A ruler convenient for scribing comprises a ruler body, wherein the section of the ruler body is rectangular, length scales are printed on two corresponding edges of the ruler body, at least two circular through holes are formed in the ruler body, annular grooves are formed in the side walls of the circular through holes, 0-360-degree angle scale lines are printed on the peripheries of the circular through holes, an angle measuring frame is arranged at the center of each circular through hole and comprises a first angle measuring frame and a second angle measuring frame, and the central position of the first angle measuring frame is connected with the central position of the second angle measuring frame through a rotating shaft; two ends of the first angle measuring frame are fixedly inserted into the annular groove respectively, two ends of the second angle measuring frame are inserted into the annular groove respectively, and the second angle measuring frame can rotate around the rotating shaft; the first foot measuring frame is printed with first reference scale marks, and the second foot measuring frame is printed with second reference scale marks.
By adopting the technical scheme, the length scales are printed on the two sides of the ruler body, so that a user can conveniently measure the length; the first angle measuring frame and the second angle measuring frame can rotate, and the second angle measuring frame can rotate to form any included angle between the first angle measuring frame and the second angle measuring frame, so that any angle can be drawn only through the ruler; when the angle is drawn, two sides of the angle can be directly drawn according to the first angle measuring frame and the second angle measuring frame, so that the error is reduced; rotate two second angulometry framves to same angle scale mark on, can draw the straight line of two parallels, keep two second angulometry framves unchangeable, remove the ruler for one of them second angulometry frame and a coincidence of the parallel line that has already been drawn, can draw equidistant third parallel line, so on and so on, can draw more equidistant parallel lines.
Further, the cross sections of the first angle measuring frame and the second angle measuring frame are rectangular, the first reference scale mark is arranged along the length direction of the first angle measuring frame, and the second reference scale mark is arranged along the length direction of the second angle measuring frame.
The reference scale marks positioned on the centers of the first angle measuring frame and the second angle measuring frame can facilitate the user to measure the angle.
Further, the first angle measuring frame is fixed on a 0-degree scale of the angle scale mark.
Further inject, four angles of ruler body still paste and are fixed with the protective sheath that is triangle-shaped.
The protective sleeves are pasted at four corners of the ruler, so that abrasion of the ruler can be avoided, and meanwhile, a user can be protected from being scratched carelessly due to the four right angles of the ruler when the ruler is used.
Compared with the prior art, the utility model, angle, equidistance parallel line, the use that can draw arbitrary angle are extremely convenient.
