Description of the Related Art Regarding a power transmission line mounted on a steel tower, there is a problem that an induced current is induced in the power transmission line when the power transmission line and its accessories are inspected or electrical work is performed. Therefore, it is well known that, in general, the grounding device allows the induced current of the power transmission line to escape, and in that state the power transmission line and its accessories are inspected or electrical work is performed. Normally, on a steel tower, an insulator is used to insulate the transmission line, and an arc horn is provided on the insulator.The grounding device is what is called an earth hook. Can be engaged. Therefore, the grounding device can be engaged with the arc horn, and the induced current can be passed through the ground wire to escape to the ground.

ようにし、その安全性を高めることが要望されている。By the way, in order to ensure the safety of the worker with this grounding tool, it is necessary to prevent the grounding tool from coming off the arc horn during inspection or electrical work. Therefore, in the conventional grounding tool, a receiving metal fitting is provided on the upper end of the operating rod, an arm is attached to the receiving metal fitting, the arm is swung downward, and the arc horn is clamped between the arm and the receiving metal fitting. However, even if the arc horn is clamped between the arm and the metal fitting, this is not always the case. It is conceivable that the arc horn may come off between the arm and the metal fitting and the grounding device may come off the arc horn. If the grounding device comes off the arc horn, an induced current may cause an electric shock accident. Therefore, it is required to prevent the arc horn from coming off from between the arm and the receiving metal fitting and to enhance its safety.
