[0037] The first limiting ring 5 is fixedly connected to the circumferential surface of the other semicircular clamping piece 11 .

[0038] In a specific embodiment of the utility model, the inner shell 9 serves as the main supporting structure of the device to accommodate and protect the internal transformer line 3. The inner shell 9 is made of high-strength insulating material to ensure good electrical isolation performance under high-voltage environment. The transformer lines 3 are installed in groups of four inside the inner shell 9. These transformer lines 3 are responsible for converting the input high-voltage electricity into current of the required voltage level to ensure efficient transmission while ensuring safety. The bushing 10 is firmly connected through a heat shrink process, and the connecting rod 12 is installed in the bushing 10 for the semicircular clip. The rotation of 11 changes the curvature of the semicircular clamp 11, and realizes flexible clamping. Each semicircular clamp 11 is respectively sleeved on the circumferential surface of a connecting rod 12, and the opening and closing degree can be adjusted with the movement of the connecting rod 12. When the two semicircular clamps 11 are closed, the first limit circle 5 will overlap with the two second limit circles 13. The locking effect can be achieved by inserting the pin into the first limit circle 5 and the two second limit circles 13. When installing the high-voltage line, it can be accurately positioned and kept stable, ensuring the stability of the connection and electrical safety, and being more firm and not falling off.
