[0025] A first swing mounting groove 615 is provided on the first swing member 61. The first transmission member 71 is inserted into the first swing mounting groove 615 and is linked with the first swing member 61. A first transmission part 711 for driving the first cutter head assembly 31 and / or the second cutter head assembly 32 to reciprocate and a first limiting part 712 for limiting the first transmission member 71 in cooperation with the first swing member 61 are provided on the first transmission member 71. Such a structure can reliably limit the first transmission member, with a simple structure, so that the first swing member can reliably drive the first transmission member to act. Specifically, the specific transmission mode of the second transmission member and the second swing member can be the same as or similar to the transmission mode of the first transmission member and the first swing member, which will not be elaborated here. This makes the first transmission member have high adaptability, convenient for production and cost reduction.

[0026] The first connecting part 613 is arranged in a U shape, so that there is elasticity between the first swing part 612 and the first mounting part 611; the second connecting part 623 is arranged in a U shape, so that there is elasticity between the second swing part 622 and the second mounting part 621. Such a structure makes the first swing part and the second swing part relatively elastic, which is convenient for the eccentric member to drive reliable swinging and resetting.

[0027] There are at least two second cutter head assemblies 32. The first cutter head assemblies 31 and the second cutter head assemblies 32 are arranged alternately at intervals, and the outermost one is the first cutter head assembly 31. First elastic members 33 are provided below both the first cutter head assemblies 31 and the second cutter head assemblies 32. The first cutter head assembly can cut small beards, and the second cutter head assembly can be used to cut long beards, with better shaving effect.

[0028] The described first cutter head assembly 31 includes a first cutter head holder 311 and a first cutter net cover 313. The first cutter head member 312 is disposed within the first cutter head holder 311 and is driven by a transmission assembly 7 to swing relative to the first cutter head holder 311. The first cutter net cover 313 is disposed on the first cutter head holder 311. A second elastic member 34 is provided below the first cutter head member 312, and the first cutter head holder 311 is disposed above the first elastic member 33. In fact, the transmission assembly drives the first cutter head member and the second cutter head member to reciprocate through the first cutter head seat and the second cutter head seat respectively. Specifically, the second cutter head assembly 32 includes a second cutter head holder 321 and a second cutter head seat 322. The second cutter head holder 321 is disposed above the first elastic member 33. The second cutter head member 323 is disposed on the second cutter head seat 322 and is linked with the second cutter head seat 322. A second cutter net cover 325 is sleeved outside the second cutter head member 323. A connecting plate 324 is provided on the second cutter head holder 321. The connecting plate 324 is disposed outside the second cutter head seat 322 and / or the second cutter head member 323 for limiting the swing of the second cutter head member 323. In fact, the second cutter head member can also float, that is, an elastic member is provided between the second cutter head holder and the second cutter head seat, so that both the second cutter head member and the first cutter head member can float, and the shaving effect is better. Generally speaking, the first cutter net cover is usually more conducive to cleaning short beards, and the second cutter net cover is usually more conducive to cleaning long beards, so that the beard cleaning is more thorough and the shaving effect is good.

[0029] The present utility model further includes a trimming mechanism 8 disposed on the housing 1. The trimming mechanism 8 includes a trimming assembly 81, a limiting member 82, and a reset member 83. The trimming assembly 81 has a first position for opening for trimming and a second position for closing. The limiting member 82 limits the trimming assembly 81 when the trimming assembly 81 is in the second position. The reset member 83 is connected to the trimming assembly 81 and has a tendency to drive the trimming assembly 81 towards its first position. Specifically, the trimming assembly 81 includes a first trimming knife 811, a second trimming knife 812, and a trimming transmission member 813. The first trimming knife 811 is disposed on the trimming transmission member 813 and is driven by the trimming transmission member 813 to move relative to the second trimming knife 812. A trimming transmission portion 8131 is provided on the trimming transmission member 813. A swing driving groove 64 is provided on the swing assembly 6. The trimming transmission portion 8131 is inserted into the swing driving groove 64 when the trimming assembly 81 is in the first position and is driven by the swing assembly 6 to reciprocate. Specifically, the swing driving groove is provided on the first swing member. Such a structure enables the power source to drive the trimming assembly to act through the swing assembly, thereby driving the first trimming knife and the second trimming knife to move relative to each other for trimming the sideburn hair, so that the user can use different functions as needed, and the product has a wide adaptation range.
