In the above structure, the outer wall of the knob 10 is provided with a friction groove, and the rotation friction of the knob 10 can be enhanced through the friction groove.

[0023] In a preferred embodiment, there are two fixed blocks 6, and the two fixed blocks 6 are arranged in a straight line on the outer wall of the frame 2. The two fixed blocks 6 are threadedly connected to the threaded rod 5. In the above structure, by rotating the threaded rod 5, the threaded rod 5 drives the two fixed blocks 6 to move up and down on the outer wall of the threaded rod 5 through the thread rotation of the outer wall, thereby driving the frame 2 to move up and down.

[0024] In a preferred embodiment, the threaded rod 5 is located inside the column 7, and the inner wall size of the column 7 is adapted to the size of the fixed block 6. The fixed block 6 is located inside the column 7, and the outer wall of the fixed block 6 is fitted with the inner wall of the column 7. In the above structure, the outer wall of the fixed block 6 is fitted with the outer wall of the column 7, so that when the fixed block 6 moves up and down on the inner wall of the threaded rod 5, it will not be offset due to the rotational acceleration force of the threaded rod 5.

[0025] In a preferred embodiment, a rectangular groove is provided on the top of the protection box 1, and the size of the rectangular groove is adapted to the bottom size of the frame 2. In the above structure, the threaded rod 5 drives the fixing block 6 to move downward, so that the fixing block 6 drives the frame 2 to move downward, so that the frame 2 enters the rectangular groove inside the protection box 1, thereby allowing the protection box 1 to protect the frame 2.

[0026] In a preferred embodiment, there are two guide rails 8, and the two guide rails 8 are located on the inner wall of the frame 2 close to the two ends of the guide rails 8. The two guide rails 8 penetrate the baffle plate 9, and the two guide rails 8 are slidably connected to the baffle plate 9. In the above structure, the movement trajectory of the baffle plate 9 is limited by the two guide rails 8, so that the baffle plate 9 can only move on the outer wall of the guide rail 8.

[0027] In a preferred embodiment, the width of the movable groove 11 is the same as the diameter of the connecting rod 14, and the connecting rod 14 passes through the movable groove 11, the gear 15 is located above the tooth groove 12, and the tooth groove 12 is meshed with the gear 15. In the above structure, by rotating the knob 10, the knob 10 drives the connecting rod 14 to rotate, and the connecting rod 14 drives the tooth groove 12 to move through the meshing of the outer wall with the tooth groove 12, thereby driving the baffle plate 9 to move. When the baffle plate 9 moves, the movable groove 11 moves on the outer wall of the connecting rod 14.

[0028] Working principle: when in use, an optical image is displayed through the display screen. If the display of the display screen 3 is not clear due to the refraction of natural light, the user turns the knob 10, and the knob 10 drives the connecting rod 14 to rotate, and the connecting rod 14 drives the gear 15 to rotate. The rotation of the gear 15 drives the tooth groove 12 to move at the bottom of the gear 15, and then drives the shielding plate 9 to move on the outer wall of the guide rail 8, so that the shielding plate 9 protrudes from the inner wall of the frame 2, and then the shielding plate 9 blocks the ambient light above the display screen 3 under certain conditions, so that the actual clarity of the display screen 3 is improved. When the device is finished using, the control button 16 is pressed to start the motor 4, and the motor 4 drives the threaded rod 5 to rotate, and the two fixed blocks 6 are driven to move downward on the inner wall of the column 7 through the threads of the outer wall, and the frame 2 is driven to move downward by the downward movement of the fixed blocks 6, and the frame 2 drives the display screen 3 to move downward, so that the frame 2 is hidden in the interior of the protection box 1, and then the frame 2 and the protection box 1 cover the display screen 3 as a whole, so that the display screen 3 is no longer in contact with the outside, so that when the display screen 3 is not in use, it will not be damaged due to interference from external factors.
