Abstract
An electrically insulating rotary grip-all clamp stick having a double pawl operation unit for indirect hot-line work, and a method for operating an indirect hot-line tool mechanism using the clamp stick. The clamp stick is configured such that the operation unit is constituted by using a rack and a pinion gear so that a worker can safely and conveniently perform hot-line work or uninterruptible power work. A holder part and a hook assembly are operated by the operation unit, so that a tip tool can be solidly coupled to the holder part. Since a length of the operation unit is minimized, the worker can easily hold and operate the tip tool when the worker operates the tip tool, or performs work for removing a bind wire of a rotary wound-drawn type ultra-high-voltage distribution line or removing foreign substances including a layer coating an electric wire.
