DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a reciprocating electric shaver according to the present invention in which a trimmer blade head and a net blade head can be selected and exchanged will be described in detail with reference to FIGS. explain. As shown in FIG. 1, the electric razor which can be replaced by selecting a head is provided with a motor 3 in a split housing 1 and a housing 2, and the motor 3 is provided with an eccentric balancer 5 having an eccentric shaft 4. ing. By turning on / off the switch 6, the battery 7 is electrically connected to the motor 3 to drive the motor 3. An eccentric balancer 5 having an eccentric shaft 4 driven by rotation of a motor 3
Rotates, and the amplitude of the eccentric shaft 4 output from the main body is determined by the mounting position of the rotating shaft center of the motor 3 and the eccentric shaft 4. The blade head is attached and detached by the detachable button 8 and the detachable spring 9. The eccentric shaft 4 shown in FIG. 4 is exposed on the main body, and is connected to the fitting portion of the blade head. The net blade head 10 which is detachable from the main body is adapted to fit and fix the outer blade block 12 to the net blade holder 11. Inner blade 1
The motor 3 has a long groove 36 shown in FIG. 3 which is detachably attached to the head of the driver 14, has an inner blade push-up spring 15 disposed therein, and presses the inner blade 13 against the outer blade 16. The reciprocating movement of the eccentric shaft 4 by the amount of eccentricity of the eccentric shaft 4 by the rotational drive of the eccentric shaft 4 transmits the drive to the inner blade 13. As shown in FIGS. 5 and 6, a long groove 18 connected to the eccentric shaft 4 is provided in the inner cutter block 17, and a push-up spring 19 is arranged in the long groove 18 so that the eccentric shaft 4 slides up and down. Attach the moving plate 20. The sliding plate 20 is provided with a long groove 21 connected to the eccentric shaft 4, fitted to the eccentric shaft 4, reciprocated by the amount of eccentricity of the eccentric shaft 4 by the rotation of the motor 3, and Drive transmission. The inner blade block 17 pushed up by the eccentric shaft 4 slides in close contact with the outer blade 16. If the inner cutter block 17 is provided with the inner cutter guide 22 to facilitate the reciprocating sliding of the outer cutter 16, the rotational movement of the eccentric shaft 4 can be converted into a reciprocating movement. A fixed blade 24 and a movable blade 25 shown in FIG. 2 are disposed on a trimmer blade head 23 that is detachable from the main body. The movable blade 25 has a long groove 27 connected to the eccentric shaft 4 on the main body side, and reciprocates by the amount of eccentricity of the eccentric shaft 4 by the rotation of the motor 3 to cut the hair. The trimmer blade block 28 can be attached to and detached from the trimmer blade holder 29. When cleaning fuzz or the like adhered between the fixed blade 24 and the movable blade 25, the trimmer blade block 28 can be attached and detached and cleaned. Convenience is improved by attaching an attachment 30 to the trimmer blade head 23 that can adjust the cutting height and adjust the plow amount. This attachment 30 can be attached to and detached from the trimmer blade head 23, and the attachment is released by pressing the lever of the attach / detach button 31 shown in FIG. 7 or 8 for attaching and detaching the trimmer blade head 23 and the main body. By doing so, you can remove it. By arranging the attachment / detachment button 31 on a surface different from the attachment / detachment button 8 for attaching / detaching the blade head, it is possible to select whether the trimmer blade head 23 and the attachment 30 are attached / detached together or only the attachment 30 is attached / detached. can do. Attachment 30 is trimmer blade head 23
If it can be attached and detached and fixed to the net blade head 10, it can also be used as protection for the blade. That is,
It can be used as an outer blade protection cap (not shown). The connection fitting 32 electrically connects the motor 3, the battery 7, and the switch 33. The fixing plate 34 fixes the driver 14 to the net blade holder 11 with screws 35.

As described above, according to the present invention, a trimmer blade head and a net blade head can be selected and exchanged in a single-step razor, and the eccentric shaft for transmitting the drive to the separable blade head is provided on the main body side. The blade head is provided with a rotary-to-reciprocating motion converting unit for converting the rotational drive of the eccentric shaft into a reciprocating motion, so that the common body block can exchange and drive the trimmer blade head and the net blade head.
