Combination double blade blade is to be assembled by stack by interior cutter (1) and outer cutter (2), be fixed together by spot welding then, because interior cutter (1) and (2) two blades of outer cutter all are made of metal, therefore can provide enough weight, make blade stablize rotation, do not shake and skew and can not rotate, interior cutter (1) and outer cutter (2) all are to pass through a die cut moulding of mould respectively, therefore can keep higher making precision, when assembling, can keep the center of circle coaxial, it is intracardiac in the cutter (2) outside by the injection machine single injection-molded to connect rotatable lamella (5), outer like this cutter (2) be connected rotatable lamella and also can keep center of rotation coaxial, therefore, when combination double blade rotary electric sharer cutter head installs, connect rotatable lamella (5), interior cutter (1), outer cutter (2) can keep center of rotation coaxial with cutter cover (6), makes up double blade rotary electric sharer cutter head like this under motor drives, colory rotation sound is sent in energy stable operation.

Because a bit of a little place of cutting edge (22) and its underpart of the combination double blade blade of combination double blade rotary electric sharer cutter head, adopt the punch forming technology that one eccentric R groove (13) is set, this structure makes that cutting edge two width edge lengths are unequal, be that cutting edge broadside a is longer than cutting edge broadside b, this makes blade can have thin thickness and higher sharpness, also have with cutter cover net simultaneously enough contact-making surfaces are arranged, and be unlikely to when blade turns round, the phenomenon that gets stuck because of stressed generation cutting edge, because we can make the net seam of the length of cutting edge broadside a greater than cutter cover net, when the length of cutting edge broadside a net seam width, just can well prevent that cutting edge is because of the stressed phenomenon that gets stuck greater than cutter cover net.
