[0051] Referring to Figures 3 to 5The outer sleeve of the telescopic rod 404 is provided with a spring 405, when the rotating clamping plate 403 rotates, the spring 405 is compressed or stretched to store elastic potential energy; when the external force disappears, the spring 405 releases the elastic potential energy to push the rotating clamping plate 403 back to the initial position, so that the clamping rod one 406 can accurately be clamped or separated from the frame 1 and the display plate 6, and the automatic reset function of the dismounting mechanism 4 is realized, one end of the spring 405 is fixedly connected to the outside of the rotating clamping plate 403, the other end of the spring 405 is fixedly connected to the outside of the connecting block 401, the outside of the telescopic rod 404 is fixedly connected to the outside of the rotating clamping plate 403, the outside of the rotating clamping plate 403 is fixedly connected with a handle 407, when the installation or dismounting operation is needed, the operator only needs to hold the handle 407 and apply an external force, so that the rotating clamping plate 403 can be easily rotated, thereby driving the clamping rod one 406 to realize the clamping or separation with the frame 1 and the display plate 6;

[0052] Specifically, the telescopic rod 404 outside the rotating clamping plate 403 is sleeved with a spring 405, and the two ends of the spring 405 are respectively connected to the rotating clamping plate 403 and the connecting block 401. When the rotating clamping plate 403 rotates, the spring 405 is compressed or stretched to store potential energy. When the external force disappears, the spring 405 releases the potential energy to push the rotating clamping plate 403 back to the initial position, so that the clamping rod one 406 can accurately clamp or separate the frame 1 and the display plate 6, and realize automatic reset. The telescopic rod 404 is fixed outside the rotating clamping plate 403 to provide telescopic support for it. The rotating clamping plate 403 is provided with a handle 407, and the operator holds the handle 407 and applies an external force when installing or dismounting, so that the rotating clamping plate 403 can be easily rotated, thereby driving the clamping rod one 406 to complete the clamping or separation operation with the frame 1 and the display plate 6, which is convenient and fast.

The outside of the clamping rod one 406 is in contact with the outside of the frame 1, and the outside of the clamping rod one 406 is clamped with the inside of the display plate 6. The outside of the limiting clamping rod 5 is slidingly connected to the inside of the clamping rod one 406, and the outside of the connecting block 401 is fixedly connected to the outside of the connecting piece body 3 on the front and back sides;

[0054] Specifically, the adapter block 401 is first fixed on the outside of the connecting member body 3 on both sides. Then, the rotating clamping plate 403 is rotated, so that the clamping rod one 406 fixed on one end thereof is accurately clamped into the clamping slot inside the display plate 6, the clamping with the display plate 6 is completed, and the outer part of the clamping rod one 406 is in contact with the frame 1. It is worth mentioning that the limiting clamping rod 5 not only connects the frame 1, but also slides inside the clamping rod one 406. This design greatly enhances the connection stability between the clamping rod one 406 and the frame 1 and the display plate 6, ensures the stability and reliability of the entire display structure during use, and ensures the display effect through the cooperation of various components.

[0055] Working principle: regarding the magnetic attraction mechanism 7, due to the characteristics of magnetic attraction, the connection between the magnetic attraction seat 701 and the display article is realized by magnetic force. This connection mode is non-permanent. When it is necessary to adjust the position and angle of the display article, only a certain external force is needed to overcome the magnetic force between the magnetic attraction seat 701 and the display article, so that they can be separated or relatively moved. Then, the display article is placed at the required position and angle again, and is fixed by magnetic force again, so that the display effect is conveniently and quickly adjusted.

[0056] When the two frames 1 are disassembled, the clamping rod one 406 is unlocked by taking out the limiting clamping rod 5. The spring 405 outside the telescopic rod 404 is deformed by pressing the handle 407, so that the telescopic rod 404 is extruded by the rotating clamping plate 403, and the clamping rod one 406 is separated from the frame 1, so that the two frames 1 are separated. When the two frames 1 are connected, the spring 405 at the bottom of the rotating clamping plate 403 is deformed by releasing the handle 407, so that the clamping rod one 406 is clamped with the frame 1 by rotating the clamping plate 403. At this moment, the clamping rod one 406 is in the locked state by inserting the limiting clamping rod 5, so that the connection of the two frames 1 is realized.

[0057] Finally, it should be pointed out that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
