When the cutter disc 302 rotates clockwise, it drives the transmission gear 601 to engage with the inner side of the outer gear block 603. The transmission gear 601 rotates to drive the screw rod 501 to rotate and cause the tool holder 7 to descend. When the tool needs to be switched, the cutter disc 302 rotates to drive the transmission gear 601 to engage with the outer side of the inner gear block 602, causing the screw rod 501 to rotate in the opposite direction to drive the lifting plate 502 to rise and retract the tool holder 7 into the tool groove 401.
