Rebar tying tool

A rebar tying tool configured to tie rebars with a wire, the rebar tying tool comprising:

• a housing;
• a feed unit comprising a feed roller configured to feed the wire toward the rebars;
• a cutter configured to cut the wire by being rotated relative to the housing;
• and
• a twisting unit comprising a holder unit configured to twist the wire cut by the cutter,
• wherein
• the cutter comprises:
• a cutting part comprising a cutting edge configured to contact and cut the wire,
• a first supporting part connected to one end of the cutting part and configured to support the one end of the cutting part such that the one end of the cutting part is rotatable relative to the housing, and
• a second supporting part connected to another end of the cutting part and configured to support the other end of the cutting part such that the other end of the cutting part is rotatable relative to the housing,
• the first supporting part and the second supporting part receive a reaction force which the cutting part receives from the wire when the cutting part cuts the wire,
• the cutter further comprises a cutting hole,
• the cutting part is configured to cut the wire inserted into the cutting whole,
• the first supporting part comprises:
• a peripheral portion directly connected to the cutting part, being spaced apart from the second supporting part, and facing the second supporting part;
• and
• a protrusion directly connected to the peripheral portion and the second supporting part, being spaced apart from the cutting part, and facing the cutting part, and
• the cutting hole constitutes a through hole surrounded by a first edge, a second edge, a third edge, and a fourth edge, which are respectively formed from the cutting part, the second supporting part, the peripheral portion and the protrusion.

• a first cutter;
• a second cutter configured to cut the wire by moving relative to the first cutter;
• and
• a twisting unit comprising a holder unit configured to twist the wire cut by the second cutter,
• wherein
• the second cutter comprises:
• a cutting part comprising a cutting edge configured to contact and cut the wire;
• a connecting part connected to the cutting part;
• and
• at least one coupling part,
• one of the cutting part and the connecting part comprises at least one receiving part recessed toward inside of the one of the cutting part and the connecting part, and
• the connecting part is connected to the cutting part by each of the at least one receiving part receiving corresponding one of the at least one coupling part.
