The utility model provides a change uneven earthing pole of ground potential distribution for solve grounding safety nature problem. The earthing pole is helical configuration's metalwork, the earthing pole sets up the edge at the ground net, and the tip of ground net and ground net contact. The spiral height of earthing pole is 2~3m. The spiral number of piles of earthing pole is 4 layers. The apex angle of earthing pole is 40~50. Setting up of this earthing pole can effectively lower earthy skewness. And then effectively reducing touch voltage, step voltage, the security of ground net improves.
