[0037] Working principle: When children need to copy paintings, parents can first transmit the pictures that children want to copy to the inside of the projection device 9 through the network. Parents open the first electric slide 5 and the second electric slide 6, adjust the position of the projection device 9 through the moving parts on the surfaces of the first electric slide 5 and the second electric slide 6, and turn on the driving motor 72, so that the movable frame 8 drives the projection device 9 to rotate, and the projection head of the projection device 9 is irradiated on the transparent drawing board 2. At this time, the parent turns on the second motor 201, and the second motor 201 drives the finger cylinders 22 on both sides above to move backward, so that the finger cylinders 22 move to the drawing paper, and the finger cylinders 22 close and pull the drawing paper forward. The drawing paper is spread on the transparent drawing board 2. At this time, the pattern projected by the projection device 9 is on The drawing paper appears, the second cylinders 172 on both sides are opened, and one side of the drawing paper is pressed by the pressing piece 174, and then the third electric slide 18 and the third cylinder 191 are opened, and the moving parts on the surface of the third electric slide 18 drive the blade 192 to move to the left. At this time, the speakers 16 on both sides above the second fixed frame 15 are turned on to remind people around to prevent children or parents from contacting the blade 192. After the blade 192 has cut the drawing paper, the parents can open the first cylinders 131 on both sides, so that the first pressing plate 132 descends to press the drawing paper below, and the speakers 16 on both sides will also remind to prevent the first pressing plate 132 and the second pressing plate 133 from squeezing the children's hands, and then the children can copy and doodle according to the pattern on the drawing paper.
