Rapid line inspector with LEDs (light-emitting diodes)

The utility model discloses a rapid line inspector with LEDs (light-emitting diodes), comprising two LEDs A and B, a direct current power supply, an extension guide line, a positive touch probe and a negative touch probe, wherein the anode of the direct current power supply is directly connected in series with the LED A or is connected with the LED A after being connected with the extension guide line, and the other end of the LED A is connected with the positive touch probe; the cathode of the direct current power supply is directly and reversely connected with the LED B or is connected with the LED B after being connected with the extension guide line, and the other end of the LED B is connected with the negative touch probe; and the LED A and the LED B are respectively arranged at the positive touch probe end and the negative touch probe end. For the rapid line inspector, the circuit is simple, the cost is low, the connection of a line to be inspected is right or not can be judged according to the light emitting states of the LED held by a person, the result can be informed to an opposite side without shouting and an interphone, therefore, the operation is simple, and the line inspection is fast and the energy saving is realized. If the distance between the tow touch probes is not enough, the extension line only needs to be connected.
