The mounting rod includes an insulating telescopic rod 41, a connecting base detachably arranged at the top of the telescopic rod 41, and an operating rod detachably arranged on the connecting base. The protective cover is fixed to the operating rod through a pull ear to be sent above the insulator 1. The operating rod pulls down the pull ear to move the protective cover downward and cover the porcelain cap 11, the conductive column 12 and part of the wire 2, and then passes through the two corresponding first through holes 37 and rotates at an angle to bring the two extension pieces 35 closer, and then is closed together by the closing mechanism.
