[0031] In actual application, the main rod 1 can be made of high-strength insulating material to avoid electric shock of the user in the leakage detection operation.
[0032] The insulated push handle 21 is slidably installed on the main rod 1;
[0033] The insulating handle 21 refers to a handle made of insulating material. By pushing the insulating handle 21, the detection rod 22 and the supporting rod 23 are linked to control the unfolding and folding of the detection rod 22, which is similar to the umbrella rib structure of an umbrella.
[0034] One end of the detection rod 22 is hingedly connected to the insulating handle 21, and the other end is provided with a current sensor 221.
[0035] The detection rod 22 is used to carry the current sensor 221, which is a sensor that can detect current. It can detect whether the contacted measured object is electrified, the size of the current, etc. It can also be called a leakage probe.
