When the warning light is on, it can prompt the staff that the puncture is successful, and the electrical tester is used to test the electrical test ring connected to the transmission line. After confirming that there is no voltage, the existing ground rod is used to hang the ground on the electrical test ring. In this way, the problem of safe electrical testing without an electrical test ring on the insulated line can be solved, which is convenient for the staff to operate. However, there are still some shortcomings in operation. When the staff is working at high altitude, they need to hold the safety position with one hand and rotate the handle with the other hand. Not only is the speed slow and inconvenient to operate, but there are also safety hazards. Summary of the invention
