[0002] In mathematics major learning, accurate drawing is very important for understanding and mastering mathematical concepts. However, under the existing technical conditions, students often face many problems when drawing.

[0003] In terms of fixing drawing paper, traditional drawing tools often cannot effectively fix drawing paper, and drawing paper is prone to sliding or wrinkling during drawing, which greatly affects the quality and accuracy of drawing. Students may use temporary fixing methods such as adhesive tape, but these methods are not only inconvenient to operate, but also may damage the drawing paper or leave marks on the paper.

[0004] In terms of angle adjustment, existing drawing tools usually do not have convenient angle adjustment function, or the adjustment process is complex and unstable. This makes it difficult for students to obtain the best drawing angle when drawing three-dimensional figures and other situations requiring different viewing angles, thereby affecting the accuracy and efficiency of drawing.

[0005] To solve these problems, the technical scheme provides a drawing auxiliary tool for mathematics major learning. SUMMARY

[0006] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology, and to provide a drawing auxiliary tool for mathematics major learning.

[0007] To solve the above technical problems, the technical scheme provided by the utility model is a drawing auxiliary tool for mathematics major learning: including a bottom support plate, the projection of the bottom support plate in the overhead direction is a rectangle;

[0008] Two side support plate bodies are symmetrically arranged on both sides of the bottom support plate, and a functional long hole body is arranged on the side support plate body;

[0009] It also includes a core pressing long block, the number of core pressing long blocks is two, the lower side of the core pressing long block is provided with a pressing long plate body, the two sides of the core pressing long block are symmetrically provided with a side shaft body, the side shaft body extends into the functional long hole body, and the outer side of the core pressing long block and the inner side of the side support plate body are in sliding fit; the pressing long plate body is closer to the bottom support plate than the core pressing long block.

[0010] As an improvement, the middle core long slot hole of the functional long slot hole body extends from one end of the side support plate body to the other end of the side support plate body; the extension direction of the core long slot hole and the plane where the bottom support plate is located are parallel to each other, the side guide hole of the functional long slot hole body continues to extend to the side of the functional long slot hole body, and the side core hole of the functional long slot hole body is located at the outermost side of the functional long slot hole body; the side guide hole and the core long slot hole are connected and communicated, and the side guide hole and the side core hole are connected and communicated; the distance between the side guide hole and the bottom support plate decreases linearly from the connection between the side guide hole and the core long slot hole to the connection between the side guide hole and the side core hole.

[0011] As an improvement, rubber support blocks are fixedly arranged on the lower rear sides of the bottom support plate.

[0012] As an improvement, an arc-shaped shell is fixedly arranged at the front side edge of the bottom support plate, a core pipe body is fixedly arranged on the lower side of the outer side of the arc-shaped shell, the core pipe body extends downward and forward, a nut is fixedly arranged at the lower opening of the core pipe body, a bolt is arranged on the nut, the bolt and the nut are threadedly connected, the shank portion of the bolt extends to the inner side of the core pipe body, and a rubber support pad body is fixedly arranged on the head of the bolt.

[0013] Compared with the prior art, the drawing paper is fixed firmly.

[0014] With the aid of the two core pressing long blocks, the pressing long plate body and the side support plate body on the lower side thereof, and the design of the functional long slot hole body including the core long slot hole, the side guide hole and the side core hole, the drawing paper can be effectively fixed. When the side shaft bodies on both sides of the core pressing long blocks are moved between different hole positions, the pressing long plate body can not only smooth the drawing paper, but also firmly press and fix the drawing paper in the final position. This ensures that the drawing paper will not slide or wrinkle during drawing, and ensures the quality and accuracy of drawing.

[0015] Angle adjustability:

[0016] The drawing aid realizes easy adjustment of the angle of the bottom support plate 1 through the cooperation of the core pipe body 12, the nut 13 and the bolt 14 on the lower side of the arc-shaped shell 11 at the front side edge of the bottom support plate 1. This provides great convenience for different drawing needs in mathematics professional learning, such as drawing different perspectives of three-dimensional figures. Students can flexibly adjust the angle of the bottom support plate according to their actual needs to obtain the best drawing perspective, thereby improving the accuracy and efficiency of drawing.

[0017] High stability:

[0018] The rubber support blocks 10 are fixed on the lower side rear part of the bottom support plate 1, and work together with the rubber support pads 15 of the head part of the bolt 14 to provide stable support for the drawing aid. The rubber material can increase the friction with the desktop, prevent the drawing aid from sliding during use, and reduce the impact on drawing caused by uneven desktop and other factors. This stable support structure allows students to focus and be at ease when drawing, without worrying about the shaking of the drawing aid affecting the drawing effect. BRIEF DESCRIPTION OF DRAWINGS

[0032] Further comprising core pressing long blocks 7, the number of the core pressing long blocks 7 is two, the lower side of the core pressing long block 7 is provided with a pressing long plate body 8, and the two sides of the core pressing long block 7 are symmetrically provided with side shaft bodies 9, the side shaft bodies 9 extend into the functional long hole body 3, and the outer side of the core pressing long block 7 and the inner side of the side support plate body 2 are slidingly fitted; the pressing long plate body 8 is closer to the bottom support plate 1 than the core pressing long block 7.

[0033] The lower side of the bottom support plate 1 is fixedly provided with rubber support blocks 10 at the rear sides.

[0034] The bottom support plate 1 is fixedly provided with an arc-shaped shell 11 at the front side edge, the outer side of the arc-shaped shell 11 is fixedly provided with a core pipe body 12 at the lower side, the core pipe body 12 extends downward and forward, the lower side opening of the core pipe body 12 is fixedly provided with a nut 13, the nut 13 is provided with a bolt 14, the bolt 14 and the nut 13 are threadedly matched, the stud portion of the bolt 14 extends to the inner side of the core pipe body 12, and the head of the bolt 14 is fixedly provided with a rubber support pad body 15.

[0045] With the help of the two core pressing long blocks 7, and the pressing long plate body 8 on the lower side and the functional long hole body 3 on the side support plate body 2, including the core long hole 4, the side guide hole 5 and the side core hole 6, the drawing paper can be effectively fixed. When the side shaft bodies 9 on both sides of the core pressing long blocks 7 move between different hole positions, the pressing long plate body 8 can both smooth the drawing paper and firmly press and fix the drawing paper in the final position. This ensures that the drawing paper does not slip or wrinkle during drawing, ensuring the quality and accuracy of the drawing.

[0046] Angle adjustability:

[0047] The drawing aid realizes easy adjustment of the angle of the bottom support plate 1 through the cooperation of the core pipe body 12, the nut 13 and the bolt 14 at the lower side of the arc-shaped shell 11 at the front side edge of the bottom support plate 1. This provides great convenience for different drawing needs in mathematics professional learning, such as drawing different perspectives of three-dimensional figures. Students can flexibly adjust the angle of the bottom support plate according to their actual needs to obtain the best drawing perspective, thereby improving the accuracy and efficiency of drawing.

[0048] High stability:

[0049] The rubber support blocks 10 are fixed at the lower side of the rear part of the bottom support plate 1, and jointly act with the rubber support pad bodies 15 of the heads of the bolts 14 to provide stable support for the drawing aid. The rubber material can increase the friction with the desktop to prevent the drawing aid from sliding during use and reduce the impact on drawing caused by uneven desktop and other factors. This stable support structure enables students to focus more on drawing and be more at ease, without worrying about the shaking of the drawing aid affecting the drawing effect.

[0050] Simple operation:

[0051] Whether it is adjusting the angle of the bottom support plate or fixing the drawing paper, the operation is very simple and intuitive. For students, there is no need for complex operation steps to quickly get started using the drawing aid. For example, adjusting the angle only needs to rotate the bolt 14, and fixing the drawing paper only needs to push the core pressing long block 7. This simple operation method saves time and improves learning efficiency.

[0052] The above describes the present application and its embodiments, which are not restrictive. The embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired by this, without departing from the creative purpose of the present application, without creative design, similar structure and embodiments of the technical solution can be designed, which should belong to the protection scope of the present application.
