High -voltage testing overhead line device

The utility model provides a high -voltage testing overhead line device constitutes butterfly nut (1), universal buckle (2), a clamp mouthful unlocking means (3), a clamp mouthful clamping device (4), clamp mouth (5), quick clamp (6), extendible insulating pole (7), card wire casing (8), clamping handle (9) by eight parts. The device can fix in the optional position according to site environment during the use, and the solid constant angle degree of universal buckle adjustment presss from both sides a mouthful locking device locking clamp and holds the object, and extendible insulating pole adjusts the height, presss from both sides a mouthful fixed high -voltage testing line. Realized the high -voltage testing in -process, examination article and the earth are kept away from to the high -voltage testing line, have solved the built on stilts problem lack of standardization of on -the -spot high -voltage testing line, have guaranteed operating personnel's the personal safety and the safety of examination artic
