A hanging plate 26 directly fixed to the back surface of the outer housing 1 is hung on the outer side of the fixing plate 25. A second limiting block 27 is fixedly installed at the bottom of the hanging plate 26. The hanging plate 26 is slidably connected to the outer side of the fixing plate 25. A third limiting block 28 for limiting the hanging plate 26 is protrudingly provided at the end of the fixing plate 25.

[0024] The adjusting mechanism includes: a connecting block 30 and a fixing frame 31. The fixing frame 31 is fixedly installed on the outer side of the top end of the telescopic son rod 24. The connecting block 30 is rotatably connected to the outer side of the top of the fixing frame 31. A rotating plate 29 is rotatably installed on the outer side surface of the connecting block 30. The rotating plate 29 is fixedly connected to the back surface of the fixing plate 25. A telescopic front top mechanism 32 capable of telescoping is installed at the bottom of the fixing frame 31 to support the connecting block 30. A first rotating shaft 33 is rotatably installed at the bottom of the connecting block 30. A first clamping block 34 is fixedly installed at the end of the first rotating shaft 33. The first clamping block 34 is correspondingly clamped with a first clamping groove 36 opened at the end of the rotating plate 29. Symmetrically fixed on both sides of the middle of the first rotating shaft 33 are reset springs 35. The first rotating shaft 33 abuts against the connecting block 30 through the reset springs 35. Side grooves 37 are symmetrically opened at the bottom side of the base 22. A through groove 38 opened at the side of the outer housing 1 is communicated with the side of the side groove 37. An arm 39 is rotatably installed inside the side groove 37. A ball 40 is rollingly installed on the bottom end surface of the arm 39. A second rotating shaft 42 is fixed inside the through groove 38.

A protective cloth 49 is wound around the outer side of the third rotating shaft 47.

[0025] In a specific application scenario, when in use, by lifting one side of the base 22, the support arm 39 automatically rotates under its own gravity, causing the end of the support arm 39 to rotate downward and contact the ground through the ball 40. At this time, the end of the support arm 39 disengages from the side groove 37, so that the support arm 39 does not limit the position of the limit rod 41. The limit rod 41 rotates to the surface of the support arm 39 under the elastic action of the torsion spring provided between it and the second rotating shaft 42, so as to prevent the support arm 39 from rotating back into the inside of the side groove 37, facilitating the overall movement through the rolling of the ball 40 inside the support arm 39; When it is moved to a suitable position, place the counterweight 44 on the ground.

Using the rotating structure between the connecting block 30 and the fixing frame 31, the rotation angle of the display screen can be adjusted. And through the telescoping of the front top mechanism 32, it is convenient to support and maintain the angle stability. And through the sliding structure of the hanging plate 26 outside the fixing plate 25, it is convenient to adjust the position of the display screen, so as to adjust the display for use; When storing, rotate the display screen to the outermost side of the fixing plate 25 through the hanging plate 26, limit the hanging plate 26 through the third limit block 28. By pressing the bottom of the first latch 34 by hand, the first latch 34 rotates and disengages from the first card slot 36 on the side of the rotating plate 29, so as to rotate the rotating plate 29, and thus rotate the display screen to the vertical state, facilitating the adjustment of the display. At the same time, when the display screen is vertical, through the retraction of the base 22 and the telescoping mother rod 23, the outer shell 1 is stored into the placement groove 45, so as to facilitate storage; At the same time, by pulling the cross bar at the end of the protective cloth 49 protruding outside the fixed shell 46, the protective cloth 49 can be pulled out, and the top of the protective cloth 49 is covered on the front side of the outer shell 1. The cross bar at the end of the protective cloth 49 is clamped to the inside of the third limit block 28 at the end of the fixing plate 25, so as to facilitate the limitation of the protective cloth 49, thus protecting and using. When protection is not required, through the elastic action of the return spring 48 connected between the fixed shell 46 and the third rotating shaft 47, it is convenient for the protective cloth 49 to automatically reset and wind up.
