Wide angle auxiliary drawing tool

Abstract

The invention discloses a wide angle auxiliary drawing tool. The wide angle auxiliary drawing tool comprises a positioning device and a sliding device. The positioning device comprises four positioning bases. The four positioning bases are respectively fixed on four corners of a drawing board, and used for fixing drawing paper. The sliding device comprises four groups of matched sliding rails andsliders. The sliding rails are connected together through the positioning bases. The sliders are installed between the sliding rails and the drawing board, and the sliders are translated along the sliding rails in a horizontal direction or a vertical direction. The interior of each of the sliders is provided with a capacitance grid sensing device, and a sensing layer is correspondingly applied oneach of the sliding rails, and used for measuring a translation distance of the slider on the sliding rail. The upper surfaces of the sliders are provided with an angle indicating device which is usedfor installing a straight ruler and providing the adjustment of any angles. Through moving the straight ruler by the sliders, the wide angle auxiliary drawing tool is capable of realizing horizontaland vertical lines in drawing, providing the selection of multiple angles, and displaying a moving distance, thereby improving the accuracy of the drawing paper and the working efficiency of drawing.

Description

technical field [0001] The invention relates to a drawing tool, in particular to a wide-angle 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, but after tilting at a certain angle, the T-square, which is already difficult to control, becomes more difficult to control, and a slight movement will change it. 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 above problems, the pres...
