TOOL FOR ATTACHING/DETACHING NUT FASTENER

摘要

PROBLEM TO BE SOLVED: To provide a tool for attaching/detaching a nut fastener that is mounted on a tip tool attached to a holding part of insulation pincers or a shared operation rod for use and can be used for attaching and detaching a nut fastener externally fitted to a screw part of a bolt screwed to a steel crossarm.SOLUTION: A tool 1 for attaching/detaching a nut fastener comprises an insertion member 2 and a reception member 3. The insertion member 2 has a tip part 25 to be inserted between a nut 102 and a nut fastener 103 and has a plate part 22 in which a recess 23 is formed whose inside width is larger than a screw part of a bolt 101 and smaller than the nut 102. The reception member 3 has a plate part 32 in which a recess 33 is formed whose inside width is larger than a tubular body 103a of the nut fastener 103 and smaller than an expanding part 103b thereof. The insertion member 2 and the reception member 3 are used in combination so that a space larger than the thickness of the expanding part 103b can be formed between a lower face of the plate part 22 and an upper face of the plate part 32.
