[0031] The working principle and use process of the utility model: After the utility model is installed, it works according to the above implementation method until all the working steps are completed.

[0032] This patent uses a removable lamp arm cover that only requires one screw, making disassembly and maintenance simple and quick; its large opening and unobstructed structural design makes the adjustment position closer to the opening, making it convenient to flexibly adjust the rotational resistance of the lamp arm according to actual usage needs, thereby optimizing the operating experience and reducing the possibility of misoperation; in addition, the two connection positions of the lamp arm adopt an innovative plug-in reinforcement structure, and each connection position is firmly connected by 4 fastening screws, ensuring sufficient connection strength and improving the stability of the lamp arm.

[0033] This patent has carefully designed damping rotation components at the upper and lower ends of the C-shaped arm, so that it can rotate horizontally 350 degrees around the lamp arm connection axis, meeting the precise adjustment requirements in various usage scenarios and effectively reducing misoperation. In the C-shaped arm part, the connector is made of die-casting process to ensure the stability of the structure; and the C-shaped arm itself is made of drawn aluminum to withstand a certain gravity. In order to enhance the rigidity and tensile strength of the C-shaped arm, multiple reinforcing ribs (first assembly groove, second assembly groove) are cleverly arranged on the structure, and these reinforcing ribs are cleverly used to construct a plug-in connection structure, thereby greatly improving the rigidity and stability of the connection.

[0034] In addition, the lamp arm cover adopts an insert-type structure design and can be fixed with only one fastening screw. The large opening design makes the damping rotating component very close to the lamp arm, greatly simplifying the disassembly, adjustment and maintenance process, improving the user experience, and increasing the practicality and convenience of the product.
