An insulating inner rod 21 is provided in the internal cavity of the insulating sleeve 1.

[0022] A dynamic measuring claw 72 is fixedly installed on the top of the insulating inner rod 21. The outer end of the dynamic measuring claw 72 passes through the upper slide groove 12 and can slide in the upper slide groove 12. The thickness of the fixed measuring claw 71 and the dynamic measuring claw 72 is 1-2 cm. The contact area between the fixed measuring claw 71 and the dynamic measuring claw 72 and the cable is large, which improves the measurement accuracy.
