[0095] Regarding the installation of the ball bearing 2, multiple exposure openings 15 can be provided on the outer blade holder 7a for the ball bearing 2 to protrude from the skin contact surface 11. The ball bearing 2 is larger than the exposure opening 15 and prevents the ball bearing 2 from coming out of the exposure opening 15. The bottom of the outer blade holder 7a is provided with a limiting structure that limits the ball bearing 2 to the position of the exposure opening 15.

[0096] Furthermore, the outer tool holder 7a is provided with a ball groove, and the ball is installed in the ball groove; the limiting structure can be a support plate fixed on the outer tool holder to support the ball from below. Of course, multiple balls can also be installed on a strip-shaped connecting frame and then the connecting frame is installed on the outer tool holder.

[0097] Preferably, the height h of the rolling body protruding the skin contact surface 11 satisfies 0.05mm≤h≤0.7r≤1mm, wherein, when the rolling balls 2 are provided on the outer blade 1a, the height h of the rolling balls 2 protruding the skin contact surface 11 of the outer blade 1a is preferably ≤0.5mm; the effects are that one can avoid the rolling body protruding too high to affect the stability of the rolling body assembly, and avoid the skin being lifted too high to make the skin contact surface 11 in the shaving area 12 not in good contact with the skin to reduce the shaving efficiency and the shaving closeness, and the rolling body protruding too high will also affect the skin feel; another is to avoid the rolling body being too large and the rolling body protruding too low to be difficult to drive the rolling body to roll by the skin contact friction.
