The invention relates to a reciprocating shaver. The reciprocating shaver comprises a shaver holder, at least two shaver heads and a driver, wherein the shaver holder comprises a shaver rack and shaver nets, each shaver head comprises a movable shaver holder and a movable blade, the driver comprises a motor and a transmission part, particularly, the shaver rack is provided with at least one shaver groove extending in the length direction of the shaver rack, the shaver nets correspond to the shaver grooves in a one-to-one mode, the number of the shaver heads is at least two, the shaver heads are divided into two groups, one or two shaver heads are arranged in each shaver groove, the two group of shaver heads are arranged in a spaced mode, the movable shaver holders of each group of shaver heads are integrally arranged and form sliding bases, the two sliding bases are arranged in a staggered or spaced mode, an output shaft of the motor is in synchronous transmission connection with the two sliding bases through the transmission part, and under the driving of the motor, the two groups of shaver heads synchronously move in opposite directions. Under the same power output, synchronous and opposite movement of the shaver heads in the shaver grooves is achieved, vibration generated when the shaver heads swing is counteracted, and therefore the vibration amplitude is reduced, and noise generated by vibration is also reduced.
