Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description of the principles of the invention is provided in connection with the accompanying drawings.
The utility model provides a portable plane drawing instrument of dismouting, includes four limit frame strips 6, four limit frame strips 6 head and the tail connect perpendicularly for the rectangle frame in order, along the length direction of limit frame strip 6 is equipped with first scale 65 and bevel protractor 61 respectively in the border position of both sides. The angle rule 61 is disposed corresponding to the inner side of the rectangular frame, and the first scale 65 is disposed corresponding to the outer side of the rectangular frame. The angle ruler 61 is calibrated by taking the radius of the center line of the formed rectangular frame as a reference line.
The drawing tool further comprises a first scribing rod 4, a second scribing rod 5 and a third scribing rod 3, wherein two ends of the first scribing rod 4 are respectively in sliding connection with the two oppositely-arranged side frame strips 6 and used for drawing a straight line. The second scribing rod 5 and the first scribing rod 4 are arranged in parallel, two ends of the second scribing rod 5 are connected with the middle point position where two side frame strips 6 are oppositely arranged, one end of the third scribing rod 3 is connected with the middle point of the second scribing rod 5 in a rotating mode, the second scribing rod 5 and the third scribing rod 3 are matched with each other to draw angles and partial arcs, and the numerical value of the angle corresponding to the third scribing rod 3 on the directional angle ruler 61 exactly corresponds to the size of the angle between the third scribing rod 3 and the second scribing rod 5.
Wherein, the scale setting on each marking off pole is as follows:
a second graduated scale 41 which is completely matched with the first graduated scale 65 is carved on the surface of the first marking rod 4;
