Title: Wrench for locking ring nut
Inventor: YAMASHITA HISASHI
IPC: B25B13/04
Filed: 1993-11-17
Abstract: PURPOSE:To facilitate fastening and loosening of a ring nut by providing a stepped part, which prevents further fitting when the ring nut gears with a wrench head by the depth corresponding to the thickness of the ring nut, and a through hole for passing a bolt shaft through it in a wrench head. CONSTITUTION:In a wrench, in which a gear part, of a ring nut gears with a wrench head 1, a stepped part, 12a and a through hole 13a are arranged in the wrench head 1, and the stepped part, 12a prevents the ring nut from gearing with the wrench head 1 further than the depth corresponding to the thickness of the ring nut, while a bolt shaft is passed through the through hole 13a. In this way, a gearing slip between the wrench 1 and the ring nut can be prevented by the existence of the stepped part 12a. As the bolt penetrates the through hole 13a of the wrench head 1, even a long bolt can be fastened in the ring nut, so that it is applicable to change of locking ring nuts in a steel tower in which long bolts are used.
