An insulating wiring device for live working

The invention relates to the field of electric power facilities, in particular to an insulating wiring device for live working. The device consists of two plates made of wood or Bakelite and hinged together, a squeeze plate is arranged after the two ends of the two plates are bent toward each other, a tong head is articulate on that inner side of the plate, and the articulate point is located at the head end of the tong head and beside the articulated point of the two plate bodies. The tong head is integrally connected with an insulating tong handle, a hollow hole is formed on the plate body,the insulating tong handle protrudes from the hollow hole, and a compression spring is arranged between the insulating tong handle and the plate body. As that plate body and the squeeze plate are arrange, the live line is firstly fixed between the two plate bodies in the construction process, and then the two joints are press together by driving the jaw heads through the two insulating jaws, so that the danger of the live
