[0002] Under the background of rapid development of digital office and intelligent interaction technology, as the core output device, the portability, stability and adjustment accuracy of the adjusting assembly of the display become the focus of users. In the prior art, some patents have tried to improve the display adjustment performance by optimizing the structure, but there are still significant limitations.

[0003] For example, the Chinese patent with the authorized announcement number CN222559671U proposes a pitch adjusting assembly for display support, which adopts a double locking mechanism of damping base and pitch joint, and realizes angle fixation through threaded transmission of damping adjusting hoop. However, this scheme relies on complex mechanical structure, has large overall volume and limited adjustment range, and is difficult to meet the portable demand in mobile office scenarios. In addition, the adjustment process needs to be manually operated, lacks automatic control and precise limiting function, and the angle is easy to deviate after adjustment due to external interference, which is insufficient in stability.

[0004] Another related patent (CN222634261U) realizes angle fixation by setting a clamping column and a spring telescopic rod, which simplifies the operation steps, but the mechanical clamping mode of the clamping column and the clamping groove is easy to wear after long-term use, resulting in adjustment jamming or fixation failure. At the same time, this device only supports angle adjustment in a single direction, and cannot meet the demand of multi-dimensional view angle adjustment.

[0005] In view of the above problems, the present application provides a portable adjusting assembly for display, which solves the above technical problems. INVENTION CONTENTS
