When shaving, spur this rope (1), make gear wheel (5) rotation, having driven pinion (6) also rotates, make the ball (8) that is arranged in elongate slots (62) be in the wide end place of elongate slots (62), distance between the recess inside surface A of flying wheel and the elongate slots lower surface C is greater than the diameter of ball (8), be that pinion (6) is though rotation, and flying wheel (9) does not change, flying wheel recess inside surface A is with keeping slip relatively between the pinion flange outer surface C, rotating shaft this moment (14) does not change, blade (12) does not change yet, when loosening this stay cord (1), because the recovery elastic force of spring (15), gear wheel (5) is reversed to be resetted, also driving pinion (6) reverses, make ball (8) be positioned at the narrow portion of elongate slots (62) this moment, be that the recess inside surface A of flying wheel and the distance between the elongate slots lower surface C are less than ball (8) diameter, ball (8) blocks these two faces makes pinion (6) drive flying wheel (9) reverse together, and the rotation of driven rotary axle (14) and blade (12) is shaved, when rotating speed reduces, can continue to spur this rope (1), blade has recovered rotation at a high speed again, pulling and so forth, can make blade (12) rotation more than, shave continuously.

In order to introduce conveniently, below routine embodiment do further introduction:

Fig. 1 is the profile of manual rotary micro razors

Fig. 2 is the A-A cutaway view among Fig. 1

As shown in Figure 1, the right-hand member of housing (10) is equipped with the guard that shaves (11), blade (12) is fastened on the rotating shaft (14) that is positioned on the housing (10), the blade and the guard of the common electric shaver of selling on this blade (12) and guard (11) and the market are identical, on rotating shaft (14), flying wheel (9) also securely is housed, pinion (6) is housed rotationally, the flange of pinion (61) is positioned at the recess (91) of flying wheel (9), as Fig. 2, can slide relatively between garden shape recess (91) inside surface A of the outer surface B of flange (61) and flying wheel (9), on flange (61), have the elongate slots (62) of the ball of packing into (8), the size of elongate slots (62) can make ball (8) when the left extreme position of this elongate slots (62), distance between the inside surface A of the recess (91) of flying wheel (9) and the lower surface C of elongate slots (62) is greater than the diameter of ball (8), be wide end, when extreme place, elongate slots (62) right side, the distance of A face and C face is narrow end less than the diameter of ball (8).
