ABSTRACT:
A circular cutter includes a bracket-mounting part integrally formed with a base plate as a single piece. The bracket-mounting part defines a first abutting face. A bracket is pivoted to the bracket-mounting part through a pivot shaft. The bracket defines a second abutting face, and is formed with an arcuate slot. A cutter-holding arm is pivoted to the bracket. A friction-providing plate is interposed between the first and second abutting faces. A screw rod extends through the arcuate slot and the friction-providing plate to threadedly engage an inner thread in the bracket-mounting part.
