The rescuer determines whether the conductor is charged by making the light emitting body 132 emit no light. If electricity exists in the rescue environment, the rescuers can take measures to carry out rescue, and therefore the safety of the rescuers is protected.

It should be noted that the precondition for the light emitting body 132 to emit light is that the electrical conductor, the rescue part 110, the light emitting body 132, the contact part 140, the human body, and the ground form a loop, so that the human body must contact the contact part 140 to form a loop, and the current in the electrified rescue environment is directed to the ground, so that the light emitting body 132 emits light by the current flowing through the light emitting body 132. Otherwise, even if the electric conductor is charged, the electric current is not conducted and the light emitting body 132 does not emit light because the human body is not in contact with the contact portion 140, thereby causing erroneous determination.

It should be further noted that the voltage of the existing commercial power supply line is 220V, and those skilled in the art should know that when a current with a voltage exceeding 36V or a current exceeding 10mA flows through a human body, the human body may be injured, in order to avoid the current in the electrical conductor from flowing through the rescue rod 100 and the human body to injure the human body, a large resistor is usually arranged inside the holding portion 130, the large resistor is electrically connected to the expansion portion 120 and the light emitting body 132 respectively, the large resistor makes the current passing through the rescue rod 100 and the human body small, usually less than 1mA, and does not injure the human body, and when such a small current passes through the light emitting body 132, the light emitting body 132 emits light to make the test result clearly displayed.

The telescopic part 120 may be a conductor to connect the rescue part 110 and the light emitting body 132, or a wire or other connection means may be provided in the telescopic part 120 to electrically connect the rescue part 110 and the light emitting body 132.

The rescue rod 100 provided by the utility model comprises a rescue part 110, an expansion part 120, a holding part 130 and a contact part 140 which are sequentially connected, wherein a luminous body 132 is arranged in the holding part 130, the rescue part 110 is sequentially electrically connected with the luminous body 132 and the contact part 140, the expansion part 120 comprises a plurality of sections of expansion rods 121 which are sequentially sleeved, and the length of each expansion rod 121 is adjustable, so that the length of the rescue rod 100 is adjustable, the length of the rescue rod 100 can be adjusted according to the situation of a site when the rescue rod is used, and the expansion rod can be used for testing whether the rescue rod is electrified in a rescue environment, so that the rescue safety is improved, and when the rescue rod is not used, the expansion rod can be contracted, and the rescue rod is convenient to carry.

Rescue portion 110 includes test head 111 and crotch 112, rescue personnel can use crotch 112 to rescue stranded personnel or object during the rescue, when the human body electrocutes, can use rescue portion 110 to promote the human body and leave electric leakage department, because test head 111 and crotch 112 have certain contained angle, can increase the area of contact of rescue portion 110 and human body, thereby make things convenient for rescue personnel to rescue, if the electric leakage power is the electric wire, can also use crotch 112 to stir the electric leakage department of electric wire and make it separate with the personnel of electrocuting. When rescue rod 100 is used for rescue, the rescuer only needs to hold grip 130.

When the rescue rod 100 is used, the test head 111 can be in contact with the conductor to test whether the conductor is electrified, when the electric wire or the conductor arranged in the air needs to be tested, the test head 111 cannot be in stable contact with the electric wire or the conductor, and in order to improve the stability of the conductor, additional measures are needed, so that the testing difficulty is increased. Hook 112 and test head 111 have a certain included angle, and the included angle can also be used to abut against the conductive body to make rescue part 110 stably contact with the conductive body.
