The invention relates to the technical field of shavers, in particular to a shaver head mechanism adopting a floating shaver rest seat structure. According to the shaver head mechanism, each floating shaver rest seat of the shaver head mechanism is made of a hard rubber material arranged in the interior and a soft rubber material covered on the exterior and forms a nail shape, wherein the outer side of the floating shaver rest seat is of an arc shape, and the inner side is a linear plain end or an intersection angle of 120 degrees; two or three floating shaver rest seats are connected by the linear plain ends or the intersection angles of 120 degrees through long strip-shaped thin soft rubber layers; and the thickness of the long strip-shaped thin soft rubber layers is 0.05mm to 0.15mm. According to the shaver head mechanism, the floating shaver rest seats are of a flexible elastic integral structure, and when the floating shaver rest seats are contacted with skin, skin contact pressure can be more uniformly distributed on various components of the floating shaver rest seats by the elasticity of the material so as to improve the comfortable sensation during shaving; and meanwhile, the front sides of the floating shaver rest seats are not provided with grooves, so that the floating shaver rest seats are easily cleaned, and potential safety hazards cannot be generated due to difficult cleaning of the grooves in the prior art.
