Abstract

The invention relates to a straight line drawing assistor. The straight line drawing assistor comprises a pen cap, a limiting screw, a first connecting frame, a second connecting frame, a first rollerand a second roller, wherein the first connecting frame and the second connecting frame are respectively arranged on two opposite sides of the pen cap; the first roller is fixed at one end of the first connecting frame, and the other end is movably connected with the pen cap; the second roller is fixed at one end of the second connecting frame, and the other end of the second connecting frame ismovably connected with the pen cap; a placing hole is formed in the center of the pen cap; and the limiting screw is arranged on the side face, adjacent to the side face where the first connecting frame and the second connecting frame are located, of the pen cap. Compared with the prior art, the straight line drawing assistor has the advantages of being simple in operation, convenient to carry andcapable of improving straight line drawing stability.

Description

technical field [0001] The invention relates to the technical field of geometric and mathematical drawing, in particular to an auxiliary device for drawing straight lines. Background technique [0002] Drawing plays an essential role in the early stage of design, and the continuous update of drawing tools and products will inevitably enable designers to expand their thinking in the design stage, showing renderings with a stronger sense of picture and more accurate proportions. This high-efficiency change is created by the unique advantages of drawing tools. Exploring and researching the role of drawing tools in the drawing process and the future development direction of drawing tools has the progressive significance of advocating hand-drawing and improving drawing efficiency. People have the need to draw straight lines in many situations. However, rulers have the limitations of being difficult to draw multiple parallel lines, easy to get dirty and difficult to clean, and una...
