A movable plate 19 is movably connected to one end of the first threaded rod 17. Two push plates 21 are symmetrically installed on the outer wall of the movable plate 19. A turntable 8 is rotatably installed on the outer wall of the control board 5. Two fixed grooves 9 are symmetrically opened on the outer wall of the turntable 8. A rotating shaft 6 is fixedly installed on the outer wall of the turntable 8. One end of the rotating shaft 6 passes through the control board 5 and is equipped with a display 4.

[0024] The overall effect of Embodiment 1 is as follows: when hanging upside down, the operator rotates the handle 18, which drives the first threaded rod 17 to rotate, causing the moving plate 19 to move. The inclined surfaces of the two push plates 21 contact the inner walls of the two moving frames 14 respectively, thereby pushing the moving frames 14 to move. The first spring 11 is compressed. At this time, the moving frame 14 drives the placement seat 12 to leave the fixing groove 9. The operator rotates the display 4, and the rotating shaft 6 and the turntable 8 rotate. At this time, the operator rotates the handle 18 in the opposite direction, and the push plates 21 no longer contact the inner walls of the moving frames 14. The elastic force of the first spring 11 pushes the roller 13 to contact the outer wall of the turntable 8 and rolls along the outer wall of the turntable 8 until the placement seat 12 enters the fixing groove 9, thus completing the fixing and improving the scope of use.

[0025] Example 2, as Figures 1-5 As shown, the control panel 5 is further provided with an adjustment seat 3 at the bottom, an adjustment groove 22 is provided at the top of the adjustment seat 3, a storage groove 26 is provided inside the adjustment seat 3, a lifting plate 23 is slidably installed inside the adjustment groove 22, a threaded groove 24 is provided at the bottom of the lifting plate 23, a second threaded rod 25 is threadedly connected inside the threaded groove 24, and the bottom of the second threaded rod 25 enters the storage groove 26 and is fixedly installed with a worm gear 27.

[0026] Furthermore, a worm gear 28 is rotatably installed inside the storage slot 26, and a worm wheel 27 is meshed with the worm gear 28. One end of the worm gear 28 passes through the adjusting seat 3 and is fixedly installed with a handle 29.

[0027] Furthermore, an installation plate 1 is fixedly installed at the bottom of the adjustment seat 3. The four corners of the installation plate 1 are provided with installation holes 2 for mounting the device in the installation position by bolts.

[0028] Furthermore, a plug plate 36 is fixedly installed on the outer wall of the monitor 4, and a slot 37 is provided at the bottom of the plug plate 36.

[0029] Furthermore, a connecting plate 7 is fixedly installed at one end of the rotating shaft 6. A slot 30 is opened on the outer wall of the connecting plate 7. A limiting groove 31 is opened inside the connecting plate 7. A second spring 32 is fixedly installed on the inner wall of the limiting groove 31. A limiting plate 33 is fixedly installed at one end of the second spring 32. A pressure plate 34 and a locking block 35 are fixedly installed on the top of the limiting plate 33. The top of the pressure plate 34 penetrates through the connecting plate 7, and the top of the locking block 35 enters the slot 30.

[0030] Furthermore, a limiting rod 20 is fixedly installed on the outer wall of the movable plate 19. One end of the limiting rod 20 is slidably inserted into the storage plate 15 to prevent the movable plate 19 from rotating when the first threaded rod 17 rotates.

[0031] The effect achieved by the entire embodiment 2 is that when adjusting the height, the operator turns the handle 29, which drives the worm 28 to rotate. Since the worm 28 is meshed with the worm wheel 27, the worm wheel 27 rotates, which drives the second threaded rod 25 to rotate. At this time, the lifting plate 23 rises along the adjustment groove 22, pushing the control plate 5 and the display 4 to rise. In this way, the height of the display 4 can be adjusted, further improving the range of use.

[0032] Working principle: When hanging upside down, the operator rotates the handle 18, which drives the first threaded rod 17 to rotate, causing the moving plate 19 to move. The inclined surfaces of the two push plates 21 contact the inner walls of the two moving frames 14 respectively, thereby pushing the moving frames 14 to move. The first spring 11 is compressed. At this time, the moving frame 14 drives the placement seat 12 to leave the fixing groove 9. The operator rotates the display 4, and the rotating shaft 6 and the turntable 8 rotate. At this time, the operator rotates the handle 18 in the opposite direction, and the push plates 21 no longer contact the inner walls of the moving frames 14. The elastic force of the first spring 11 pushes the roller 13 to contact the outer wall of the turntable 8 and rolls along the outer wall of the turntable 8 until the placement seat 12 enters the fixing groove 9, thus completing the fixing and improving the range of use. When adjusting the height, the operator turns handle 29, which drives the worm gear 28 to rotate. Since the worm gear 28 is engaged with the worm wheel 27, the worm wheel 27 rotates, driving the second threaded rod 25 to rotate. At this time, the lifting plate 23 rises along the adjusting groove 22, pushing the control plate 5 and the display 4 to rise, thus adjusting the height of the display 4 and further improving its usability. When the display 4 needs maintenance, the operator presses down the pressure plate 34. The pressure plate 34, through the limiting plate 33, drives the locking block 35 to leave the locking groove 37, thus allowing the insertion plate 36 to be pulled out for maintenance of the display 4.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
