Description

Technical field: [0001] The invention relates to a drawing board, in particular to a drawing board stabilizing device for professional design. Background technique: [0002] Drawing board, that is, a flat plate that is often used to pad drawing paper in sketching and painting. It is often placed on the easel, and some are placed on the knee for drawing. Fix the drawing board on the easel, some use clips, and some use tape. The size of the drawing board depends on the user's requirements. Most of them are made of wood. In addition, there is a kind of plastic drawing board, which can not only draw directly on the board, but also can be wiped off. It is suitable for children's drawing practice, and it is often used in toys. [0003] The current drawing board is less stable when in use, and it is prone to shaking, which affects normal use. Invention content: [0004] It is difficult for the prior art to meet people's needs. In order to solve the above-mentioned problems, the...
