[0002] In the process of learning to draw, such as sketching and watercolor, it is necessary to fix the drawing paper on the drawing board or easel to improve the stability of the drawing paper and prevent it from shifting due to friction between the hand, pen tip and the paper during the drawing process, which would affect the drawing process.

[0003] In the traditional painting process, the painting paper is usually pasted onto the surface of the painting board using double-sided tape or other adhesive tape. After the painting is finished, the paper needs to be separated from the double-sided tape or other adhesive tape when removing the painting. However, because traditional double-sided tape and other adhesive tape have a certain degree of stickiness and a large adhesive area on the painting paper, improper handling during the removal process can easily cause damage to the painting paper or leave too much residue on the painting paper that is difficult to clean, affecting the aesthetics of the painting. Utility Model Content
