The mechanism places a connecting frame on the cutting table and fixes the connecting frame to the cutting table through a connecting hole using screws or other structures. The CNC machine tool is started to make the cutter cut the clothing fabric. When deviation occurs, the cutting mark is scanned by a track sensor, and then the first motor on the connecting plate is started to rotate the first gear.
