Problems solved by technology

[0002]At present, the commonly used manual drawing tools include ruler, set square, T-square, square, protractor, compass, horizontal angle ruler, etc., because the structures of each drawing tool are different, Moreover, its function is relatively single. When doing manual drawing, multiple drawing tools need to cooperate with each other to complete the drawing task. Especially when drawing complex graphics, each drawing tool needs to cooperate with each other and use them alternately. Many auxiliary steps leave a lot of drawing marks on the drawing, which is cumbersome to operate, and the drawing marks are easy to be confused, which leads to drawing errors and needs to be re-modified, resulting in unclean drawing, affecting the efficiency of drawing, and the cleanliness of the drawing , and too many marks on the drawing surface will also affect the accuracy of the drawing, leading to an increase in the drawing error and seriously affecting the quality of the drawing. In addition, when drawing, the drawing personnel should use one hand to hold down the drawing tools such as the T-square, the set square, and the other A hand holding a pencil to draw a line, scrambling
When drawing, you need to carry multiple drawing tools. The drawing tools are wide and narrow, different in length, and uneven. It is very inconvenient to carry. A large number of drawing tools may be lost or missed.

Abstract

The invention relates to a combined drawing device with ruler, gauge and drawing board, which comprises a T-square, which is set on the drawing board and moves up and down along both sides of the drawing board. The middle part of the T-square is provided with a horizontal chute for measuring angles. The connecting plate moves along the horizontal chute, the upper end of the measuring angle connecting plate is a protractor, the square and the protractor are connected through the measuring angle shaft, one side of the square is provided with a vertical chute, one end of the brace moves along the vertical chute, and the other end of the brace moves The marking needle is set and connected with one end of the rotary ruler, the other end of the rotary ruler is provided with a pencil, and the rotary ruler, the marking needle and the pencil form a compasses. The invention combines drawing tools such as a drawing board, a T-square, a square, a protractor, and compasses, and can draw horizontal lines, vertical lines, straight lines at different angles, and circles. Effectively improve drawing efficiency, ensure drawing quality, and effectively reduce the possibility of omission and loss.

Description

Technical field: [0001] The invention relates to a drawing tool, in particular to a ruler-compass drawing-board combined drawing device which combines drawing tools such as a drawing board, a T-square, a protractor, and a compass. Background technique: [0002] At present, the commonly used manual drawing tools include ruler, set square, T-square, square, protractor, compasses, horizontal angle ruler, etc., because the structures of each drawing tool are different, and their functions are relatively single, multiple drawings are required for manual drawing Only when the tools cooperate with each other can the drawing task be completed, especially when drawing complex graphics, each drawing tool needs to cooperate with each other and use them alternately. During the drawing process, many auxiliary steps need to be done, and many drawing marks are left on the drawing. , the operation is cumbersome, and the drawing marks are easy to be confused, which leads to drawing errors ...
