The invention relates to a distribution line wire binding device which is characterized by comprising two W type wire clips (1), wherein the middles of the two W type wire clips (1) are fixed together; the two sides of the two W type wire clips (1) are bent toward opposite directions respectively; and strapping tapes (2) surround the four troughs of the two W type wire clips (1). The binding device provided by the invention changes the traditional wire binding method, the materials are simply available, and the manufacturing cost is low; a worker can quickly adapt to the binding of the wires in different specifications even without the binding training; in comparison with the traditional binding method, the device realizes firmer binding, can repeatedly use and save the wire, effectively prevents the bound wire from getting loose and dropping, avoids the hidden danger of wire burning, and lays a foundation for the safe and stable operation of the power grid line.
