[0003] Although the popular drafting tables on the market can be tilted at a certain angle to make the draftsman more comfortable, the T-square, which is already difficult to control, becomes more difficult to control after being tilted at a certain angle, and a slight movement will make it become more comfortable. Crooked, resulting in huge errors, so people often feel that the existing drafting table is not practical

Abstract
The invention discloses a self-adaptive auxiliary drawing tool. The self-adaptive auxiliary drawing tool comprises a positioning device and a sliding device. The positioning device comprises four positioning bases. The four positioning bases are fixed to the four corners of a drawing board correspondingly and used for fixing drawing paper. The sliding device comprises four sets of matched slidingrails and sliding blocks. The sliding rails are connected through the positioning bases. The sliding blocks are mounted between the sliding rails and the drawing board. The sliding blocks translate along the sliding rails in the horizontal direction or in the vertical direction. Three clamping grooves with different angles are formed in each sliding block for fixing a straight ruler. Capacitive grate sensing devices are mounted in the sliding blocks. The sliding rails are correspondingly coated with sensing layers which are used for measuring the translation distances of the sliding blocks onthe sliding rails. The sliding blocks are used for driving the straight ruler, horizontal straight lines and vertical straight lines are drawn during drawing, multiple angles are provided for selection, meanwhile, the movement distances are displayed, and the drawing paper accuracy and drawing operation efficiency are improved.
Description
technical field [0001] The invention relates to a drawing tool, in particular to an adaptive auxiliary drawing tool. Background technique [0002] In the field of art creation and engineering drawing, it is often necessary to use drawing tools to assist drawing. Common drawing tools include T-square, drawing table and so on. [0003] Although the popular drafting tables on the market can be tilted at a certain angle to make the draftsman more comfortable, the T-square, which is already difficult to control, becomes more difficult to control after being tilted at a certain angle, and a slight movement will make it become more comfortable. Crooked, resulting in huge errors, so people often feel that the existing drafting table is not practical. How to make the drawing board not only allow the drafter to tilt the angle comfortably, but also draw freely and accurately has become a problem that needs to be solved urgently. Contents of the invention [0004] In view of the abo...
