[0031] Therefore, during assembly and use, it is easy to support the assembly inside the shredder via the outer support shaft 102 for auxiliary drive rotation, making operation more convenient.

[0032] Working principle: During assembly, according to usage requirements and blade spacing, a corresponding number of circular blades 110 are fitted and assembled with the cooperation of the assembly shaft 100 and the limiting roller 101. The cooperation of the inner thread groove 131 and the hidden groove 132 facilitates auxiliary threaded insertion and positioning via the limiting screw 130, making the assembly of the circular blades 110 more convenient and stable. The filling of the inner spacer 120 further facilitates the assembly between the circular blades 110 and makes subsequent disassembly and replacement easier. Subsequently, with the cooperation of the outer support shaft 102, it is docked and driven with the shredder. During use, the boss 113 helps maintain the roundness of both sides of the blades during shredding, and the filling of the inner spacer 120 prevents residue from being left behind by the shredded material, making operation more convenient and efficient. The operation is now complete.
