装置。[Claims for Utility Model Registration] A retaining tube that is fixed to one end of a cylindrical tightening net that is inserted into a power transmission line and has a female thread on the inner periphery, a puller on one end and a puller on the other end. It has a cylindrical sleeve into which a steel core wire of a power transmission line can be inserted, a male thread on the outer periphery of the sleeve that is screwed into the female thread of the retaining cylinder, and a female thread on one end side of the inner periphery, a pull body having a tapered hole that narrows toward the other end of the inner periphery; a side wire of the steel core wire can be inserted into the tapered hole of the sleeve along the outer periphery; a wedge tube that has a tapered part that reduces in size and has a through hole in the center into which the core wire of the steel core wire can be inserted; The power transmission line extension comprises a push-in bolt that can be screwed into one end of the sleeve to push the wedge tube toward the pointed end and sandwich the side wire between the inner periphery of the tapered hole and the outer periphery of the tapered part. Connecting device for line work.
