[0026] A flip cover 102 close to the folding computer frame 101 is hingedly connected to the top of the drawing table 1 on one side away from the display board 2. Multiple sets of brackets are rotatably connected to the inner wall of one side of the display board 2 close to the drawing table 1. Inner slide grooves 103 are symmetrically arranged on both sides of the top of the drawing table 1. A tray frame 104 is slidably installed on the bottom of one side of the drawing table 1 close to the folding computer frame 101. Outer slide grooves 106 close to the extension bracket 401 are arranged at the bottom of both ends of the drawing table 1.

[0027] When in use, the flip cover 102 is moved to flip it outward along the edge of the drawing table 1 via the hinge, and the display board 2 is further moved to flip it outward along the edge of the drawing board via the hinge, and the foldable computer frame 101 is rotated and lifted up along one side of the flip cover 102 via the hinge. At the same time, the required drawing tools are taken out of the storage compartment 105, and then the display board 2 is temporarily reset according to the drawing needs, and the tray rack 104 is pulled out to pull out the keyboard and other tools. If it is necessary to display comparison drawings, the display board 2 is further lifted up along the hinge and fixed to the drawing table 1 with a bracket.

[0028] Embodiment 2:

[0029] This embodiment is used to solve the problem that the traditional drawing table is limited by the overall table structure during teaching, resulting in the drawing table being moved and adjusted during teaching to achieve use for demonstration and teaching, the overall process is cumbersome and inconvenient, and there is a risk of touching surrounding objects.

[0030] See also Figure 1 , Figure 3 - Figure 5 As shown, the retractable teaching drawing device of this embodiment includes a chuck 301 connected to the center bolt at the bottom of the drawing table 1 is arranged on the top of the beam frame 3, a support plate 304 is movably connected to the bottom of the chuck 301, and an adjustment plate 4 is arranged at both ends of the beam frame 3. The top of the adjustment plate 4 is rotatably connected to the extension bracket 401, and the bottom of the adjustment plate 4 is rotatably connected to the support leg 404;

[0031] A lifting cylinder 302 connected to the support plate 304 is fixedly installed in the middle of the beam 3, and a connecting flange 303 is sleeved on the outer side of the lifting cylinder 302 to abut against the bottom wall of the support plate 304; a rotary cylinder 305 is clamped and installed on the top of the support plate 304, and an electromagnetic disc 306 is clamped and installed on the top of the rotary cylinder 305. A metal protrusion 307 facing the electromagnetic disc 306 is fixedly installed at the bottom center of the chuck 301;

[0032] A rotating member 402 is sleeved and installed on the top of the extension bracket 401, and an electromagnetic slider 403 sleeved with the outer slide groove 106 is embedded on the top of the rotating member 402. Electromagnetic iron blocks are embedded inside the electromagnetic disc 306 and the electromagnetic slider 403. A telescopic cylinder is embedded inside the extension bracket 401. A limit rod 406 is rotatably connected between the inner walls of the top of the support leg 404, and a limit bolt 405 is embedded at the tip of the limit rod 406.

[0033] If the drawing table 1 needs to be smoothly unfolded, the lifting cylinder 302 drives the chuck 301 to lift the drawing table 1 to a specified height, and at the same time, the telescopic cylinder drives the extension bracket 401 to extend, and the extension bracket 401 drives the electromagnetic slider 403 to slide along the inner side of the outer slide groove 106, so as to simultaneously lift the drawing table 1 smoothly, and the locking between the limit rod 406 and the support leg 404 is released by turning the limit bolt 405, and the angle between the support legs 404 is further adjusted to complete the height adjustment of the overall drawing device, and then the limit rod 406 is turned close to the notch on the inner wall of the support leg 404. When the limit rod 406 is close to the notch, the limit bolt 405 is turned until the limit rod 406 docks with the notch and then the external force on the limit bolt 405 is released;

[0034] If the drawing table 1 needs to be supported and rotated in one direction, the telescopic cylinder drives the electromagnetic slider 403 to disengage from the outer slide groove 106, and the electromagnetic disc 306 is energized to generate magnetic force, which electromagnetically adsorbs the metal protrusion 307 on the support disc 304, and the rotary cylinder 305 drives the electromagnetic disc 306 and the chuck 301 to rotate synchronously, which drives the drawing table 1 to rotate synchronously.

[0035] Combining the first embodiment and the second embodiment, it is possible to implement foldable storage and upright flipping of teaching computers or display screens, and it is also convenient to clip teaching drawing drawings on the display board 2, which is convenient for on-site comparative teaching guidance. The electromagnetic adsorption active connection between the chuck 301 and the support plate 304 can be used to facilitate the flexible rotation and disassembly and assembly of the beam frame 3 to the drawing table 1. The extension bracket 401 is used to adjust the distance between multiple groups of electromagnetic sliders 403, and the electromagnetic adsorption active connection between the electromagnetic slider 403 and the outer slide groove 106. The limit rod 406 is combined to adjust the angle between the support legs 404 to form a multiple telescopic height limit adjustment up and down. At the same time, the beam frame 3 and the adjustment plate 4 cooperate to support the drawing table 1 to form a multiple stable support structure. The single beam frame 3 constitutes a rotation support structure for the drawing table 1, and the single adjustment plate 4 constitutes a multi-point positioning support structure for the drawing table 1.
