Claims

[Scope of Claim for Utility Model Registration] A band winding shaft for winding the other end of the band is rotatably inserted and held in the opposite side plate of the main body frame, which has a substantially U-shaped cross section and which hooks one end of the band. At the same time, an opposite side plate of an operating frame having a substantially U-shaped cross section for rotating the band winding shaft is inserted and held through the winding shaft so as to be rotatable in a reciprocating manner, and one side plate of the operating frame and the main body frame adjacent thereto By interposing a ratchet plate between the side plate and one side plate, the ratchet plate is engaged with the respective side plates in a concave and convex manner and rotates together with the winding shaft, so that the winding shaft can be rotated by reciprocating rotation of the operating frame. In a band tightening tool configured to rotate only in a predetermined winding direction and prevent rotation in the opposite direction, a plurality of notched recesses are formed in the peripheral edge of the ratchet plate, and a plurality of notched recesses are formed in the recessed parts. A protrusion that engages only when the operating frame is rotated in the winding direction is formed on the side plate of the operating frame, and a protrusion that prevents the winding shaft from rotating in the opposite direction to the winding direction is formed on the ratchet plate. A band fastener characterized in that a plurality of small holes that engage with the protrusions are formed in the side plate of the main body frame.
