The invention relates to a high voltage iron tower grounding tool, and particularly relates to a clamp specialized for a graphite grounding rope. The clamp specialized for the graphite grounding rope comprises a clamp body. The clamp specialized for the graphite grounding rope is characterized in that the clamp body is made of anti-corrosion nonmetallic material. The middle part of the clamp body is provided with a communicated connecting port. The upper surface of the internal part of the connecting port has a planar structure, and the lower surface has a slant wedge structure. The connecting port is internally provided with a fastening inserting plate which is matched with the wedge structure. The upper surface of the fastening inserting plate has the planar structure, and the lower surface has the slant wedge structure. The clamp specialized for the graphite grounding rope of the structure has the advantages of being simple in structure, convenient in construction, corrosion-resistant, pollution-free to soil, convenient to transport and economical in cost.
