Abstract: An electric shaver includes a control unit connected to a gear set, so as to drive the gear set to rotate at least one cutter blade set for cutting beard; and a nose hair trimmer, which includes a gear mechanism, a central rotary shaft, a nose hair blade, and an engaging & disengaging element. The gear mechanism includes a gear wheel meshing with the gear set, and an engaging head connected to and rotating along with the gear wheel. The nose hair blade and the engaging & disengaging element are fixedly mounted on the central rotary shaft. When the central rotary shaft is moved forward by a predetermined distance to engage the engaging & disengaging element with the engaging head, the nose hair blade on the central rotary shaft is protruded from the electric shaver while rotating to trim nose hair.
