<p>PROBLEM TO BE SOLVED: To perform both wedge push-in and pull-out through the use of one wedge pushing-in device set by projecting support shafts toward both-side outsides of a clamp, fitting arms to the support shafts freely-rotatably, pressing the wedge on the anchoring side of the clamp, and pressing and extracting the wedge on the opposite side. SOLUTION: A clamp 1 grasps an electric wire opposing its clamping segments 1a, 1b having c-shaped cross sections to each other. Wedges 2a, 2b to be used are capable of filling gaps above and below an electric wire E. The electric wire E is interposed therebetween beforehand, and a belt is fastened at edge parts, and its tip part is inserted into the clamp. The clamp 1 is stuck by inserting support shafts 4 into shaft holes 3 bored in both-side central parts. The support shafts 4 protrude to the outside and lock each one end of arms 5. The support shafts 4 are on the diameter line of the electric wire E. The arms 5 are rotatable at the upper and lower surfaces of the electric wire, have holes bored at end parts, and locked to an iron tower by the holes. Consequently, a push-in device set can be diverted for a push-out purpose.</p> |
