Problems solved by technology

These existing drawing tools are generally independent single pieces, with many pieces and many sharp corners, which is inconvenient to carry and store. At the same time, the cost is high, the tools are scattered, and it is inconvenient to use, which affects the dimensional accuracy and quality of the drawing.
In addition, traditional drawing boards are made of wood, which may be deformed or moldy when exposed to sunlight or rain or moisture, and may even be damaged by rats, etc.

Embodiment Construction

[0013] Drawing board 1 is made by PVC, makes a guide groove 2 around drawing board respectively, so that main chi 3 is done parallel sliding along guide groove, respectively makes a brace 12 at the two ends of a side of drawing board, uses When it is propped up, the drawing board forms a slope, and the ergonomics principle is used to reduce the fatigue of the drawing person. The main ruler 3 is composed of a ruler head 9 and a ruler body, which are fixed with rivets. A guide rail 7 and a button 8 are set on the ruler head 9. The guide rail on the master ruler can make the ruler move along the guide groove, and the button 8 is used to fix the main ruler. s position. (also guide rail 7 can be set at the end of the ruler simultaneously to ensure synchronous parallel sliding left and right). The ruler body of the main ruler 3 is made of transparent material (such as transparent plastic, plexiglass, etc.), and a chute 4 is opened in the middle of the chi body to facilitate the aux...

The assembled drawing instrument has simple and reasonable structure, easy producing and manufacture,low cost, and convenient use, carrying and keeping.

Description

technical field [0001] The invention relates to a drawing tool for study and work, in particular to a combined plotter integrating a triangular plate, a ruler and a protractor. Background technique [0002] Drawing tools such as drawing boards, T-squares, triangular rulers, and protractors are often used in study and work, especially for engineering students and engineering technicians. These existing drawing tools are generally independent single pieces, with many pieces and many sharp corners, which is inconvenient to carry and store. At the same time, the cost is high, the tools are scattered, and it is inconvenient to use, which affects the dimensional accuracy and quality of drawing. In addition, traditional drawing boards are made of wood, which may be deformed or moldy when exposed to sunlight or rain or damp, and may even be damaged by rats and the like. Contents of the invention [0003] The object of the present invention is to provide a combination plotter that...
