Moreover, the rotation angle of the universal ball 201 is limited by the first limiting part 22, the second limiting part 23 and the third limiting part 24, so that the cutter head mechanism 210 is always in a state of local micro-motion adjustable, and if the angle of the cutter head mechanism 210 needs to be adjusted by a large angle, the whole position movement of the shaver 200 can be realized by rotating the handle 220 of the shaver 200. By locally micro-adjusting the cutter head mechanism 210 of the shaver 200, the rotating assembly 20 is further kept in a balanced or stable state all the time, so that a user can scrape the beard on the abutting surface while rotating the cutter head mechanism 210.

In addition, the radian 25 of the second limiting part 23 and the third limiting part 24 is 0 to 30 degrees; when the mounting rod 230 of the bit mechanism 210 is mounted in the first mounting groove 211, the upward rotation angle of the mounting rod 230 will be limited to a range of 0 to 30 degrees, and the downward rotation angle of the mounting rod 230 will also be limited to a range of 0 to 30 degrees. Therefore, the rotation angle of the cutter mechanism 210 on the outer surface of the housing 10 will not exceed 60 degrees, and beyond the movable range of the mounting rod 230, the mounting rod 230 will be limited by the housing 10, and the rotation angle of the cutter mechanism 210 will be further limited.
