From opening position be provided with the pilot hole that a diameter reduces relative to the internal diameter of hollow structure, the rear end of the body of rod that insulate is insulation hand
Portion is held, insulation pressing handle is rotationally connected with insulation Handheld Division, and the front end in the portion that is connected is U-clamp harden structure, linkage
The rear end of connecting portion is the lead coordinated with the pilot hole, and the front-end and back-end in the portion that is connected are integrally formed, linkage
The lead of connecting portion rear end can be inserted into the pilot hole up or down, be oriented to hole end surface and lead and U-clamp
Connecting end surface intermediate sleeve between harden structure is equipped with back-moving spring, and draught line one end is connected with insulation pressing handle, and draught line is another
One end is connected with the lead, and the first from left right side is rotatably connected to the insulation body of rod by bearing pin respectively for left pincers portion and right pincers portion
Front end；When pressing insulation pressing handle drives draught line that the portion of being connected can be driven to move towards left pincers portion and right pincers portion；
Conductive contact winding layer is provided with the leading portion in left pincers portion and right pincers portion, the conductive contact winding layer in left pincers portion or right pincers portion
On be connected with copper ring, the copper ring is connected with electro-detection test instrument by electric connection line.
Further, the conductive contact winding layer is located at left pincers portion or sheet copper in right pincers portion for volume or is wrapped in a left side
Copper wire wound around coil in pincers portion or right pincers portion.
Further, the electro-detection test instrument model MD-1B metal oxide arrester live detection instrument.
Further, the portion of being connected is insulation system made of insulating materials.
Its advantage is the present invention compared with prior art：Operating personnel carry out live detection using the device of the present invention
When, the security of testing crew greatly improves, can substantially pull open with the distance with high voltage equipment, avoid testing crew by high pressure
The injury of electricity.Avoid that the accident that a personnel are injured by high-tension electricity occurs, retrieve a loss in the millions；2nd, experiment work efficiency
Greatly promote, be previously required to the work in ten man-hours of testing crew, after the present invention is employed, man-hour number will reduce half, effect
Rate is doubled.
