Abstract

An apparatus for driving a spiral coil into a document ring synchronously adjusts a winding and a longitudinal size thereof, so that a document is convenient for arranging. The apparatus includes a winding bearing set, an adjustment module, and a longitudinal cut module. The winding bearing set has a driving shaft for driving the spiral coil into the holes drilled on the document, and an auxiliary shaft for supporting the spiral coil. The longitudinal cut module is adapted to cut the spiral coil at an end thereof according to an external diameter of the spiral coil, and to synchronously bend the spiral coil to prevent the spiral coil from departing from the document. The adjustment module synchronously adjusts a distance between the auxiliary shaft and the driving shaft, and a position of the longitudinal cut module. Therefore the winding bearing set and the longitudinal cut module synchronously meet spiral coil with the same diameter. By the aforementioned design, an objective of conveniently assembling spiral coil into the holes drilled on the document is achieved.
