A high-strength one-touch rebar coupler includes a coupler body having a hollow portion in the longitudinal direction. The coupler body is formed in a helical shape to provide the inner peripheral surface of the hollow portion with a rebar fastening force in the circumferential direction. The coupler body includes a first guide helix coupling portion, which has first guide sloping portions that slope from the center portion of the hollow portion towards the outside of one side thereof, and a second guide helix coupling portion, which has second guide sloping portions that slope from the center portion of the hollow portion towards the outside of the other side thereof. A first fastening unit is screw-coupled to the first guide helix coupling portion and inserted into one side of the hollow portion. The first fastening unit includes first fastening members, which are slidably coupled to the first guide sloping portions.
