The invention relates to a distribution ground rod having a detachable operating handle and an application method thereof. The distribution ground rod comprises a ground rod body, wherein the ground rod body comprises a vertical rod segment and a hook. The distribution ground rod is characterized in that a bottom end of the vertical rod segment is provided with a rotary supporting mechanism, connection with the detachable operating handle is realized by utilizing the rotary supporting mechanism, the rotary supporting mechanism comprises a rotary shaft, supporting rings and a vertical sleeve, the bottom end of the vertical rod segment of the ground rod body is inserted into the vertical sleeve and is locked by utilizing a locking nut, a circumferential surface of the rotary shaft between the two supporting rings is fixed with a limit sleeve perpendicular to an axial line of the rotary shaft, the other end of the limit sleeve is inserted into a piston rod, a stretching spring is connected between an inner end of the piston rod and the rotary shaft, and the detachable operating handle comprises an insulation rod and a hollow pipe fixed at the front end of the insulation rod. The distribution ground rod is convenient to operate, is reliable to use, realizes time saving and labor saving during ground wire mounting and dismounting, realizes hidden safety trouble elimination and has no damage to the ground wire in the operation process.
