The invention discloses a steerable grounding device which is used for solving the problem that the angle between a grounding wire clamp and a grounding rod cannot be adjusted in the prior art, so a grounding wire is prone to fall, and safety accidents are easily caused. The grounding device comprises a grounding wire clamp and an insulating rod, the grounding wire clamp is a double-tongue wire clamp, one end of the grounding wire clamp is sequentially connected with a first direction connecting part and a second direction connecting part, one side of the first direction connecting part is provided with a first end-toothed disc, a plane where the first end-toothed disc is located is parallel to a plane where the grounding wire clamp is located, one side of the second direction connecting part is provided with a second end-toothed disc, and a plane where the second end-toothed disc is located is perpendicular to the plane wherein the first end-toothed disc is located. A third end-toothed disc is arranged at a top end of the insulating rod, a plane where the third end-toothed disc is located is perpendicular to an end face of the insulating rod, and the third end-toothed disc can bebuckled and fastened with the first end-toothed disc and the second end-toothed disc. The device has the advantages that a rotating part is added, the operation time can be shortened, and the safety and reliability of the operation can be ensured.
