The application provides two kinds of transmission structures of first pendulum frame and second pendulum frame
Example 1
As shown in fig. 2 to 9, in order to facilitate the first swing frame 2 to swing horizontally and reciprocally under the driving of the driving member, the second swing frame 3 can swing synchronously and reversely with the first swing frame 2, and the kinetic energy inertia generated by the swing is buffered by the movement of the two swing frames in opposite directions, so as to reduce the amplitude and the vibration intensity of the cutter head. The transmission part 5 comprises two first linkage parts 51, the two first linkage parts 51 are arranged and are respectively arranged at two ends of the first swing frame 2 and the second swing frame 3, when the first swing frame 2 is driven by the driving part to horizontally swing back and forth, the second swing frame 3 can synchronously move reversely under the driving of the two first linkage parts 51, and in the process of reverse swing movement, the limitation of the two first linkage parts 51 can be realized, the parallel and spaced arrangement of the second swing frame 3 and the first swing frame 2 can be absolutely ensured, the resistance generated by friction between the first swing frame 2 and the second swing frame 3 can be effectively avoided, the shaving efficiency of the cutter head is influenced, the temperature rise of the cutter head is improved, the amplitude of the cutter head is reduced, and the use comfort of the cutter head is improved.

Because the first linking grooves 514 are respectively arranged at two ends of the first swing frame 2 and the second swing frame 3, when the first transmission shaft 513 is respectively inserted into the first linking grooves 514, and the driving component drives the first swing frame 2 to horizontally reciprocate, the first transmission shaft 513 in the first linking groove 514 in the second swing frame 3 drives the second swing frame 3 to reversely run under the limitation of the width of the first linking groove 514 and the action of the first hinge shaft 511, and the limitation of the length of the first linking groove 514 can restrict the swing stroke distance of the first swing frame 2 and the second swing frame 3, thereby ensuring the use safety of the cutter head. Of course, there are many structures for realizing the reverse swing of the double cutter head, and the same purpose can be achieved without adopting the transmission member 5, such as a gear and rack structure, but since the internal space of the housing 1 is limited, the gear and rack structure is not favorable for production and assembly, and therefore, the embodiment of the present embodiment is a preferred embodiment.

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, so that the movable blade and the fixed blade of the cutter head are prevented from being damaged due to excessive swing of the first swing frame 2 and the second swing frame 3, the width of the guide groove 532 can be properly larger than the outer diameter of the guide shaft 531, and the assembly is facilitated.
It is specifically noted that the cross-sectional views of fig. 9 and 16 in the drawings of the specification are not taken along straight lines, but rather are broken line cross-sectional views to facilitate the understanding of the present application, and some of the main structures are presented to the examiner in a clearer manner.
The inventor also proposes a shaver using the cutter head device on the basis of the above technical solutions of the cutter head device, as shown in fig. 17, the shaver includes the cutter head device according to claim 5 or 6.
The shaver of two kinds of tool bit devices above adopting not only can realize the reciprocal reverse swing of double-tool bit, reduces the basis of the whole amplitude of shaver, can also alleviate the whole vibration intensity of shaver, promotes the use comfort level of shaver, satisfies the product demand of market to low vibration intensity (low noise).
The above examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of protection of the present invention.
