Claims

[Scope of utility model registration request]

The rod shaft at one end of the torsion coil spring is fixed to a clamping body, and the rod shaft at the other end of the torsion coil spring is fixed to a lever and the lever is rotated to deform the torsion coil spring. In a file binding tool configured to obtain the binding force of the clipping body by using the elastic restoring force based on the deformation of the file, the support shaft around which the coil part of the torsion coil spring is wound. The coil portion of a second torsion coil spring is wound in series, the rod shaft portion at one end of the second torsion coil spring is connected to the clamping body, and the rod shaft portion at the other end is positioned inside the lever. A file binding device characterized in that the file binding tool is arranged in such a manner that it can come into contact with a lever and receive a load only when the clamping body floats a predetermined height from a substrate.
