FINGER-PRESSURE DEVICE FOR FINGER-PRESSING BOTH POSITIONS IN CONTACT WITH BACKBONE WITH TWO PROJECTIONS

摘要

PROBLEM TO BE SOLVED: To provide a finger-pressure device in which the distance between two projections can be adjusted to finger-press both positions in contact with a backbone with the two projections. ;SOLUTION: A body 2 is disposed on a bottom plate 1, and two projections 3 whose ends are spherical are arranged thereon. The two projections are interlocked with a rotary shaft 5 provided with right and left tread inside for every halves at the center. By rotationally operating the rotary shaft with a knob 4, the distance between the two projections can be freely moved in the opening direction and closing direction.;COPYRIGHT: (C)2000,JPO
