The two fixing plates 5 are hinged, and the two fixing plates 5 can rotate. The legs 4 support the fixing plates 5, and the drawing work is carried out through the drawing board body 1. By setting the adjusting component 2, the double-shaft screw rod 22 is rotated in the folding plate 21 by turning the lever 24. The rotation of the double-shaft screw rod 22 drives the two slide plates 23 to move in the folding plate 21. The movement of the slide plate 23 pushes the slider 26 to move in the chute 27 of the fixing plate 5 through the push plate 25. The movement of the slider 26 pushes the two fixing plates 5 to rotate. By setting the adjusting component 2, the drawing board body 1 can be adjusted to different angles for use according to needs, improving the practicability of the device. By setting the placement component 28, when the paintbrush is not in use, the paintbrush can be inserted into the placement groove 282 of the placement base 281. The rubber pad 283 on the inner wall of the placement groove 282 is squeezed, and the paintbrush is not likely to slip out of the placement groove 282. At the same time, the arc-shaped edge 284 is provided at the upper end of the placement groove 282 to facilitate the insertion of the paintbrush into the placement groove 282. By setting the placement component 28, the paintbrush can be stored and placed, avoiding the loss of the paintbrush due to random placement.
