Staggered multilayer trimming head applied in an electric haircutter

Abstract

A staggered multilayer trimming head installed at a front end of an electric haircutter includes a bottom plate, a fixed blade, a moving knife module and a moving swing block. The moving knife module has a first moving knife and at least one second moving knife; an adjusting lever is coupled to the second moving knife for adjusting the position of the second moving knife with respect to the first moving knife quickly, and the moving knife module is coupled to a motor of the electric haircutter with power connection through the moving swing block. In a cutting/shearing operation, the adjustable moving blade allows the cutting and shearing to be adjusted to a single cutting and shearing track or a multiple of tracks, so as to complete various haircutting effects quickly without changing the operator's original operating habit and improve the haircutting efficiency and quality significantly.

(9) With reference to FIGS. 1, 2 and 3 for the exploded view and cross-sectional view and the schematic view of a preferred embodiment of the present disclosure being installed to a main body, a staggered multilayer trimming head 2 is applied to an electric haircutter 1, wherein the electric haircutter 1 has a main body 11, a motor 12 and a power source 13 installed in the main body 11, an eccentric block 121 coupled to a front end of a rotating shaft of the motor 12 for producing an eccentric rotary motion, and the staggered multilayer trimming head 2 comprises a bottom plate 21, a fixed blade 22, a moving knife module 23, and a moving swing block 24.

(10) Wherein, the bottom plate 21 is installed and fixed to a front end of the main body 11, and three windows 211 are formed on a surface of bottom plate 21 and arranged with a space from each other. It is noteworthy that a side of the bottom plate 21 has a plurality of fixing parts 212 corresponding to the fixed blade 22 and the moving knife module 23 for installing and positioning the fixed blade 22 and the moving knife module 23.

(11) The fixed blade 22 is fixed onto the bottom plate 21 through the plurality of fixing parts 212, and a first serrated structure 221 is equidistantly disposed at a front edge of the fixed blade 22.

(12) The moving knife module 23 is movably installed on a side of the fixed blade 22, and the moving knife module 23 comprises a first moving knife 231, three second moving knives 232, three adjusting levers 233, a spring pressing plate 234 and a pressing plate 235, and the first moving knife 231 has a second serrated structure 2311 disposed at a front edge thereof and configured to be corresponsive to the first serrated structure 221, and three first notches 2312 comes with a quantity corresponding to the quantity of the second moving knives 232, and each second moving knife 232 has a third serrated structure 2321 disposed at a front edge thereof and configured to be corresponsive to the first serrated structure 221, and each second moving knife 232 is movably received in each first notch 2312, so that after the second serrated structure 2311 and the third serrated structure 2321 are combined, they are staggered with respect to the first serrated structure 221, and the rear end of each second moving knife 232 is coupled to each adjusting lever 233, so that the rear end of each adjusting lever 233 is disposed in each respective window 211 which is exposed from the bottom plate 21, and the spring pressing plate 234 and the pressing plate 235 are provided for pressing and positioning the first moving knife 231 and each second moving knife 232 on a position of the fixed blade 22. It is noteworthy that a hook 2322 is formed at a rear end of each second moving knife 232, and a first fixed portion 2331 is disposed at a front end of each adjusting lever 233 and configured to be corresponsive to the hook 2322, and the first fixed portion 2331 is clamped to the hook 2322 to define a connection. In addition, the rear end of each adjusting lever 233 has a second fixed portion 2332, and the staggered multilayer trimming head further has three lever switches 236, and each lever switch 236 has a bump 2361, and the second fixed portion 2332 is capable of clamping and fixing to the bump 2361, so that each lever switch 236 and each respective adjusting lever 233 are coupled to each other, and each lever switch 236 is disposed in each respective window 211 to facilitate adjusting the position of each second moving knife 232.
