<p>PROBLEM TO BE SOLVED: To obtain a wire grip capable of stringing an electric wire only by gripping it, and capable of grasping the electric wire firmly and surely. SOLUTION: A support frame 22 is fitted freely-slidably to each coupling end member 21 fitted to both ends of an insulation rod freely-rotatably. An operating bolt 23 is screwed into a bearing 221 being at one end of the support frame 22. At the other end of the support frame 22 and electric wire receiving part 222 is formed. Along with connecting a junction member 24 freely-rotatably at the tip of the operation bolt 23 stretching toward the electric wire receiving part 222, the junction member 24 is fitted freely-slidably to the support frame 22. To the both-wing end parts 241, 242 of the junction member 24, the intermediate part of a pair of connecting levers 25, 25 are fitted freely-rotatably. Between the junction member 24 and the electric wire receiving part 222 an electric wire pressing member 26 is connected freely-swayably to one end of each connection lever 25. Between the bearing 221 of the support frame 22 and the junction member 24, a connecting end member 21 is connected freely-rotatably to the other end of each connection lever 25. With the junction member 24 as a fulcrum, the electric wire pressing member 26, the connection end members 21, and connection levers 25 constitute a parallel movement link mechanism.</p> |
