the cutting knife is provided with at least two rows of second connecting hole groups, the two rows of second connecting hole groups are arranged at intervals, each row of second connecting hole groups comprise a plurality of second connecting holes, and one second connecting hole is arranged corresponding to one first positioning hole;

the first external connecting piece is used for sequentially connecting the second connecting hole and the first positioning hole to install the cutting knife on the knife holder, and the cutting knife and the installation surface enable the cutting knife to be in a spiral shape.

Further, the tool apron is provided with a tool groove which is formed by concavely arranging the mounting surface, the first positioning hole group is positioned in the tool groove, and the cutting tool is arranged in the tool groove.

Furthermore, the second connecting hole is in a long-strip hole shape.

Further, one first positioning hole of one row of the first positioning hole groups is positioned between two adjacent first positioning holes in the other row of the first positioning hole groups.

Further, the blade holder still includes a plurality of adjustment hole, and the adjustment hole is established from the trompil face of blade holder and is formed by concave, the trompil face with installation face cross arrangement, external adjustment spare passes the adjustment hole is contradicted with cutting the sword.

Further, the adjusting hole is a threaded hole.

The invention has the beneficial effects that: through setting up the spiral helicine sword that cuts make when cutting the sword and rotate along with the rotor, cut the sword and take place point type instantaneous contact with the lower blade that is located the cutting machine, reduce the impact force, the setting of the first location punch combination of multirow, multirow second connection punch combination simultaneously realizes cutting the characteristics that the sword has the multirow location, prevents to cut the sword and takes place elastic deformation, improves and cuts the quality.
