The driving source 31 may be a motor (e.g., a servo motor), an air cylinder, or the like, and in the present embodiment, a motor is used as the driving source. The eccentric mechanism 32 comprises an eccentric wheel 321 arranged on an output shaft of the motor and a driving piece 322 connected with the eccentric wheel 321, the driving piece 322 is connected with the moving blade swing part 33, two ends of the driving piece 322 are limited by grooves on two sides, the rotating motion of the eccentric wheel 321 is converted into reciprocating linear motion, and then the reciprocating motion of the moving blade 11 is driven. Therefore, the power unit is mainly arranged to convert eccentric rotation into reciprocating linear motion by using the eccentric wheel 321.

Specifically, the open/close control mechanism 2 includes: a knife cover 21, a support 22 and a push-button element 23.

The cutter cover 21 is provided with a rotating part 211 and a first connecting structure 212, and the shaver component 1 of the shaver is connected with the cutter cover 21; the housing 22 is provided with a rotary connecting part 221 which is matched with the rotary part 211 and supports the cutter cover 21 to rotate; the push-button element 23 is provided with a second connecting structure 231 matched with the first connecting structure 212, and the push-button element 23 is connected with the knife cover 21 and can move relative to the supporting element 22. Specifically, the push-button element 23 is linked with the knife cover 21, and the knife cover 21 can rotate relative to the push-button element. The first connecting structure 212 has concave-convex first engaging teeth, and the second connecting structure 231 has concave-convex second engaging teeth, and the first engaging teeth and the second engaging teeth are matched. The knife cover 21 has an arc shape relative to the movement track of the torque piece 23. As shown in fig. 4, in the present invention, the rotation portion 211 is a support rotation shaft formed on the knife cover 21, and the rotation connection portion 221 is a groove having an arc-shaped rotation support surface formed on the support 22. Specifically, the torque piece 23 has two connecting arms 232, and the second connecting structure 231 is a tooth row structure formed on the connecting arms 232.
