Grooves are provided on the sides of the two lifting slides away from each other, and toggling tooth plates are provided in the grooves. Extension plates are provided on the sides of the two lifting slides close to each other, and three fixing columns are provided on the sides of the two extension plates close to each other. Telescopic columns are provided on the sides of the fixed columns not connected to the extension plates, and fixed plates are provided on the sides of the telescopic columns not contacting the fixed columns.

[0034] The two first sliders 8 are fixedly connected to the adjacent sides with mounting plates 19, and one side of one mounting plate 19 is fixedly connected to the second motor 4. The output end of the second motor 4 is fixedly connected to the first rotating shaft 9, which is arranged horizontally, and the other end of the first rotating shaft 9 is rotatably connected to the other mounting plate 19.

[0035] A fixing block 21 is fixedly sleeved on the middle of the first rotating shaft 9 , and the display screen 7 is fixedly connected to the side surface of the fixing block 21 .

[0036] A driving assembly is provided on the base 2 , and the driving assembly drives the two first screw rods 6 to rotate synchronously.

[0037] The driving assembly includes a first motor 1, which is fixedly connected to one side of the base 2. The output end of the first motor 1 is fixedly connected to a second shaft 16, which is rotatably connected to the inside of the base 2, and the second shaft 16 corresponds to the two first screw rods 6 up and down.

[0038] The base 2 is provided with two symmetrical second grooves 17, which are respectively located at two ends of the second rotating shaft 16. The second rotating shaft 16 passes through the two second grooves 17, and the bottom end of the first screw rod 6 extends downward into the corresponding second groove 17.

[0039] The bottom ends of the first screw rods 6 are fixedly connected to the second bevel gears 14 , and the second rotating shafts 16 in the second grooves 17 are fixedly sleeved with third bevel gears 15 , which are meshed with the corresponding second bevel gears 14 .

[0040] The bottom surface of the base 2 is provided with two symmetrical receiving grooves 20, which are respectively located on both sides of the second groove 17. A support plate 10 is slidably arranged inside each receiving groove 20, and the bottom surface of the support plate 10 is flush with the bottom surface of the base 2.

[0041] A transmission assembly is provided on the base 2, and the transmission assembly cooperates with the lifting assembly. When the display screen 7 moves up and down, the transmission assembly drives the two support plates 10 to move away from each other or towards each other.

[0042] The transmission assembly includes four second screw rods 11, and two corresponding side walls of the receiving groove 20 are provided with slide grooves 12. Two of the slide grooves 12 are respectively located on both sides of one of the second grooves 17, and the other two slide grooves 12 are respectively located on both sides of another second groove 17.

[0043] The four second screw rods 11 are rotatably connected to the corresponding slide grooves 12 respectively. The two sides of the support plate 10 are fixedly connected with movable plates 18. The movable plates 18 are respectively threadedly sleeved on the corresponding second screw rods 11, and the movable plates 18 are slidably connected to the corresponding slide grooves 12.

[0044] A transmission member is provided on the base 2 , and the transmission member drives the second screw rod 11 to rotate.

[0045] The transmission member includes four first bevel gears 13 . One end of the second screw rod 11 is rotatably connected to the inner wall of the slide slot 12 . The other end of the second screw rod 11 rotates through the end surface of the slide slot 12 and then extends into the corresponding second groove 17 .

[0046] The first bevel gears 13 are respectively fixedly connected to one end of the second screw rod 11 extending into the second groove 17 , and the first bevel gears 13 are meshed with the corresponding third bevel gears 15 . The first bevel gears 13 are not in contact with the second bevel gears 14 .

[0047] Working principle:

[0048] When the height of the display screen 7 needs to be raised, the first motor 1 is started to rotate the output shaft of the first motor 1 forwardly. The second rotating shaft 16 rotates, the two third bevel gears 15 rotate, drive the second bevel gear 14 to rotate, and the first screw rod 6 rotates.

[0049] The first screw rod 6 rotates in the corresponding first slider 8, and the first slider 8 moves upward in the corresponding first groove 5, driving the mounting plate 19 and the first rotating shaft 9 to move upward, so that the display screen 7 moves upward.

[0050] When the third bevel gear 15 rotates, it drives the corresponding first bevel gear 13 to rotate, so that the second screw 11 rotates. Since the third bevel gear 15 is meshed with the two first bevel gears 13 respectively, the two first bevel gears 13 rotate in opposite directions, so the second screws 11 located on both sides of the second groove 17 rotate in opposite directions, so that the moving plates 18 on the two support plates 10 move in opposite directions. The moving plates 18 slide in the corresponding slide grooves 12, driving the support plates 10 to slide in the corresponding receiving grooves 20, and the two support plates 10 move in opposite directions.

[0051] When the display screen 7 moves upward, the support plate 10 will extend to the outside of the base 2, increasing the contact range with the ground, lowering the center of gravity of the entire device and increasing stability.

[0052] On the contrary, when the height of the display screen 7 needs to be lowered, the first motor 1 is started to reverse the output shaft of the first motor 1. The first screw rod 6 is also driven to rotate, so that the first slider 8 slides downward, driving the display screen 7 to move downward.

[0053] The second screw rod 11 is also driven to rotate, so that the movable plates 18 slide toward the side close to the second rotating shaft 16 , and the two supporting plates 10 move toward each other, so that the center of gravity of the entire device is adjusted with the height of the display screen 7 .

[0054] After the height of the display screen 7 is adjusted, the second motor 4 is started to rotate the first rotating shaft 9, so that the fixing block 21 rotates, and the display screen 7 is driven to rotate, so that the inclination angle of the display screen 7 is adjusted.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
