A pair of hairdressing scissors (2) and a positioning device (70) thereof, the pair of hairdressing scissors (2) installs at least a connectin g structure (60), the connecting structure (60) is formed a recess (61), a protrusion (62) and a through hole (611). A positioning device (70) is disposed in the through hole (611) and includes a retaining member (71), an elastic member (72) and a fixing member (73). When coupling a plurality of pairs of hairdressing scissors (2) together, the protrusion (62) of a pair of hairdressing scissors (2A) is engaged in the recess (61) of another pair of hairdressing scissors (2B). The protrusion (62) moves toward and presses the retaining member (71), so that the retaining member (71) will overcome the elastic force of the elastic member (72) and retract into the through hole (611). Wh en the protrusion (62) traverses the retaining member (71) completely, and the top end of the protrusion (62) stops against the retaining wall (311 or 411) defined between the pair of hairdressing scissors (2) and the recess (61), t he retaining member (71), under the effect of the restoring force of the elasti c member (72), will partially move out of the through hole (611) and stop against the lower end of the protrusion (62).
