Live-line detection auxiliary device

The live-line detection auxiliary device comprises a first sleeve and a second sleeve, the second sleeve is installed in the first sleeve and can move in the axial direction of the first sleeve, and a detection placing device is hinged to the top end of the second sleeve. The live-line detection auxiliary device has the positive effects that the ultrasonic generator for testing is mounted in the detection placement device, so that the contact area and the contact stability of the detection probe and the equipment shell can be greatly improved through the sleeve and the contact supporting legs; the angle of the detection placement device can be adjusted as required, the sleeves can be telescopically adjusted to adapt to various detection positions with different distances, accurate measurement of each detection position is achieved, additional tools such as an insulating ladder are not needed, the detection efficiency is effectively improved on the premise of ensuring the detection quality, and meanwhile, vari
