The invention discloses a high-voltage proximity indicator and a using method thereof. The indicator comprises a base, a wire clamp mounting armour clamp, a connecting rod, a chuck and a plurality ofindicating rods. One end of the connecting rod is fixedly connected with the wire clamp mounting armour clamp and the other end of the connecting rod is hinged with the plurality of indicating rods through the base; and the plurality of indicating rods are annularly distributed around the base. The chuck is sleeved in the connecting rod; a plurality of clamping grooves are further formed in the peripheral edge of the chuck; and each clamping groove is correspondingly used for being clamped with one indicating rod in a matching manner. When the high-voltage proximity indicator is in use, the indicating rods are unfolded to indicate whether the staff member is beyond a safe operation distance or not; and when the high-voltage proximity indicator is not in use, the indicating rods are collected by the chute to reduce the occupation space of the indicator. The high-voltage proximity indicator has following advantages: whether the distance between the staff member and a live wire meets thesafety distance or not can be displayed visually; the occupation space is reduced; the own weight is reduced; the indicator is convenient to carry and transport and is used flexibly; the application range is wide; and the practicability is high.
