By protecting the surroundings, there is no concern that the metal Kikuza adapter 6 will come into electrical contact with a metal pillar or the like.

  Next, with reference to FIG. 7 or FIG. 8, the peeling method of an electric wire coating | cover is demonstrated. First, the main body frame 51 is mounted on the upper portion of the electric wire W using the first insulating operation rod 9 (see FIG. 7). Next, the electric wire W is supported from below in the vicinity of the peeling tool 5 using another set of first insulating operation rods 9 (see FIG. 7). Next, the hook portion 8a is locked in the engagement hole 53h of the gripping portion 53c, and the gripping portion 53c is rotated in one direction around the axis so that the cutting edge of the blade body 521 bites into the coating of the electric wire W.

Since the operation ring 54r is operated so as to be pushed up by the hook portion 8a, there is a problem that the operation ring 54r is easily detached from the hook portion 8a.

  Referring to FIG. 8, since the center of gravity of the peeling tool 5 is unevenly distributed toward the eye handle 53, the peeling tool 5 is moved clockwise when the eyebolt 54 exceeds 210 degrees (2 o'clock position). Since the rotating force acts, there is a problem that the operation ring 54r is easily detached from the hook portion 8a.

  Referring to FIG. 8, since the opening of the operation ring 54r penetrates in the horizontal direction, the operation ring 54r is easily detached from the hook portion 8a when the eyebolt 54 exceeds 210 degrees (2 o'clock position). There is a problem.
