The utility model discloses a high-voltage equipment grounding tool and particularly relates to a grounding wire operating rod. The grounding wire operating rod comprises an operating rod (1) and a grounding clamp (2), wherein the grounding clamp (2) is connected with a grounding wire, the operating rod (1) and the grounding clamp (2) are connected with each other through a universal rotary joint (3), and the universal rotary joint (3) is mainly formed by matching a spherical inner plug (31) with an annular outer sleeve (32). The grounding wire operating rod can freely adjust the bending direction of the grounding clamp through the universal rotary joint so that the influence of an operating space is greatly reduced when a worker uses the grounding wire. The direction of the grounding clamp can be adjusted in advance directly according to the actual needs, and then the grounding clamp is directly hung and buckled on a line of tested equipment. In addition, the grounding wire operating rod has the advantages of simple structure, light weight and lower manufacturing cost.
