[0027] Working principle: First, a rubber pad 14 is threadedly connected to the lower end of the support base 10. The lower end of the rubber pad 14 is fixed to the support member 9. The lower end of the support member 9 is threadedly connected to the support base 10.

When the angle is fixed, the angle adjustment mechanism 4 can also be integrated with the lead wire lead-out assembly 3. The rotating platform 7 can be of various shapes, such as circular, annular, or fan-shaped. This device uses a fan-shaped design as an example. The support base 10 can be rectangular, cylindrical, etc. Taking a rectangle as an example, the bottom of the support base 10 is fan-shaped, just like the rotating platform 7. The support member 9 and the fixing clip 8 are used to support the lead wire lead-out component 3. To ensure the stability of the lead wire lead-out component 3, the support member 9 and the fixing clip 8 must match the shape of the lead wire lead-out component 3.

The fixing clip 8 is installed together with the support base 10, usually connected by an insulated screw.

By rotating the angle adjustment mechanism 4, the lead wire lead-out component 3 can be accurately positioned to meet the needs of different installation environments. In addition, a sealing ring is provided between the rotating part and the fixed part of the angle adjustment mechanism 4 to ensure that the internal structure is not affected by moisture and dust when used in harsh environments. In terms of material selection, corrosion-resistant and high-strength alloy materials are used to ensure long-term stable operation. In practical applications, it can effectively reduce installation and maintenance time and improve the operating efficiency of power transformers.
