[0002] Early childhood education encompasses the cultivation and training of children in moral, intellectual, and physical aspects, covering all aspects of physical and mental development. Its aim is to promote children's all-round development. Some parents require their children to be exposed to painting at an early age in order to improve their cognitive abilities such as observation, imagination, creativity, and problem-solving skills. However, painting requires the use of a drawing board, but some existing drawing boards are too bulky for children to handle. Although some drawing boards are easy to fold, they often have certain shortcomings in practical use, so improvements are needed.

[0003] Chinese patent CN218536191U discloses a foldable portable drawing board, comprising the drawing board and a storage box. The drawing board is foldable, with a central panel connected to two side panels via hinges. The width of the central panel is the sum of the widths of the side panels. Permanent magnets A are positioned at the four corners of the drawing board, engaging with magnetic snaps to secure the drawing paper. When folded, the drawing board can be placed in the storage box. The top cover and sides of the storage box have mounting grooves that mate with the drawing board, allowing it to be placed and secured when unfolded. This invention achieves folding and storage of the drawing board, making it easy to carry. During use, the storage box provides support for the drawing board, making its use more convenient and stable, especially for outdoor sketching.

[0004] However, while the above-mentioned technical solution can achieve the purpose of folding the drawing board for easy use by children, the drawing board gets stuck in the fixing slots A and B after being taken out, making it difficult to adjust the angle. This will cause inconvenience for children when drawing with reference to a certain object due to angle problems or parallax, especially when drawing on the lower part of the drawing board. At this time, the fixed position of the drawing board makes it difficult for children to maintain a comfortable posture for drawing, causing soreness in their hands or body. Therefore, it has certain limitations in use. Utility Model Content
