HELI-SERT TOOL AND HELI-SERT CORRECTION TOOL

摘要

PPROBLEM TO BE SOLVED: To provide a heli-sert tool capable of reducing costs for purchasing a heli-sert, and improving working efficiency. PSOLUTION: This heli-sert tool 10 comprises a tool shaft 11, a tongue gripping part 13, a heli-sert engagement part 14, and a handle. The heli-sert engagement part 14 has a heli-sert groove 19, and the heli-sert groove 19 is a groove, to which a cutout is formed perpendicular to an axial direction of the tool shaft 11. Because the heli-sert groove 19 can be easily hooked to a first winding 26 of a heli-sert 21 detached from a threaded part 23, so as to improve operability of the heli-sert tool. Also, there is no need of preparing a new material for forming the heli-sert groove 19, so as to realize a low price of the heli-sert tool. PCOPYRIGHT: (C)2008,JPO&INPIT
