and a movable blade 31 are attached to the lower surface of the blade base 20, and the fixing force 3 protruding from the front edge of the blade base 20 is
A skin contact surface 22 forming an angle θ of 20° to 30° with respect to the cutting edge E of the movable blade 31 is provided on the upper surface portion of the blade base 20. The spatula part 2 can be attached to the sub-holder 1 by locking the shaft part 23 formed at the rear edge to the lees receiving part 24 provided at the opening edge of the sub-holder 15.
A hook (not shown) that is rotatably attached to the blade base 20 and protrudes from the blade base 20 is attached to the sub holder.
The closed state is maintained by locking the sub-holder 15, which is attached to the opening of the sub-holder 15 and formed in two parts, to a connecting frame 25 that connects the sub-holder 15. A connecting seat 32 is fixed to the movable blade 31, with which the spherical portion 54 at the tip of the driver 5 engages. The cylindrical sub-holder 15 has an ffl mover 5 inside it.
is inserted through it, and is provided with an annular rib 17 that engages with an annular groove 16 formed on the inner peripheral surface of the cylindrical portion 14 of the holder 13, so that it can freely rotate around the pongee with respect to the circular portion &514. It is equipped with an engaging portion 19 that engages with the cylindrical portion 7 which is also attached to the cylindrical portion 14. That is, as shown in FIG. 5, one operating knob 7 is attached to one end side of the cylindrical portion 1/t so that it can rotate freely in the axial direction of the circular section 14 and does not rotate. The cylindrical part 14
A locking protrusion 71 extends from the operating knob 7 . A pair of engaging portions 19 provided on the sub-holder 15 engage with the locking projections 71, and by engaging with the locking projections 71, the rotation of the sub-holder 15 with respect to the cylindrical portion 14 is locked. . In this electric shaver configured as above,
The grip part 10 of the housing 1 and the sub-holder 15 have an angle of approximately 125° as shown by β in FIG. The grip portion 10 is substantially parallel to the grip portion 10 of the grip portion 10 . Therefore, when removing unwanted hair, when the skin contact surface 22 is applied to the skin so that the blade edge E and the skin maintain a predetermined angle, the skin and the grip part 10 are approximately parallel to each other as shown in FIG. Moreover, at this time, there is a gap between the grip part 10 and the skin where you can insert your fingers, so if you move the hand that grips the grip part 10 along the skin, the skin protector will stay in place. Electroforming work can be performed with the surface 22 in contact with the skin, that is, with the cutting edge E and the skin forming a required angle. However, if the skin contact surface 22 and the grip part 10 are made almost parallel, it is suitable for removing unwanted hair on legs and arms, but it is difficult to remove unwanted hair from the armpits. . For this reason, in this embodiment, as shown in FIG. 180° around the pongee, and the locking protrusion 71 of the operating knob 7, which returns under spring force, is engaged with the other engaging portion 19.
As shown in the figure, it is possible to hold the head part 2 in an inverted state, thereby,
As shown in FIG. 8, hair from the armpits can be easily removed. Other embodiments are shown in FIGS. 9 to 12. By connecting the sub-holder 15 and the operating knob 7 with a connecting piece 73 extending from the operating knob 7, the sub-holder 15 can be rotated by the rotation of the operating knob 7, and the direction of the head section 2 can be adjusted. It is designed so that it can be reversed,
Do not pinch or rotate the sub-holder 15 or the head section 2 (to prevent your fingers from getting hurt by the cutting edge E of the head section 2). Although the sub-holder 15 does not have a locking mechanism to prevent the rotation of the sub-holder 15 because it is moved in a direction different from the direction in which it is moved against the skin, the sub-holder 15 does not rotate inadvertently. In addition, the head part 2 in this embodiment has a detachable member 40 integrally formed at the end of the sub-holder 15 on the mounting side of the head part 2, as shown in Fig. ptS12. Slit 4 between the part connected to class 40 and other parts

To open the elastic part 42, press the detachable part 40.
It is only necessary to disengage the 7-piece 28 and the locking 7-piece 43 by bending the 7-piece 28. At this time, since the protrusion 44 pushes the rib 29 provided on the blade base 20, the blade base 20 will be opened automatically. Still other embodiments are shown in FIGS. 13 to #S19. Here, both the fixed blade 30 and the movable blade 31 in the head part 2 are double-edged types in which cutting edges E are formed on both the front and rear edges, and wind abutment surfaces 2 are provided on both the front and rear parts of the upper surface of the blade base 20, respectively.
By forming 2, both the front and rear edges of the head ¥1lls2 are electrically controlled! ). Also, although it is a double-edged type, by operating the cutting piece 35 that protrudes from the movable blade 31 and peeks out from the top surface of the blade base 20, you can slide the movable blade 31 back and forth! If the cutting edge portion of the movable blade 2 is made to protrude to either the front or rear side of the head portion 2 so that the movable blade 31 can be Since the blade tip is placed inside the head/end part 2, it prevents discomfort caused by the blade edge on the side that is not being used hitting the skin even when removing unwanted armpit hair. It has become. Further, a connecting frame 25 disposed inside the opening at the tip of the sub-holder 15 and locked by projections 48 and 49 is integrally provided with a detachable member 40, an elastic part 42, a locking hook 43, and a projection 44. . This large connecting frame 25.25, which can be attached and detached by sliding the sub-holder 151, is provided with a bracket 45 that projects into the opening where the driver 5 is located.
