Problems solved by technology
[0002] When high school students are doing mathematical drawing, they need to use a variety of drawing tools, which makes it more troublesome to carry. In addition, when drawing long straight lines, due to the insufficient length of the measuring stick, multi-section drawing is required, and in the drawing process , it is easy for students to shake the drawing ruler, which affects the normal drawing quality. Therefore, in order to solve such problems, we propose a multi-functional drawing tool for mathematics for high school students

Embodiment
[0020] Embodiment: When in use, students can place the tools for drawing in the storage tank 13 of the drawing board 1, and then carry the device as a whole by moving the wheels 6. Before drawing, first place the support plate 8 from the Take it out from the groove 7 to make it present the most suitable angle for your own drawing. During this process, the slider 9 will slide in the chute 10, and the slider 9 will drive the hinge rod 11 to rotate. After turning to a certain angle, the Insert the insertion rod 17 into a suitable jack 18, fix the angle of the support plate 8, and then spread the paper on the drawing board 1, or use the drawing board 1 to directly draw the drawing. When drawing a long straight line, First twitch the fixed cylinder 4 to make it slide in the fixed groove 5. When the fixed cylinder 4 is separated from the fixed rod 12, turn the drawing ruler 15 to make it rotate to the desired angle and then draw a long straight line. , the spring 14 will always push...

The invention belongs to the field of drawing tools and particularly discloses a multifunctional drawing tool for high school mathematics. The multifunctional drawing tool comprises mounting plates and a drawing plate. The two mounting plates are arranged and symmetrically arranged. Each mounting plate is of a U-shaped structure. The drawing plate is arranged at the top ends of the mounting plates. A cross rod is connected to the top ends of the inner walls of two sides of each mounting plate. The cross rods are in through connection with the drawing plate. The circumferential side wall of each cross rod is sleeved with a drawing ruler. The circumferential side wall of each cross rod is sleeved with a spring. By the adoption of the multifunctional drawing tool, the drawing tool bodies required for high school mathematics drawing can be uniformly stored in a storage tank, and then the device can be pulled to be carried, so that the portability function is realized; moreover, the devicecan effectively prevent drawing paper from shaking during drawing, and the aesthetic degree of drawing can be increased; and moreover, the device can be adjusted at multiple angles during drawing, sothat students can draw conveniently in the drawing posture most suitable for the students, the comfort degree during drawing is increased, and the drawing tool is suitable for popularization.
Description
technical field [0001] The invention relates to the technical field of drawing tools, in particular to a multifunctional drawing tool for high school mathematics. Background technique [0002] When high school students are doing mathematical drawing, they need to use a variety of drawing tools, which makes it more troublesome to carry, and when drawing long straight lines, because the length of the measuring ruler is not enough, it is necessary to draw in multiple segments, and in the drawing process , it is easy for students to shake the drawing ruler, which affects the normal drawing quality. Therefore, in order to solve this kind of problem, we propose a multifunctional drawing tool for mathematics for high school students. Contents of the invention [0003] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, and proposes a kind of multifunctional drawing tool for high school mathematics. [0004] In order to achieve ...
