The length of the guide groove 532 is set to be equal to the swing stroke of the first swing frame 2 and the second swing frame 3 in order to prevent the first swing frame 2 and the second swing frame 3 from excessively swinging to damage the movable blade and the stationary blade of the cutter head, and the width of the guide groove 532 may be appropriately larger than the outer diameter of the guide shaft 531, which may facilitate assembly.
It is particularly pointed out that the cross-sectional views of fig. 9 and 16 of the drawings of the specification are not taken along straight lines, but are broken lines to facilitate an understanding of the application, and that some of the principal structures are presented to the examiner in a clearer manner.
The present inventors have further proposed a shaver using the above head device, as shown in fig. 17, based on the above technical solution, the shaver includes the head device according to claim 5 or 6.
The shaver adopting the two cutter head devices not only can realize the reciprocating reverse swing of the double cutter heads, but also can reduce the integral vibration intensity of the shaver on the basis of reducing the integral vibration amplitude of the shaver, improve the use comfort of the shaver and meet the product requirement of the market on low vibration intensity (low noise).
The above embodiments should not be construed as limiting the invention, but any modifications based on the spirit of the invention should be within the scope of the invention.
