[0002] In daily life, when fixing various facilities and instruments on the wall or structure that cannot move or rotate, the traditional connecting method often encounters multiple challenges. Although using standard fasteners such as screws and nuts can achieve basic fixing effect, it often accompanies the following technical problems:

[0003] Limited synchronous rotation requirement of facilities and instruments: Given the fixed and non-rotating nature of the wall or structure, if the facilities and instruments themselves need to have certain rotation flexibility, the traditional connection method cannot meet this requirement. This may result in limited functionality of the facilities and instruments after installation or damage due to rotation obstruction during use.

[0004] Insufficient connection stability: Standard connectors often have difficulty providing sufficient stability and durability, especially in situations of heavy pressure or long-term use. The instability of the connection may cause the facilities and instruments to loosen or even fall off, posing a safety hazard.

[0005] Complex installation process: The traditional connection method usually requires tedious steps and precise measurements during installation to ensure the accuracy and stability of the connection. This not only increases the complexity and cost of installation, but also may delay the installation progress. CONTENT OF THE INVENTION
