Description

Multifunctional drawing rule

Technical Field

The utility model relates to a drawing tool, specifically speaking relate to a multi-functional drawing rule.

Background

Nowadays, all domestic industrial and scientific professions set up a professional basic course for engineering drawing, and the course requires students to master basic manual drawing skills, and many students find that the spatial sense and the imagination of the students reach the standards when drawing, but have obvious differences when the students are put into practice on the pen head. In addition, in some industrial courses, some curves need to be drawn, and readings need to be found from the curves, and many students often cannot obtain accurate conclusions due to insufficient drawing precision.

First, the existing drawing rule for drawing a drawing by hand, such as a t-square, is difficult to maintain horizontally due to the manufacturing errors of the drawing board and the rule itself when in use, resulting in that a large-span straight line is difficult to draw directly. In addition, the ruler can rub with the existing works in the moving process, so that the drawing is blurred, and the aesthetic property of the whole large drawing is obviously affected.

Secondly, the pencil tip has a certain width, so that the drawing accuracy cannot be maintained in the drawing process, the accuracy of a series of subsequent operations of the drawing is further influenced, and a large error is finally obtained due to the accumulative effect of the error.
