Further, described serrated knife wheel for overall in the form of a ring, periphery is evenly arranged the cutter of some sharp tooth cutting edges.
Further, each straight pin is respectively installed with more than two or two arranged superposed and the serrated knife wheel that can rotate around straight pin.
Further, described revolving part is provided with more than three or three straight pins be uniformly distributed circumferentially.
Further, described revolving part comprises two and is oppositely arranged and the fixed disk be fixed together, and each straight pin is all fixed between two fixed disks, and two fixed disks offer an installing hole respectively, and the axial line of two installing holes overlaps.
Further, in two described fixed disks, the end face of the first fixed disk is provided with its on the stepped central axle sleeve of installing hole concentric, the end face of the second fixed disk is provided with its on the annular boss of installing hole concentric, the small end of described stepped central axle sleeve stretches in the installing hole of annular boss and the second fixed disk, and the large end of described stepped central axle sleeve coordinates with convex annular deck contact.
Further, described first fixed disk is provided with the first screw hole of several large end through described stepped central axle sleeve, described second fixed disk is provided with several the second screw hole through described annular boss, is linked together by hexagon socket head cap screw between each first screw hole and the second screw hole corresponding with it.
Further, the two ends of each straight pin are respectively arranged with a shaft shoulder, and described first fixed disk and the second fixed disk are respectively equipped with the locating hole coordinated with the described shaft shoulder.
Further, each straight pin is arranged around the periphery of described stepped central axle sleeve and annular boss.
Compared with prior art, the utility model tool has the following advantages:
First, the utility model cutter head includes at least two or the two groups serrated knife wheels along the circumferential direction distributed, during fluting, each serrated knife takes turns periodic duty successively in wall surface, can improve stock-removing efficiency, simultaneously, the sharp tooth cutting blade structure of each serrated knife wheel periphery is more conducive to cutting body of wall, improves cutting force, and reduces the power output of the power set of groover thus, realize energy-conservation, efficient, the object reduced costs.
Secondly; each serrated knife wheel of the utility model cutter head is rotatable to be arranged; when therefore slotting; the sharp tooth cutting edge of serrated knife wheel periphery can participate in the cutting of surface of wall successively; cutwork is shared, the appearance wearing and tearing avoiding cutting edge too early because of overload operation, thus play the effect of protection cutting edge on the one hand; extend its application life, also can guarantee the reliability of work on the other hand.
