The detachable blade (20) is mounted in the receiving area (13) of the holding body (10) and has a second engaging portion, and the second sharp part of the second engaging portion engages with the first sharp part of the first engaging portion. The fixing element is securely mounted through the holding body (10) and the detachable blade (20). The detachable blade (20) can disassemble from the holding body (10), and thus one holding body (10) could be installed with detachable blades (20) of various dimensions. As the detachable blade (20) is damaged, the damaged detachable blade (20) is replaced with a new detachable blade (20) to keep processing.
