[0029] Through the above technical scheme, by starting the first motor 301, the first screw rod 302 can be driven to rotate and the two moving blocks 303 can be driven to move at the same time. Since the threads on both sides of the first screw rod 302 rotate in opposite directions, the two moving blocks 303 can move relative to each other, driving the two movable plates 305 on the connecting shaft 304 to rotate in opposite directions. Under the mutual restraint of the movable plates 305, the mounting frame 2 can be lifted up and down. When not in use, the mounting frame 2 can be lowered into the protective box 1 to avoid direct collision with the outside world. When in use, it can be extended out for demonstration, thereby achieving the effect of protecting the display screen 6 on the demonstration device.

[0030] Specifically, the bottom of the protection box 1 is fixedly connected to the base 4, and the bottom of the base 4 is equipped with a universal wheel 5, the interior of the mounting frame 2 is provided with a display screen 6, and the top of the mounting frame 2 is fixedly connected to the top of the top plate 7.

[0031] Through the above technical solution, the universal wheels 5 at the bottom of the base 4 can facilitate the movement of the entire demonstration device to an arbitrary position for easy display. The content and projects of the software development can be displayed on the display screen 6 so that the viewer can see them at a glance. The top plate 7 can protect the top of the mounting frame 2.

[0032] Specifically, the first motor 301 forms a moving structure through the first screw rod 302 and the moving block 303 , and the external thread of the first screw rod 302 matches the internal thread of the moving block 303 .

[0033] Through the above technical solution, it is convenient for the first motor 301 to drive the moving block 303 to move during the process of driving the first screw rod 302 to rotate, because the threads on both sides of the first screw rod 302 have opposite rotation directions, and the two moving blocks 303 are symmetrically arranged on both sides of the first screw rod 302, so that the two moving blocks 303 can move relative to each other, achieving the effect of the two moving blocks 303 moving in opposite directions.

[0034] Specifically, the moving block 303 forms a rotating structure with the movable plate 305 via the connecting shaft 304 , and the connecting shaft 304 is disposed between the moving block 303 and the movable plate 305 , and the top of the movable plate 305 is connected to the bottom of the mounting frame 2 .

[0035] Through the above technical solution, the moving block 303 can drive the movable plate 305 on the connecting shaft 304 to rotate during the movement, and the movable plate 305 rotates in the opposite direction under the action of the moving block 303, so that the mounting frame 2 is driven to rise and fall under the mutual restraint of the two movable plates 305, thereby achieving the effect of lifting and lowering the mounting frame 2.

[0036] Specifically, the protective box 1 forms a sliding structure through the movable groove 306 and the movable block 307 , and the shape and size of the movable block 307 match the shape and size of the movable groove 306 , and one side of the movable block 307 is connected to one side of the mounting frame 2 .

[0037] Through the above technical solution, the mounting frame 2 can slide in the movable groove 306 and remain stable through the movable block 307 during the lifting process, and the movable block 307 can limit the range of the mounting frame 2 from sliding out of the protective box 1, playing a certain limiting role.

[0038] Specifically, the second motor 801 forms a lifting structure with the lifting block 803 through the second screw rod 802 , and the external thread of the second screw rod 802 matches the internal thread of the lifting block 803 .

[0039] Through the above technical solution, it is convenient to start the second motor 801 to drive the second screw rod 802 to rotate and drive the lifting block 803 to move up and down at the same time, thereby achieving the lifting effect of the lifting block 803.

[0040] Specifically, the lifting plate 804 forms a snap-fit ​​structure with the cleaning plate 806 through the mounting groove 805 , and the shape and size of the mounting groove 805 match the shape and size of the cleaning plate 806 .

[0041] Through the above technical solution, the lifting block 803 can be lifted and lowered to drive the lifting plate 804 to lift and lower synchronously. The cleaning plate 806 can clean the display screen 6 during the lifting and lowering of the lifting plate 804, and the cleaning plate 806 can be pulled out from the installation slot 805 for replacement, thereby achieving the effect of automatically cleaning the display screen 6.

[0042] Working principle: When using the software to develop a demonstration device, first, when protecting the display screen 6 on the mounting frame 2, it is only necessary to start the first motor 301, and the first motor 301 drives the first screw rod 302 to rotate, and the first screw rod 302 drives the moving block 303 to move. Because the threads on both sides of the first screw rod 302 rotate in opposite directions, the two moving blocks 303 move relative to each other, and then the two moving blocks 303 drive the two movable plates 305 to rotate in opposite directions through the connecting shaft 304, so that the mounting frame 2 is lifted and lowered under the mutual restraint of the two movable plates 305, so that the mounting frame 2 is lowered into the protection box 1 The interior is protected. When cleaning the display screen 6, it is only necessary to start the second motor 801. The second motor 801 drives the second screw rod 802 to rotate, which drives the lifting block 803 to move up and down. The lifting block 803 moves up and down, which drives the lifting plate 804 to move up and down. Then, during the lifting process of the lifting plate 804, the cleaning plate 806 will clean the display screen 6, and the cleaning plate 806 can be pulled out from the installation slot 805 for replacement, thereby completing the automatic cleaning of the display screen 6. This completes all the work. The contents not described in detail in this manual belong to the prior art known to professional and technical personnel in this field.
