[0016] To make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Identical parts are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0017] like Figure 1 and Figure 4 As shown, a magic TV screen includes a main screen 1, and extended screens 2 are provided on both sides of the main screen 1. Grooves 16 are provided on both sides of the main screen 1 and the inner ends of the two extended screens 2. Magnetic blocks A23 are provided in the two grooves 16 on both sides of the main screen 1. The two magnetic blocks A23 are connected to the main screen 1 through wires 17. A magnetic block B24 is provided in the groove 16 located on the extended screen 2, and the magnetic block B24 is connected to the extended screen 2 through wires 17. A shell 3 is provided on the rear side of the main screen 1, and a screw 9 is provided in the shell 3. A threaded block 11 is provided on the threaded sleeve on the surface of the screw 9. Support rods 5 are provided on both sides of the threaded block 11, and one side of the two support rods 5 is connected to the rear sides of the two extended screens 2 respectively through a connecting rod 8.

[0018] A motor 10 is provided in the housing 3. The output end of the motor 10 is connected to a screw 9. The other end of the screw 9 is rotatably connected to the inner cavity of the housing 3. Openings 4 are provided on both sides of the housing 3. Two connecting rods 8 pass through the two openings 4 respectively. Sliding grooves 7 are provided at the two openings 4. Sliding blocks 6 are provided to slide in the two sliding grooves 7. The two sliding blocks 6 are respectively connected to the two support rods 5, driving the extension screen 2 to move. A sleeve rod 12 is provided on the surface of the two support rods 5. Slide grooves 14 are provided on both sides of the inner cavity of the two sleeve rods 12. Slide blocks 15 are provided to slide in the two slide grooves 14. The two slide blocks 15 are respectively fixedly connected to the two sides of the support rods 5. A spring 13 is provided on one side of the two support rods 5. The two springs 13 are respectively located in the two sleeve rods 12. The two sleeve rods 12 are fixedly connected to the two sides of the threaded block 11, making the movement more stable.

[0019] The magnetic block A23 cooperates with the magnetic block B24. Slots 19 are opened on both sides of the groove body 16. Slide rods 20 are fixed in the two slots 19. Moving blocks 21 are slidably sleeved on the surfaces of the two slide rods 20. Reset springs 18 are sleeved on the surfaces of the two slide rods 20. The two reset springs 18 are respectively located on one side of the two moving blocks 21. One side of the two moving blocks 21 is fixedly connected with a connecting rod 22. The two connecting rods 22 are both connected to the magnet to energize the extended screen 2.

[0020] This device can be controlled by voice, mobile phone APP, and remote control, making it more convenient to use.

[0021] During use, the user can send an adjustment signal through voice commands, mobile phone APP or remote control. After receiving the signal, the motor 10 starts, driving the screw 9 to rotate clockwise, and the threaded block 11 moves on the screw 9 due to the threaded transmission, thereby pushing the support rods 5 on both sides to move synchronously. When the spring 13 causes the support rod 5 to slide in the sleeve rod 12 through elastic force, the slider 15 moves along the slide groove 14 to ensure smooth movement. The support rod 5 drives the extended screen 2 to move horizontally along the sliding groove 7 at the opening 4 through the connecting rod 8. When the magnetic block B24 on the inside of the extended screen 2 is aligned with the magnetic blocks A23 on both sides of the main screen 1, the two are attached due to magnetic adsorption, and at the same time, the wire 17 connects the circuit, so that the extended screen 2 and the main screen 1 form a complete display screen, realizing screen size expansion; if the screen needs to be reduced, the motor 10 rotates in the opposite direction, the threaded block 11 drives the extended screen 2 to retract, the magnetic block separates, and the reset spring 18 pushes the moving block 21 to reset the magnetic block, and the screen returns to its initial state, ensuring the smoothness and stability of screen adjustment.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
