At this time, the two movable frames 10 will be attracted by the action of the second magnet 13, so that the two movable frames 10 support the bottom of the second tabletop 11 and ensure that the second tabletop 11 will not slide down, thus completing the horizontal tabletop design. When vertical painting is required, reverse the operation to turn the horizontal tabletop into a vertical tabletop. The operation is simple and convenient, improving the practicality of the easel.

[0031] When used by people of different heights, turning the handle 25 drives the worm gear 24 to rotate, which in turn drives the worm wheel 22 to rotate, thereby driving the threaded rod 14 to rotate. This causes the moving block 15 to move, and then the connecting plate 16 drives the horizontal plate 17 to move accordingly. This, in turn, drives the two first supports 18 to move through the two sliding columns 19, and then drives the second support 21 to move through the fixing plate 20. This allows the two first supports 18 to slide inside the two second frames 2, and the second support 21 to slide inside the third frame 3, thereby adjusting the height of the easel to suit the painting requirements of different heights and improving the versatility of the easel.
