The utility model relates to a ground wire integrator, especially novel lever sliding contact ground wire integrator line integrator that contacts to earth. It is formed by the lever support is partial, the integration of slide contact subtotal ground wire is partial, and wherein the lever supporting part divides and includes base, spacing support, spacing bolt, lever support and lever, partial first bottom plate, sliding contact pole, spring, second bottom plate, outer stand pipe and the interior stand pipe of including of slide contact, and integrated partial cable, angle steel, the round steel of including of ground wire puts up and the third bottom plate, spacing support and lever support respectively with base fixedly connected, lever and lever support articulatedly, first bottom plate and lever rigid coupling, the both ends of round steel frame respectively with third bottom plate and angle steel rigid coupling, the angle steel passes through the cable and is connected with the second bottom plate. It has overcome the drawback that big, the easy distortion of the volume of polishing was tied a knot and easy winding damages after the ground line weld of traditional cable formula, has produced certain beneficial effect.
