One end of stay cord is fixed on the slide block of movable clamp, and the other end is walked around after pulley the slide block below through movable clamp, and, through through hole and the insulation Nei Gan center of Connection Block, is fixed on the inwall of the outer bar of insulation;

Binding clip forms by two wire clamp monomers are hinged, and the outside of each wire clamp monomer is equipped with the bail matched with the draw-in groove of fixing chuck plate and movable clamp.

Further, the body of rod of the outer bar of described insulation is the dismantled and assembled structure of more piece or the multi-joint telescoping body of rod.

The utility model has the advantages that: simple in structure, easy to use, the inside and outside body of rod adopts high-strength insulating material to make, adopt the body of rod and binding clip separate design, solve the experiment of prior art mesohigh circuit breaker characteristic and needed several staff's compounding practices, and the problems such as testing tool is many, reduced tester's working strength, improved work efficiency.

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

The A-A that Fig. 2 is Fig. 1 is to cut-open view;
