The invention discloses an electric razor. The electric razor is mainly used for solving the problems that a cutting device of an existing electric razor is not sharp enough during cutting, and is poor in cutting effect. The electric razor is characterized in that a motor is in driving connection with an eccentric shaft; an oscillating rod is arranged in a shell in a hinged manner, and the eccentric shaft is connected with the oscillating rod and can drive the oscillating rod to swing back and forth according to the hinged point of the oscillating rod; and a hair cutting device is movably arranged on the outer side of the shell, and is provided with a first position separated from the oscillating rod and a second position connected with the oscillating rod. The electric razor has the advantages that the motor of the electric razor directly carries out cutting actions by driving the hair cutting device through the eccentric shaft and the oscillating rod, power transmission is more direct and effective, and it is guaranteed that the hair cutting device is sharp during cutting, and is good in cutting effect.
