[0025] Working principle: When the angle of the drawing board 8 needs to be adjusted, the servo motor 191 can be started by the controller 20 to drive the driving bevel gear 192 to rotate, and then the first threaded rod 12 is driven to rotate through the driven bevel gear 193. The first threaded rod 12 will drive the moving block 13 to move upward during the rotation, and then the slider 18 is used to drive the drawing board 8 to rotate clockwise around the top of the support block 9, so as to adjust the angle of the drawing board 8, so that the draftsman can adjust the angle of the drawing board 8 according to his own drawing habits, thereby facilitating the use of the draftsman. Secondly, when the drawing table needs to be adjusted, When the height of the drawing table is adjusted, the controller 20 can start the dual-axis servo motor 241 to drive the two worms 242 to rotate, and then the two threaded sleeves 22 are driven to rotate through the two worm wheels 243. During the rotation of the two threaded sleeves 22, the two second threaded rods 23 are driven to move upward, and then the horizontal plate 7 and the drawing board 8 are driven to move upward as a whole, so as to adjust the height of the drawing table, so that the draftsman can adjust the height of the drawing board 8 according to his or her height, thereby further facilitating the use of the draftsman. After the adjustment is completed, the draftsman can use the drawing board 8 to perform sketching and painting.

[0026] In summary, the multifunctional lifting sketching and drawing table starts the servo motor 191 to drive the driving bevel gear 192 to rotate, and then drives the first threaded rod 12 to rotate through the driven bevel gear 193. The first threaded rod 12 will drive the moving block 13 to move upward during the rotation, and then drive the drawing board 8 to rotate clockwise around the top of the support block 9 through the slider 18, so as to adjust the angle of the drawing board 8, so that the draftsman can adjust the angle of the drawing board 8 according to his own drawing habits, thereby facilitating the use of the draftsman. Secondly, the dual-axis servo motor 241 is started to drive the two worms 242 to rotate, and then the two worm gears 243 are used to drive the two worm gears 243 to rotate. The threaded sleeves 22 rotate, and the two threaded sleeves 22 drive the two second threaded rods 23 to move upward during the rotation, and then drive the cross plate 7 and the drawing board 8 to move upward as a whole, so as to adjust the height of the drawing table, so that the draftsman can adjust the height of the drawing board 8 according to his own height, thereby further facilitating the use of the draftsman, and solving the problem that the existing drawing tables are mostly unadjustable in actual use and the height of the drawing tables is fixed, resulting in the draftsman being unable to adjust the angle of the drawing board according to his own drawing habits, and unable to adjust the height of the drawing table according to his own height, which is not conducive to use.
