Technical Field

[0001] The utility model relates to the technical field of shavers, in particular to a split swing head structure of a shaver. Background Art

[0002] A shaver includes a main body and a cutter head device arranged at the end of the main body. The main body is provided with a housing and an end cover detachably connected to the end of the housing. An accommodation space is formed between the housing and the end cover. An activity space communicating with the accommodation space is opened on the end cover. The existing cutter head devices include but are not limited to a double cutter head device and a triple cutter head device.

[0003] For the double cutter head device, reference can be made to a cutter head device and a shaver disclosed in Chinese Patent (Publication No. CN111438712B). The cutter head device includes a swing frame assembly and a cutter head assembly. The swing frame assembly includes a first swing frame and a second swing frame arranged in the accommodation space. The first swing frame and the second swing frame are connected to the main body and can horizontally reciprocate under the action of the driving device of the main body for realizing the shaving operation of the double cutter heads. The swing head formed on the first swing frame and the second swing frame at least partially passes through the activity space and extends outwards. The double cutter heads include a first cutter head mounted on the first swing frame and a second cutter head mounted on the second swing frame. For the triple cutter head device, the swing frame assembly includes a first swing frame, a second swing frame and a third swing frame connected between the first swing frame and the second swing frame. The cutter head assembly of the triple cutter head device includes a first cutter head, a second cutter head and a third cutter head arranged between the first cutter head and the second cutter head. The third cutter head is mounted on the third swing frame. Therefore, compared with the double cutter head device, the longitudinal distance between the swing frame assemblies of the triple cutter head device is larger. Therefore, the swing frame assembly of the triple cutter head device does not match the cutter head assembly of the double cutter head device. Similarly, the cutter head assembly of the triple cutter head device does not match the swing frame assembly of the double cutter head device. Therefore, the adaptability is poor. In addition, when the cutter head device needs to be replaced, the end cover needs to be first disassembled from the housing, and then the swing frame assembly needs to be disassembled from the main body and replaced. Therefore, the replacement of the cutter head device is very inconvenient. Summary of the Invention
