PERFORATING JIG FOR DOOR-PULL FITTING HOLE OF SLIDING DOOR

摘要

PROBLEM TO BE SOLVED: To carry out smoothly quickly perforating operation by a method wherein a door-pull fitting hole is openly provided by moving circularwise a bit while an outer peripheral surface of a disk body in a trimmer is brought in contact with an inner periphery of a shallow disk-like hollow in a jig main body. ;SOLUTION: A trimmer part 3 is composed of a trimmer main body 3A and a disk body 3B. The trimmer body 3A is composed of a motor case 3A1 having a motor built-in, and a bit 3A2 protruded from an under face of the motor case, and the bit is so constituted as to be rotated with the motor. A diameter of the disk body 3B is shorter than a diameter of a shallow disk-like hollow 2D, and longer than a diameter of a circular hole 2E. Then, the bit 3A2 is affixed onto the under face of the motor case 3A1 of the trimmer main body 3A under a state of being positioned at a center of the disk body 3B.;COPYRIGHT: (C)1997,JPO
