[0023] The drawing board device 7 has been specifically disclosed in the patent publication number CN217541924U, and will not be described in detail here.

[0024] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the positioning mechanism 4 includes a plurality of positioning holes 401, and the plurality of positioning holes 401 are evenly distributed on the movable plate 3 at upper and lower intervals. The positioning holes 401 are located at the upper front side of the column 2 and are fixedly connected to a fixed cylinder 402. A positioning rod 403 is slidingly arranged in the fixed cylinder 402 and matches the positioning hole 401. A limiting ring 404 is fixedly connected to the outside of the positioning rod 403. The positioning rod 403 slides in the fixed cylinder 402 through the limiting ring 404. A spring 405 is fixedly installed in front of the limiting ring 404 in the fixed cylinder 402, and the spring 405 is sleeved on the outside of the positioning rod 403.

[0025] During use, under the limited rotation of the first limiting shaft 302 and the second limiting shaft 501, the drawing board device 7 can maintain the working angle, and at the same time, by pulling the positioning rod 403, the positioning rod 403 slides in the fixed cylinder 402 through the limiting ring 404, and then squeezes the spring 405. When the positioning rod 403 slides to the positioning hole 401 and disengages, it is convenient to slide the movable plate 3 in the installation groove 201, so as to facilitate the adjustment of the height of the drawing board device 7 according to the usage situation, and again through the elastic force of the spring 405, the positioning rod 403 is reset to limit the positioning hole 401, and then the height adjustment position is positioned to improve the practicality of the device.

[0026] According to the above working process, it can be known that: through the positioning mechanism 4, when the drawing board device 7 is used, the height position of the movable board 3 can be adjusted and positioned according to the height of the user, so as to facilitate use and improve the practicality of the device.

[0027] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the storage mechanism 6 includes a sliding frame 601, which is slidably sleeved on the outside of the column 2, and a fastening bolt 602 is threadedly connected to the front side of the sliding frame 601.

One end of the outer side of the sliding rod 604 is fixedly connected to a limiting block 606, and the fastening bolt 602 is threaded through the sliding frame 601 and contacts the surface of the column 2. Two sliding rods 604 are provided in the sliding groove 603, and the two sliding rods 604 are symmetrically arranged on the left and right.

[0028] During use, by loosening the fastening bolts 602, the sliding frame 601 slides on the column 2, so that it is convenient to slide the slide rod 604 in the slide groove 603 by pulling the limit block 606, thereby releasing the limit on the corner of the drawing board device 7. At the same time, by flipping the drawing board device 7, it is flipped to the back side of the column 2. At this time, by sliding the sliding frame 601 and pulling the limit block 606, under the tension of the tension spring 605, the limit block 606 can limit the drawing board device 7, thereby facilitating the transportation of the entire device through the carrying handle 303, thereby improving its convenience in use.

[0029] This solution has the following working process: when this device is used, by loosening the fastening bolts 602, the sliding frame 601 slides on the column 2, so that it is convenient to slide the slide rod 604 in the slide groove 603 by pulling the limit block 606, and release the limit on the corner of the drawing board device 7, so that the drawing board device 7 can be rotated by the second limit shaft 501, and the connecting block 5 is limited and rotated by the first limit shaft 302. Under the limited rotation of the first limit shaft 302 and the second limit shaft 501, the drawing board device 7 can maintain the working angle, and at the same time, by pulling the positioning rod 403, the positioning rod 403 slides in the fixed cylinder 402 through the limit ring 404, thereby squeezing the spring 405. When the positioning rod 403 is pulled, the positioning rod 403 is pulled to slide in the fixed cylinder 402 through the limit ring 404, thereby squeezing the spring 405. When the rod 403 slides and disengages from the positioning hole 401, it is convenient to slide the movable plate 3 in the installation groove 201, so as to facilitate the adjustment of the height of the drawing board device 7 according to the usage situation, and again through the elastic force of the spring 405, the positioning rod 403 is reset to limit the positioning hole 401, and then the height adjustment position is positioned to improve the practicality of the device. At the same time, by flipping the drawing board device 7, it is flipped to the rear side of the column 2. At this time, by sliding the slide frame 601 and cooperating with the pulling of the limit block 606, under the pulling force of the tension spring 605, the limit block 606 can limit the drawing board device 7, and then it is convenient to carry the entire device through the carrying handle 303, thereby improving its convenience of use.

[0030] In summary: through the provided positioning mechanism 4, when the drawing board device 7 is used, the height position of the movable plate 3 can be adjusted and positioned to match the height of the user, so as to facilitate use and improve the practicality of the device; through the provided storage mechanism 6, after the use of the device is completed, the drawing board device 7 can be flipped and stored, so that the entire device can be stored and carried, thereby improving the convenience of using and carrying the device.
