The invention discloses a C-type wire clamp installation tool and a method for using the same, comprising a wire clamp clamping mechanism, a cable clamping mechanism, a wire clamp nut locking mechanism, and the wire clamp clamping mechanism including a fixed base and a movable base and the first drive part, the movable base is slidable relative to the fixed base, and is driven by the first drive part; the cable clamping mechanism includes a fixed clip, a movable clip and a second drive part, and the fixed clip is arranged on the fixed base On the seat, the movable clip can slide relative to the fixed clip, and is driven by the second driving part; the clamp nut locking mechanism includes a fixed seat, a sleeve for fitting with the clamp nut, and an insulating rod. The fixed seat is connected to Insulating rod, the sleeve is rotated and set on the fixed seat, and the insulating rod is equipped with a transmission rod. The axis of the transmission rod is perpendicular to the axis of the sleeve, and is connected to the sleeve through the transmission mechanism; An elastic piece is arranged between the fixing seats. The invention can realize the vertical installation of the C-shaped wire clip and meet the installation specification of the distribution line wire clip.
