Both sides of the limiting slot 301 extend through both ends of the knife holder 3. A knife slot 303 is vertically defined at the bottom of the knife holder 3, and the knife slot 303 communicates with the limiting slot 301.

[0025] The cutting edge of the cutting knife 5 is facing downward, and a cross bar 501 is fixedly connected to the top of the cutting knife 5. The cutting knife 5 matches the knife groove 303, and the cross bar 501 is engaged with the limiting groove 301. Both ends of the knife holder 3 are provided with locking mechanisms. When the cutting knife 5 passes through the knife groove 303 and the cross bar 501 is engaged with the limiting groove 301, the two sets of locking mechanisms respectively position the two ends of the cross bar 501.

[0026] The cutting knife 5 is a replaceable knife. When the blade of the cutting knife 5 in use is rusted or not sharp enough, the knife can be replaced.

[0027] The cutting knife 5 and the knife holder 3 can be spliced ​​and combined, and the cross bar 501 is clamped on the limiting groove 301 of the knife holder 3. The blade of the cutting knife 5 passes through the knife groove 303 and extends out of the bottom of the knife holder 3. At this time, the two ends of the cross bar 501 are positioned by the locking mechanisms on both sides.
