[0021] It should be noted that due to the problem of insufficient stability of existing preschool education drawing boards, they often tip over, and the angle adjustment is not convenient enough in actual use. In this solution, the rotating block 25 drives the slide rod 23 to move upward so that a vacuum is formed in a certain space between the bottom of the suction cup 24 and the ground, thereby fixing the device to the ground through the lower frame 11 to prevent the device from tipping over, and the rotation angle of the drawing board 13 is adjusted by controlling the engagement of the fixed card block 32 with the rotating card block 31.

[0022] Specifically, in this embodiment, the scheme mainly includes a support mechanism 1, a plurality of fixers 2 are provided at the bottom of the support mechanism 1, a limiting mechanism 3 is provided inside the support mechanism 1, and the slide bar 23 is slid until the slide bar 23 drives the suction cup 24 to fit the ground. At this time, the rotating block 25 is rotated to rotate the rotating block 25 around the end of the slide bar 23. Since the connection between the rotating block 25 and the slide bar 23 is located at the eccentric part of the rotating block 25, when the rotating block 25 rotates, the rotating block 25 will drive the slide bar 23 to move upward, so that a vacuum is formed in a certain space between the bottom of the suction cup 24 and the ground, so that the suction cup 24 and the ground are fixed to each other, and the rotating block 25 is framed downward by the pad 22. The frame 11 applies downward pressure, fixes the device to the ground through the lower frame 11, pulls the driving block 35, and slides outward through the driving block 35 to drive the movable rod 33 and the fixed block 32 away from the rotating block 31. At this time, the spring 34 will be compressed by the fixed block 32 and the inside of the mounting hole 16, and the rotating block 31 will rotate inside the mounting hole 16, thereby adjusting the angle of the drawing board 13. When the angle adjustment of the drawing board 13 is completed, the spring 34 drives the fixed block 32 to engage with the rotating block 31, and the rotating block 31 is fixed to the inside of the mounting hole 16 through the fixed block 32, thereby fixing the drawing board 13 between the two support frames 12.

The protective plate 21 is fixedly connected to the inside of the fixing hole 14, and the bottom of the cushion block 22 is in contact with the top of the lower frame 11. After the lower frame 11 is placed, the sliding rod 23 is slid until the sliding rod 23 drives the suction cup 24 to contact the ground. At this time, the rotating block 25 is rotated to make the rotating block 25 rotate around the end of the sliding rod 23. Since the connection between the rotating block 25 and the sliding rod 23 is located at the eccentric part of the rotating block 25, when the rotating block 25 rotates, the rotating block 25 will drive the sliding rod 23 to move upward, so that a vacuum is formed in a certain space between the bottom of the suction cup 24 and the ground, so that the suction cup 24 and the ground are fixed to each other, and the rotating block 25 applies downward pressure to the lower frame 11 through the cushion block 22, and fixes the device to the ground through the lower frame 11.

The rotating block 31 is rotatably connected to the inside of the mounting hole 16, and the two ends of the spring 34 are respectively fixedly connected to the fixed block 32 and the inside of the mounting hole 16. The driving block 35 is fitted with the outer side of the support frame 12. First, pull the driving block 35 , the driving block 35 slides outward to drive the movable rod 33 and the fixed block 32 away from the rotating block 31. At this time, the spring 34 will be compressed by the fixed block 32 and the inside of the mounting hole 16, and the rotating block 31 will rotate inside the mounting hole 16, thereby adjusting the angle of the drawing board 13. When the angle adjustment of the drawing board 13 is completed, the spring 34 drives the fixed block 32 to engage with the rotating block 31, and the rotating block 31 is fixed to the inside of the mounting hole 16 by the fixed block 32, thereby fixing the drawing board 13 between the two support frames 12.
