[0008] As a preferred solution, the clamping bracket adopts an arc-shaped structure design, the clamping bracket is clamped on both sides of the lightning arrester, and an insulating rubber pad is provided on the inner side of the clamping bracket.

[0009] As a preferred solution, the retractable clamping rod adopts a telescopic sleeve rod and a clamping rod that limit each other's telescopic structure design, a limit adjustment screw is provided between the telescopic sleeve rod and the clamping rod, and the clamping support is adjusted up and down in height through the retractable clamping rod.

[0010] As a preferred solution, one end of the adjusting screw rod passes through the fixed mounting plate and is connected to an adjusting knob, and the clamping bracket moves horizontally by rotating the adjusting screw rod through the adjusting knob.

[0011] As a preferred solution, the two side ends of the clamping tray are provided with clamping ears, the clamping ears are provided with clamping rods and clamping grooves, and the clamping trays are clamped to each other through the clamping rods and the clamping grooves.

[0012] As a preferred solution, the support base is driven by a hydraulic lifting rod to move up and down.
