Equipped with metal strip, the metal strip and starting rod rotation connection, the starting rod, which is equipped with, leaves institute for the metal strip
State the elastic component of starting rod.
Further, the clamping plate includes lower clamp plate, upper clamp plate and fixing bolt, and the lower clamp plate is fixed on the insulation
On son, the upper clamp plate is fixed on the lower clamp plate by the fixing bolt.
Further, the top of the starting rod and the metal strip junction is equipped with shield, and the shield is half
It is round.
Further, the elastic component is torque spring.
Further, the metal strip is equipped with electric discharge bulb close to the side of striking head.
Further, the metal strip and starting rod surface are equipped with insulating layer.
The utility model has the beneficial effects that: insulator lower end is equipped with fixed column, the fixed column is equipped with foundation bolt
With striking head, it is fixed on Electric wire support using foundation bolt.Insulator upper end is equipped with the clamping plate and starting rod of fixed transmission pressure,
