The cutting heads can't adjust their angles to the changing diameter of the face, resulting in ineffective shaving of certain facial hair areas. Furthermore, uneven pressure from the heads can cause discomfort during use.

[0003] In order to solve the above problems, the floating cutter head is now more popular, which can fit the user's facial skin 360° to achieve effective and complete cutting.

[0004] However, due to the addition of a floating structure in the cutter head, the internal structure of the cutter head is relatively complex. For example, Chinese patent application number: 201410750358.6, application date: December 10, 2014: A spherical floating razor head structure, the design of which requires the use of a large number of parts, such as a floating support plate, a main transmission mechanism, a spherical floating bracket, a spherical base, and a support shell. Although the floating support plate and the spherical floating bracket are used to achieve floating coordination, the main transmission mechanism, the spherical base, and the support shell are required to support and fix the former. The structure is complex and inconvenient to assemble, and the floating is not smooth. Utility Model Content
