PIVOT STRUCTURE OF SCISSORS

摘要

In opening and closing scissors, separation between both blades caused by inclination of one blade body relative to the other blade body is prevented or reduced. Specifically, with a head being in contact with a movable blade, a coil spring comes into contact with a head at one end and with the bottom of a counterbore at the other end. This pressing force allows a stationary blade to tightly abut on the movable blade. A taper face is formed at the stationary blade side of the head to press and expand the one end of the coil spring radially outside a pivot.

主权项

1. A pivot structure of scissors, comprising:
first and second blade bodies each including a blade at one end side, and a finger ring at the other end side; and a pivot fitted in a through-hole formed in an intermediate portion of each of the first and second blade bodies to pivotably connect the first and second blade bodies together such that the finger rings move to and away from each other to open and close the blade bodies at the blades, wherein a counterbore is formed around the through-hole of one of the blade bodies, each of first and second brim-like heads is provided at an end of the pivot, a coil spring wound around the pivot is attached to the counterbore, with the first head being in contact with a peripheral edge of the through-hole of the other of the blade bodies, the coil spring comes into contact with the second head at one end and with a bottom of the counterbore at the other end, pressing force of the coil spring allows the one of the blade bodies to tightly abut on the other of the blade bodies, and a taper pressing part is formed at a blade body side of the second head to press and expand the one end of the coil spring radially outside the pivot.
