[0022] The lifting device 2 includes a screw 201, a threaded block 202, a fixed rod 203, an inclined block 204, a limit block 207 and a support block 206. The screw 201 is movably installed inside the control box 1, the external thread of the screw 201 is connected to the threaded block 202, the top of the threaded block 202 is fixedly installed with the fixed rod 203, the top of the fixed rod 203 contacts the inclined block 204, the top of the control box 1 is fixedly installed with the support block 206, the inside of the support block 206 is fixedly connected with an elastic rope 205, the elastic rope 205 is fixedly connected to the drawing board 3, and the limit block 207 is fixedly installed on the top of the control box 1.

[0023] The moving device 5 includes a dual-axis motor 501, a threaded sleeve 502, a screw rod 503, a movable block 504, a slider 505, a hinged rod 506 and a universal wheel 507. The dual-axis motor 501 is fixedly installed at the bottom of the control box 1, and the output shaft of the dual-axis motor 501 is fixedly installed with a threaded sleeve 502. The internal thread of the threaded sleeve 502 is connected with the screw rod 503. The movable block 504 is movably installed outside the screw rod 503. The top of the movable block 504 is fixedly installed with a slider 505. The bottom of the movable block 504 is hinged with a hinged rod 506. The bottom of the control box 1 is provided with a universal wheel 507. The output shafts on both sides of the dual-axis motor 501 simultaneously drive the two threaded sleeves 502 to rotate, so that the screw rod 503 The movable block 504 moves left and right in the threaded sleeve 502, and is driven to move by the screw rod 503. When the movable block 504 moves in the direction away from the dual-axis motor 501, the hinged rod 506 at the bottom moves downward to drive the universal wheel 507 to fit the ground. The slider 505 at the top of the movable block 504 is slidably connected to the slide groove to limit the movement of the movable block 504. The universal wheel 507 is provided to facilitate the movement of the drawing device. When the drawing device needs to be stationary, when the movable block 504 moves in the direction close to the dual-axis motor 501, the hinged rod 506 at the bottom moves upward to drive the universal wheel 507 to separate from the ground. The universal wheel 507 is retracted, and the baffle 4 can be used to keep the drawing device stationary.

[0024] When implementing, follow these steps:

[0025] 1) First, rotate the screw 201;

[0026] 2) Then adjust the drawing board 3 to a suitable angle;

[0027] 3) Finally, the drawing device is driven to move by the universal wheel 507.

[0028] In summary, the drawing device for visual drawing drives the two threaded sleeves 502 to rotate simultaneously through the output shafts on both sides of the dual-axis motor 501, so that the screw rod 503 moves left and right in the threaded sleeve 502, and the movable block 504 is driven to move by the screw rod 503. When the movable block 504 moves in the direction away from the dual-axis motor 501, the hinged rod 506 at the bottom moves downward to drive the universal wheel 507 to fit the ground. The slider 505 at the top of the movable block 504 is slidably connected with the slide groove to limit the movement of the movable block 504. The movement of the drawing device is facilitated by providing the universal wheel 507. When the drawing device needs to be stationary, when the movable block 504 moves in the direction close to the dual-axis motor 501, the hinged rod 506 at the bottom moves upward to drive the universal wheel 507 to separate from the ground, and the universal wheel 507 is folded up, so that the drawing device can be kept stationary by the baffle 4.

[0029] In addition, the visual drawing device is provided with a screw rod 201. Manual rotation of the screw rod 201 can drive the threaded block 202 to move left and right. The movement of the fixed rod 203 causes the inclined block 204 to start moving until the inclined block 204 lifts the drawing board 3, and the angle of the drawing board 3 can be adjusted. When the designer is drawing, the drawing board 3 can be adjusted according to different needs, making the use of the drawing device more convenient, solving the problem that when the drawings on the drawing device need to be displayed, it is too troublesome to move the drawing device, and the existing drawing device cannot adjust the angle of the drawing board.
