Shaver head

Technical Field

The utility model relates to an instrument technical field that shaves especially relates to a tool bit shaves.

Background

Existing manual shavers include a shaving head (i.e., a razor cartridge) and a razor handle. Shaving heads generally comprise a shaving blade and a blade housing for mounting the shaving blade. The shaving head is rotatably mounted on the razor handle for rotational movement relative to the razor handle between a neutral position and a rotated position when the razor is in use. The razor head is detachably connected to the razor handle so that the user can replace the razor head.

In order to securely mount the razor blade to the blade housing, the conventional razor head generally uses a pair of fixing clips (generally, strip-shaped aluminum sheets) to fix both side ends of the cutting edge of the razor blade to the blade housing, and after the fixing clips are fitted to the blade housing, both leg portions (both ends) included in each of the fixing clips must be wound around the bottom surface of the blade housing. Such razor head structures are disclosed in patent documents such as razor cartridge with razor cartridge including such razor cartridge under application No. CN201480074643.9 and method of manufacturing such razor cartridge, razor cartridge under application No. CN201811539926.2 and razor under application No. CN 91103938.4.
