Two groups of the moving blocks are respectively fixedly connected to two groups of the stable seat blocks at corresponding positions.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Move the device to the place where it is needed. When the angle of the display body needs to be adjusted, start the driving motor inside the bottom cavity seat. After the driving motor is turned on, it drives the first bevel gear, the second bevel gear and the rotating rod to rotate, and then the rotating rod drives the turntable, the driving component, the support table and the display body to rotate. When the display body is rotated and adjusted to a suitable position and angle, turn off the driving motor in the bottom cavity seat. This operation facilitates the display of the picture on the display body to be displayed at multiple angles; when the user needs to adjust the height of the display body, the user can start two sets of driving components, and multiple sets of connecting rod components jointly move the support table upward or downward, and then the support table drives the display to adjust the height. When the user adjusts the display body to a suitable height, the two sets of first motor working modes can be turned off. This setting allows the display body to work in conjunction with the bottom cavity seat and the adjustment component, so that the user can easily adjust the height of the display body and at the same time facilitate the multi-angle rotation adjustment of the display body, so that the device meets the needs of more users and improves the scope of use of the device;

[0019] 2. After the height of the display body is adjusted by the cooperative driving of the two sets of first positive and negative screw rods and other components, in order to make the support more stable after the support platform is adjusted, the two sets of first positive and negative screw rods need to be locked and limited, and the two sets of second motors are turned on. The second motor drives the second positive and negative screw rods to rotate forward, and the second positive and negative screw rods drive the two sets of fixed plates to move closer to each other, and then the multiple sets of card blocks all move closer to the ratchet component until the two sides of the ratchet component are clamped and fixed by the multiple sets of card blocks, so that the two sets of fixed plates lock the ratchet component, so that the ratchet component and the first positive and negative screw rods cannot rotate inside the turntable, so that the driving component and the support platform remain in a more stable state, preventing the display body from shifting in position;

[0020] 3. When the two sets of second motors drive the two sets of second positive and negative screws to rotate in opposite directions, the two sets of fixed plates move away from each other until the multiple sets of card blocks are completely away from the ratchet component, the ratchet component and the first positive and negative screws lose the lock, and the ratchet component is restored to a free state, and then the two sets of driving components can be in the driving adjustment mode again. This setting adds a locking mechanism on one side of the lifting drive mechanism, so that the support platform can maintain a stable state after adjusting the lifting, thereby improving the safety of the device;

[0021] 4. The present invention adds an extension component at the bottom of the bottom cavity seat. When the bottom cavity seat needs to be placed on the ground more stably for work, the third motor is turned on, the third motor drives the connecting rod to rotate forward, the connecting rod drives the fifth bevel gear to rotate forward, the fifth bevel gear drives the two groups of sixth bevel gears to rotate, and then the two groups of first screw rods rotate and the two groups of first screw rods rotate in opposite directions, and then the two groups of moving blocks move away from each other along the horizontal direction of the first screw rod, and the two groups of stable seat blocks move away from each other at the same time until the two groups of stable seat blocks are completely extended out of the bottom cavity seat. The addition of the two groups of stable seat blocks increases the floor area of ​​the device base, thereby lowering the center of gravity of the device, and then making the device more stably placed on the ground, making the display body more stable when in use;

[0022] 5. When this method is not needed, in order to prevent the two groups of stable seat blocks from occupying the effective area, the third motor drives the connecting rod to rotate in the opposite direction, so that the two groups of moving blocks move closer to each other, so that the two groups of stable seat blocks are completely retracted into the bottom cavity seat. This setting can improve the stability of the bottom of the device by expanding the components and improve the working efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Specific as Figure 9-10 As shown, the extension component 2 also includes a fifth bevel gear 231 fixedly connected to one end of the connecting rod 23, and the fifth bevel gear 231 is meshedly connected to the sixth bevel gear 251 on both sides, and the first screw rod 25 is fixedly connected to one side of the sixth bevel gear 251, and the two groups of first screw rods 25 are rotatably connected to the bottom of the bottom cavity seat 1, and the outer periphery of the first screw rod 25 is threadedly connected to the moving block 24, and the moving block 24 is slidably connected to the bottom of the bottom cavity seat 1, and the two groups of moving blocks 24 are respectively fixedly connected to the two groups of stable seat blocks 21 at corresponding positions.

[0044] Working principle: move the device to the place where it is needed. When the angle of the display body 4 needs to be adjusted, start the driving motor inside the bottom cavity seat 1. After the driving motor is turned on, it drives the first bevel gear 11, the second bevel gear 12 and the rotating rod 13 to rotate, and then the rotating rod 13 drives the turntable 32, the driving component 33, the support platform 31 and the display body 4 to rotate. When the display body 4 is rotated and adjusted to a suitable position angle, turn off the driving motor in the bottom cavity seat 1. This operation facilitates the display body 4 to be displayed at multiple angles; when the user needs to adjust the height of the display body 4, the user can start the two sets of driving components 33, the two sets of first motors 332 are turned on, the first motor 332 rotates forward or reversely, and the first motor 332 drives the fourth bevel gear 3342 and the third bevel gear 3341 to rotate, and then the first forward and reverse screw rod 331 can rotate forward or reversely. At this time, the two sets of driving components 33 The movable parts 33 will move towards or away from each other, and then the two adjacent connecting blocks 334 at the bottom will move towards or away from each other. When the two connecting blocks 334 move towards each other, the multiple connecting rod parts 336 jointly lift the support platform 31 upward, and then the support platform 31 drives the display body 4 to rise; when the two connecting blocks 334 move away from each other, the multiple connecting rod parts 336 jointly lower the support platform 31 downward, and then the support platform 31 drives the display body 4 to descend. When the user adjusts the display body 4 to a suitable height, the working modes of the two first motors 332 can be turned off. This arrangement allows the display body 4 to cooperate with the bottom cavity seat 1 and the adjustment component 3, and the user can conveniently adjust the height of the display body 4, and at the same time, it is convenient to rotate and adjust the display body 4 at multiple angles, so that the device can meet the needs of more users and improve the scope of use of the device.

[0045] After the height of the display body 4 is adjusted by the cooperative driving of the two sets of first positive and negative screw rods 331 and other components, in order to make the support of the support platform 31 more stable after adjustment, it is necessary to lock and limit the two sets of first positive and negative screw rods 331, turn on the two sets of second motors 3371, and the second motors 3371 drive the second positive and negative screw rods 3374 to rotate forward, and the second positive and negative screw rods 3374 drive the two sets of fixing plates 3372 to move closer to each other, and then the multiple sets of card blocks 3373 all move closer to the ratchet component 337, until the two sides of the ratchet component 337 are clamped and fixed by the multiple sets of card blocks 3373, so that the two sets of fixing plates 3372 lock the ratchet component 337, then the ratchet component 337 and the first positive and negative screw rods 33 1 cannot rotate inside the turntable 32, thereby keeping the driving component 33 and the support platform 31 in a more stable state, preventing the display body 4 from being displaced; when the two sets of second motors 3371 drive the two sets of second positive and negative screw rods 3374 to rotate in the opposite direction, the two sets of fixing plates 3372 move away from each other until the multiple sets of card blocks 3373 are completely away from the ratchet component 337, the ratchet component 337 and the first positive and negative screw rods 331 lose the lock, and the ratchet component 337 is restored to a free state, and then the two sets of driving components 33 can be in the driving adjustment mode again. This arrangement adds a locking mechanism on one side of the lifting drive mechanism, so that the support platform 31 can maintain a stable state after adjusting the lifting, thereby improving the safety of the device;

[0046] Since the base area of ​​most display screens is usually fixed, the center of gravity of the device is prone to instability during the process of raising and adjusting the display body 4, which is prone to instability of the device, and is not conducive to use; the present invention adds an expansion component 2 at the bottom of the bottom cavity seat 1, and when the bottom cavity seat 1 needs to be placed on the ground more stably for work, the third motor 22 is turned on the working state, the third motor 22 drives the connecting rod 23 to rotate forward, the connecting rod 23 drives the fifth bevel gear 231 to rotate forward, the fifth bevel gear 231 drives the two groups of sixth bevel gears 251 to rotate, and then the two groups of first screw rods 25 rotate and the two groups of first screw rods 25 rotate in opposite directions, and then the two groups of moving blocks 24 move in the same direction along the first screw rod 25 horizontally. The two groups of stable seat blocks 21 move away from each other at the same time until the two groups of stable seat blocks 21 are completely extended out of the outside of the bottom cavity seat 1. The increase of the two groups of stable seat blocks 21 increases the footprint of the device base, thereby lowering the center of gravity of the device, so that the device can be placed more stably on the ground, and the display body 4 is more stable when in use. When this method is not needed, in order to avoid the two groups of stable seat blocks 21 occupying the effective area, the third motor 22 drives the connecting rod 23 to rotate in the opposite direction, and then the two groups of moving blocks 24 move closer to each other, so that the two groups of stable seat blocks 21 are completely retracted into the bottom cavity seat 1. This arrangement can improve the stability of the bottom of the device through the expansion component 2, and improve the working efficiency of the device.
