working principle:

When the tooling for detecting the insulation resistance value of the cable is actually used, the operator first moves one end of the positive electrode connection 11 and the negative electrode connection 12 between the first blade 24 and the second blade 26, and then uses the two sets of threaded through holes 17 and the two sets of adjusting bolts 18 to cooperate with each other. The operator manually rotates the two sets of adjusting bolts 18 clockwise and counterclockwise, and the two sets of adjusting bolts 18 respectively drive the two sets of clamping plates 19 to move synchronously. When the two sets of clamping plates 19 clamp one end of the positive electrode connection 11 and the negative electrode connection 12, the operator uses the two sets of bearings 20 to manually rotate the hand wheel 34, and the hand wheel 34 can drive the wire lever 21 to rotate synchronously.
