[0038] Embodiment 1:

[0039] Please refer to Figure 1-Figure 7 A display device, comprising: a device base 1, a lower display assembly 4 is arranged at the upper end of the device base 1, an upper display assembly 3 is arranged inside the lower display assembly 4, a handle bar 2 is arranged at one end of the device base 1, wheels 6 are fixedly connected at the four end corners of the lower end of the device base 1, and a battery 5 is fixedly connected at the lower end of the device base 1;

[0040] The lower display component 4 includes a lower display plate 9 and a lower display light board 28. A driving motor 13 is fixedly connected to the middle position of the device base 1. The output end of the driving motor 13 is fixedly connected to the display base plate 27. The upper end of the display base plate 27 is fixedly connected to the lower display plate 9. The display base plate 27 is located on the inner side of the lower display plate 9 and is fixedly connected to the lower display light board 28. The upper display component 3 includes an upper display plate 10 and an upper display light board 11. A telescopic rod 12 is fixedly connected to the middle position of the upper end of the display base plate 27. The output end of the telescopic rod 12 is fixedly connected to the upper plate 8. The lower end of the upper plate 8 is fixedly connected to the upper display plate 10 and the upper display light board 11. The upper display light board 11 is located on the inner side of the upper display plate 10. A limited clamping component 7 is arranged around the upper plate 8 and around the upper end of the lower display plate 9. Specifically, the driving motor 13 drives the display bottom plate 27 to rotate, thereby driving the entire device above the display bottom plate 27 to rotate, and the extension of the telescopic rod 12 drives the upper plate 8 to move upward, thereby extending the upper display plate 10 for display, and when transporting, the telescopic rod 12 is retracted to drive the upper plate 8 to enter the lower display plate 9 to reduce the volume and facilitate transportation. The design of the upper display light board 11 and the lower display light board 28 can also facilitate the lighting of the display outdoors at night.

[0041] Furthermore, the limit clamping assembly 7 includes a clamping connecting frame 14, which is fixedly connected to the lower display plate 9 at the upper part of the clamping connecting frame 14 near the lower display plate 9, and a slot is provided between the lower part of the clamping connecting frame 14 near the lower display plate 9 and the lower display plate 9, and a connecting shaft 16 is fixedly connected inside the clamping connecting frame 14, and a clamping rotating cap 15 is rotatably connected to the connecting shaft 16, and a clamping friction pad 17 is fixedly connected to one side of the clamping rotating cap 15, and the clamping friction pad 17 extends away from the side of the clamping rotating cap 15 to the outside of the clamping connecting frame 14 and fits with the lower display plate 9, and a buckling block 19 is laterally fixedly connected to the lower end of the clamping rotating cap 15, and a card slot is opened on the buckling block 19, and a buckling strip 20 is fixedly connected to the position of the clamping rotating cap 15 corresponding to the card slot, and the buckling strip 20 is card-connected to the card slot. Specifically, when it is necessary to clamp the displayed document or drawing, the clamping rotating cap 15 is first rotated to separate the buckling block 19 from the buckling strip 20. The upper end of the document or drawing is inserted between the clamping friction pad 17 and the lower display plate 9, and then the clamping rotating cap 15 is rotated to buckle the buckling block 19 with the buckling strip 20 to limit the clamping rotating cap 15, so that the clamping friction pad 17 can clamp and fix the document with the lower display plate 9.

[0042] Furthermore, a buckle groove is provided inside the clamping and rotating cap 15. Specifically, the buckle groove serves to facilitate the rotation of the clamping and rotating cap 15 and reduce the weight.

[0043] Embodiment 2:

[0044] The display device provided in Example 1 is further optimized. Specifically, Figure 7-Figure 9 As shown, further, one end of the device base 1 is fixedly connected with a fixed rotating shaft 18, and the device base 1 is rotatably connected with the handle bar 2 through the fixed rotating shaft 18, and a multifunctional handle is provided at one end of the handle bar 2 away from the fixed rotating shaft 18. Specifically, the multifunctional handle can not only be used to drag the device, but also can play a certain limiting effect on the device when it is put down outdoors and in contact with the ground, so as to prevent the device from slipping due to terrain reasons.

[0045] Furthermore, the multifunctional handle includes a hidden grounding slider 22, a sliding groove 26 is provided at the lower end of the handle bar 2, the hidden grounding slider 22 is slidably connected in the sliding groove 26, a telescopic spring 25 is fixedly connected between the hidden grounding slider 22 and the sliding groove 26, and inclined blocks 24 are fixedly connected to both sides of the lower end of the hidden grounding slider 22, and a plurality of grounding pins 23 are vertically arranged at the position between the two inclined blocks 24 at the lower end of the hidden grounding slider 22. Specifically, the hidden grounding slider 22 can slide up and down under the action of external force in the sliding groove 26, and the grounding pin 23 at the lower end of the hidden grounding slider 22 is used to increase the friction with the ground when it is deep in the sliding groove 26, and the end of the inclined block 24 close to the driving motor 13 is an inclined surface, which facilitates the driving motor 13 to slide to the outside of the hidden grounding slider 22 and press the hidden grounding slider 22 into the sliding groove 26.

[0046] Furthermore, the multifunctional handle also includes a driving motor 13, which is sleeved on the handle bar 2, and the driving motor 13 is slidably connected to the handle bar 2. The handle bar 2 is fixedly connected to a limiting thread 21 on one side corresponding to the hidden grounding slider 22, and corresponding threads are provided at both ends of the inner side of the driving motor 13. The driving motor 13 is sleeved on the outer side of the hidden grounding slider 22. Specifically, when the handle bar 2 is required to limit the device, the driving motor 13 is rotated to contact the threaded connection between the right end of the driving motor 13 and the limiting thread 21, and then the driving motor 13 is moved to the right until the thread on the left side of the driving motor 13 contacts the limiting thread 21, at which time the hidden grounding slider 22 extends out of the sliding groove 26, and then the thread on the left side of the driving motor 13 is rotated to contact the limiting thread 21, so that the driving motor 13 will be limited to the right side of the limiting thread 21. When the device needs to be towed, the driving motor 13 only needs to be rotated to the left to release the threaded connection and then connected.

[0047] When in use, place the device in a suitable position, put down the handle bar 2, and then turn the drive motor 13 to the right until the left thread inside the drive motor 13 is threadedly disconnected from the limit thread 21, and then start the telescopic rod 12 to push the upper plate 8 upward to display the upper display plate 10, so that the content to be displayed can be placed on the lower display plate 9 and the upper display plate 10. If there are documents or drawings to be displayed, the clamping rotating cap 15 can be rotated to separate the buckling block 19 from the buckling strip 20. Insert the upper end of the document or drawing between the clamping friction pad 17 and the lower display plate 9, and then rotate the clamping rotating cap 15 to make the buckling block 19 and the buckling strip 20 buckle to achieve the limit of the clamping rotating cap 15, so that the clamping friction pad 17 can clamp and fix the document with the lower display plate 9, and when it is night or when there is insufficient light, the upper display light board 11 and the lower display light board 28 can be turned on for lighting.

[0048] The above-mentioned electrical components are all electrically connected to the main controller and the power supply, wherein the main controller can be a conventional known device such as a computer for control, and the existing public power connection technology will not be described in detail here.
