Claims

[Scope of utility model registration request]

In a hacksaw, the tightening bolts are inserted into holes drilled at both ends of the bow-shaped arm, and the tightening bolt side is tightened to the handle through tensioning the saw teeth through nuts and washers. A tightening bolt and a handle are inserted into holes at both ends of the arm and have a circular cross-sectional shape so that the hole insertion portion can be rotated, and the tightening bolt and the handle are formed on outer end surfaces of both ends of the arm. It is characterized by comprising a sliding means rotatably disposed, and a fixed frame into which both ends of the arm are inserted from the sawtooth side of the arm, and whose image front end is attached to and detached from the washer and the handle. A hacksaw.
