As shown in fig. 1 to 7, the present embodiment provides a floating mechanism 3 for connecting between a first member and a second member to enable the first member to float relative to the second member. The floating mechanism 3 includes a floating head 200 and a mount 100, and one of the floating head 200 and the mount 100 is used for connection with a first member and the other is used for connection with a second member. The mounting seat 100 is provided with a floating groove 110, the cross section of the inner wall surface of the floating groove 110 is arranged in a polygon shape, the cross section of the outer circumferential surface of the floating head 200 is arranged in a polygon shape matched with the inner wall surface of the floating groove 110, the floating head 200 is mounted in the floating groove 110, and the outer circumferential surface of the floating head 200 is arranged in an arc shape along the direction from the groove bottom of the floating groove 110 to the notch of the floating groove 110, so that a floating gap is formed between the outer circumferential surface of the floating head 200 and the inner wall surface of the floating groove 110.

The floating mechanism 3 of the present embodiment can be applied between any two first and second members that need to float relatively, for example, the floating mechanism 3 can be applied between the cutter head assembly 1 and the cutter body assembly 2 of the shaver. One of the floating head 200 and the mounting base 100 is used for connecting with a first component, and the other is used for connecting with a second component, that is, the floating head 200 is connected with the cutter head assembly 1, and the mounting base 100 is connected with the cutter body assembly 2; it is also possible that floating head 200 is attached to blade assembly 2 and mount 100 is attached to bit assembly 1. For convenience of description, the embodiment is mainly described by taking the floating mechanism 3 applied to the shaver as an example. In the case of application to a shaver, it is preferable that the floating head 200 is connected to the cutter head assembly 1 and the mounting seat 100 is connected to the cutter body assembly 2, as shown in fig. 6 or 7, to improve the stability of the device.

The floating mechanism 3 of the embodiment can realize the relative floating of the first member and the second member, so that the connection of the first member and the second member has flexibility, thereby improving the fitting degree of the members and the surface to be contacted. For example, in the embodiment, the floating mechanism 3 is applied to a shaver, the first member is a cutter head assembly 1, the second member is a cutter body assembly 2, and since the outer peripheral surface of the floating head 200 is arranged in an arc shape along the direction from the groove bottom of the floating groove 110 to the notch of the floating groove 110, and a floating gap is formed between the outer peripheral surface of the floating head 200 and the inner wall surface of the floating groove 110, when shaving, the cutter head assembly 1 can float in a self-adaptive manner relative to the face under the matching of the floating head 200 and the floating groove 110, thereby improving the adaptability of the cutter head assembly 1 to the face.

In a form of being hinged relative to a ball head, the floating head 200 and the floating groove 110 of the floating mechanism 3 in the embodiment adopt a matching mode that the cross section is polygonal, when the cutter head assembly 1 is adapted to the face to float, the floating head 200 is not easy to rotate, the corresponding cutter head assembly 1 is not easy to rotate, the cutter head assembly 1 can be adapted to the face quickly, and the shaving efficiency is improved; and because the rotation does not take place, tool bit subassembly 1 can be under the effect of less handheld external force, hugs closely facial skin surface, has improved the skin sense when the user uses the razor, shaves cleaner.

Each arcuate face of the floating head 200 corresponds to a vertical plane of the floating slot 110, with a floating gap formed between the arcuate face and its corresponding vertical plane. The floating gap enables the floating head 200 to deflect and float at any position in the circumferential direction close to the floating groove 110, taking the position where the floating head 200 abuts against the floating groove 110 as a rotation point, that is, the floating head 200 can deflect and float within 360 degrees, so that the cutter head assembly 1 can deflect and adapt to the face under the action of external force.
