The card block 120 moves and leaves the card slot 117 under the pulling action of the first connecting rope 121, thereby unlocking the second top support frame 116. The second top support frame 116 automatically pops up and presses against the ground under the action of the first compression spring 115, thereby assisting in supporting the device. The friction block 118 plays a role in increasing friction stability. After loosening the pull ring 125, the card block 120 automatically pops up into the corresponding card slot 117 under the action of the second compression spring 119, thereby re-locking the second top support frame 116. When the drawing pallet 5 is manually rotated to adjust the angle of the drawing pallet 5, the arc frame 3 slides in the arc slide 2, and tightening the fastener 4 can tightly fix the arc frame 3, and the drawing paper can be placed and fixed on the drawing pallet 5 for use.
