[0033] See also Figure 1-3 , Figure 7A clamping assembly 6 is fixedly provided on one side of the rotating assembly 5, and the display screen 2 is clamped between the two clamping assemblies 6. The clamping assembly 6 includes an L-shaped support block 601 fixedly provided on one side of the turntable 501. Two relatively arranged clamping plates 602 are slidably provided on the L-shaped support block 601. A rubber pad is fixedly provided on one side of the clamping plate 602 clamping the display screen 2. A movable groove is provided in the L-shaped support block 601, and a bidirectional threaded rod 603 is rotatably provided in the movable groove. Two relatively arranged slide plates 604 are threadedly rotatably connected on the bidirectional threaded rod 603. A positive thread and a negative thread are provided on the bidirectional threaded rod 603, and the positive thread and the negative thread are opposite in thread. One of the slide plates 604 is provided with A positive thread hole for positive thread rotation, a reverse thread hole for reverse thread rotation is arranged on another slide plate 604, and the slide plate 604 is slidably connected with the movable groove, and the slide plate 604 is fixedly connected with the corresponding clamp plate 602, and a control component for driving the two-way threaded rod 603 to rotate is arranged on one side of the L-shaped support block 601, and the rotation of the rotation block 605 drives the two-way threaded rod 603 to rotate, and a bolt 606 is movably arranged on the rotation block 605, and one end of the bolt 606 is threadedly connected to the L-shaped support block 601, and the L-shaped support block 601 is provided with a plurality of threaded holes for the bolt 606 to be threadedly connected. Since the positive thread is threadedly connected to the positive thread hole, and the reverse thread is threadedly connected to the reverse thread hole, when the two-way threaded rod 603 rotates, it can drive the two slide plates 604 to move in opposite directions, thereby driving the two clamp plates 602 to move in opposite directions.

[0034] Working principle of the present invention:

[0035] When the height of the display screen 2 needs to be adjusted, the motor 1 307 can be started to drive the rotating rod 304 to rotate, so that the bevel gear 1 305 can be rotated, thereby driving the bevel gear 2 306 to rotate, so that the threaded rod 303 can rotate, so that the slider 302 can slide in the limiting groove 301, and then the rotating component 5 and the clamping component 6 can also be driven to move. Since the display screen 2 is clamped in the clamping component 6, the height of the display screen 2 can be adjusted.

[0036] When the angle of the display screen 2 needs to be adjusted, the display screen 2 is first adjusted upward to a suitable position, and then the handle 507 can be pulled to drive the connecting block 505 and the limiting ring 503 to move. At this time, the spring 504 is deformed, the limiting block 508 slides out of the fixed sleeve 502, and the clamping rod 506 also leaves one of the clamping slots. Then the handle 507 can be rotated to make the connecting block 505 rotate on the limiting ring 503, and the limiting block 508 also rotates, so that the limiting block 508 is limited by the fixed sleeve 502, thereby preventing the clamping rod 506 from moving due to the elastic force of the spring 504. At this time, the turntable 501 can be rotated to adjust the angle of the display screen 2. After adjusting to a suitable angle, the handle 507 can be rotated to the initial position, and then the handle 507 can be released. The elastic force of the spring 504 can pull the limit ring 503, so that the connecting block 505 can also be pulled, so that the clamping rod 506 can be clamped with another clamping slot, so that the turntable 501 can be braked to determine the angle of the display screen 2.

[0037] When the display screen 2 needs to be inspected, the bolt 606 can be rotated so that the bolt 606 leaves one of the threaded holes. At this time, the rotating block 605 can be rotated to drive the bidirectional threaded rod 603 to rotate, so that the two slides 604 move in opposite directions, thereby moving the clamping plate 602 away from the display screen 2, so that the display screen 2 is not clamped. At this time, the display screen 2 can be removed from the L-shaped support block 601 for inspection.

[0038] If the classroom demonstration interactive all-in-one machine needs to be moved, it can be moved via the universal wheel 101. After the classroom demonstration interactive all-in-one machine is moved to a suitable position, the locking structure can be activated to brake the universal wheel 101, and then the motor 2 404 can be started to drive the stabilizing bar 402 to rotate, so that the plurality of supporting foot rods 403 rotate until the supporting foot rods 403 are in contact with the ground, thereby increasing the stability of the classroom demonstration interactive all-in-one machine.

[0039] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
