When manufacturing (assembling) the drawn-wire temporary support tool 100 shown in FIG. 1, first, the clip 1 having the hook shape shown in FIG. 2A is prepared. For example, the clip 1 is made of iron coated with an insulating material such as plastic resin. The clip 1 is preferably provided with a handle portion 1a and a kneading portion 1b. The stagnation portion 1b has an opening width that is large enough to sandwich the armrest of the wire support. For example, it is preferable that the opening width of the rubbing portion 1b has an opening diameter that does not drop out in a state where the above-described arm metal is sandwiched. In the live-line work, the grip portion 1a is operated to open the pinching portion 1b, and the posture of the clip 1 is held by sandwiching the arm metal of the wire support.

  A clip 3 as shown in FIG. 2B is connected to one of the handle portions 1a. The clip 3 is preferably made of iron coated with an insulating material such as plastic resin in the same manner as the clip 1. Of course, it is not restricted to this, The whole may be formed with resin. As for the connection method, when both are made of iron, the ends are joined by welding. When the members are different, the end portions are joined with an adhesive. At this time, after connecting by welding, an adhesive, or the like, the joined portion may be fixed with a joining tape.

  The clip 3 is also preferably provided with a handle portion 3a and a kneading portion 3b. The stagnation portion 3b has an opening width large enough to sandwich the cap 2. Further, the stagnation part 3b is formed in a linear shape so as to be suitable for squeezing the cap 2.
