The drawing board axis is located at the upper position of the drawing board.

The support plate shaft is located at the lower position of the support plate.

The size of the gear lever slot opened on the support plate matches the size of the middle gear lever.

When the utility model is in use, the inner bracket is taken out from the outer bracket, the angle between the inner bracket and the outer bracket is adjusted according to the required height, and after the angle is determined, the support plate is rotated around the support plate axis, and the inner bracket is rotated. The upper support rod is placed in the arc-shaped groove on the support plate. At this time, a stable structure is formed between the inner bracket, the outer bracket and the support plate, which can ensure the stability of the drawing board during use, and then rotate the drawing board around the drawing board axis. Take the drawing board out from between the outer brackets until it is rotated until the drawing board is attached to the upper lever. You can place painting tools on the support board for easy access. When not needed, put away the drawing board and make it rotate along the axis of the drawing board. To the outer bracket, to fit the middle gear rod, then turn the support plate to rotate it into the outer bracket, so that the gear rod groove on the support plate is stuck on the middle gear rod, and the inner bracket is retracted into the strip groove of the outer bracket. When the support rod is located in the card slot on the outer bracket, the folded drawing board takes up very little space and is convenient to carry.
