When adjusting, first pull down the latch 802 to drive the triangular clamping block 804 to move out of the triangular clamping groove 806. At this time, the second spring 803 is compressed. Then, the drawing paper support plate 6 is rotated to adjust the inclination angle of the drawing paper support plate 6. After adjustment, release the latch 802, and the elastic force of the second spring 803 drives the triangular clamping block 804 to be inserted into the triangular clamping groove 806, so that the turntable 805, the support shaft 601 and the drawing paper support plate 6 are fixed.

[0036] Working principle: When the auxiliary device for art practice is used, the threaded sleeve 401 is rotated by twisting the rotating rod 402, and the threaded sleeve 401 is rotated to drive the threaded rod 403 to move up and down, and the threaded rod 403 drives the drawing paper support plate 6 to move up and down, thereby adjusting the height of the drawing paper support plate 6; the triangular clamping block 804 is moved out of the triangular clamping groove 806 by pulling down the latch 802, at which time the second spring 803 is compressed, and then the drawing paper support plate 6 is rotated to adjust the inclination angle of the drawing paper support plate 6. After adjustment, the latch 802 is released, and the elastic force of the second spring 803 is used. Drive the triangular card block 804 to be inserted into the triangular card slot 806, so that the turntable 805, the support shaft 601 and the drawing paper support plate 6 are fixed; after the height and angle of the drawing paper support plate 6 are adjusted, the push-pull plate 703, the guide rod 705 and the clamping plate 707 are pulled upward through the handle 704, so that the clamping plate 707 is separated from the drawing paper support plate 6, and then the paper is placed on the drawing paper support plate 6, and then the handle 704 is forced in the left and right directions, and the sliding sleeve 701, the connecting frame 702, the push-pull plate 703, the guide rod 705, the first spring 706 and the clamping plate 707 are driven by the handle 704. The paper is pressed onto the drawing paper support plate 6 by moving the pressing plate 707 left and right. When the pressing plate 707 is in the right position, the handle 704 is released. The pressing plate 707 is pressed onto the drawing paper support plate 6 by the elastic force of the first spring 706. Similarly, the other end of the paper is pressed onto the drawing paper support plate 6 by another paper pressing mechanism 7. Then, the person uses the color palette 501 to mix colors, and then uses the paintbrush 502 to dip the paint in the color palette 501 to paint on the paper. After the painting is finished, the top cover 11 is opened, clean water is added into the cleaning box 10, and then the color palette 501 is placed inside the cleaning box 10. The bottom end is inserted into the through hole 1207, and the brush 502 is pressed into the through hole 1207 by tightening the clamping bolt 1208. Then, the top cover 11 is closed, and the electric motor 1201 is started to drive the first gear 1202, the second gear 1203, and the driving shaft 1204 to rotate. The brush plate 1205 and the extension block 1206 are driven to rotate through the driving shaft 1204. The palette 501 is cleaned by the rotation of the brush plate 1205, and the rotation of the extension block 1206 drives the brush 502 to rotate. When the brush 502 rotates, it impacts with the water flow, thereby washing away the paint on the brush 502.
