Problems solved by technology
As we all know, a drawing pencil can only draw one line diameter. In the actual drawing work, pencils of various line diameters are used for drawing, and the pencils need to be replaced frequently, which affects the work efficiency of drawing, and many pencils are not easy to carry. Convenience; in addition, there is currently a drawing device that can change the thickness, which is controlled by the pressure between the pen tip and the drawing, and the force should be controlled at all times during use, which is very inconvenient to use

The invention relates to a multifunctional drawing pencil, which mainly comprises a pencil sleeve (1), inner penholders (2), pencil cores (3), a main penholder (4) and a pencil cap (5). The multifunctional drawing pencil can switch the inner penholders (2) at any time based on different needs to switch pencil cores with different wire diameters in a short time so as to overcome the disadvantage that one drawing pencil can only draw one wire diameter and pencils should be changed frequently for actual use, improve drawing efficiency and achieve the purpose of multiuse.
Description
A multipurpose drawing pencil Technical field The invention relates to a drawing pencil, in particular to a multipurpose drawing pencil. Background technique As we all know, a drawing pencil can only draw one line diameter. In the actual drawing work, pencils of various line diameters are used for drawing, and the pencils need to be replaced frequently, which affects the work efficiency of drawing, and it is not easy to carry a lot of pencils. Convenient; in addition, there is currently a drawing device that can change the thickness, which is controlled by the pressure between the tip of the pen and the drawing, and the force must be controlled at all times during use, which is very inconvenient to use. Contents of the invention The purpose of the present invention is to overcome the above disadvantages and provide a multi-purpose drawing pencil to achieve the purposes of multi-purpose, convenient drawing, improved work efficiency, and easy to carry. To achieve the ab...
