When leather cutting operation is required, first lay the leather on the placement table, then adjust the cutting position, then press the four corners of the leather with the pressing plate, and then start the output rod of the telescopic push rod 202 to extend until it pushes the fixed seat 203 and the flattening roller 204 below the fixed seat 203 to contact the leather. At this time, the lowest end of the cutting tool 130 is above the lowest point of the flattening roller 204. Then the operator holds the pulling and pushing handle 140 and pushes the tool body 120 with the flattening roller 204 to slide along the guide rail 112 to realize the flattening operation of the part to be cut of the leather to be cut. Then the output rod of the telescopic push rod 202 can be retracted until the flattening roller 204 contacts the upper surface of the leather. At this time, the lowest end of the cutting tool 130 is below the lowest point of the flattening roller 204. Then continue to hold the pulling and pushing handle 140 and push the tool body 120 with the cutting tool 130 to move along the guide rail 112 to realize the cutting operation. The present utility model can realize the pressing and flattening operation of the leather to be cut near the cutting tool 130 through the flattening and pressing mechanism provided on the cutting mechanism 100, solving the problem that when leather is cut, a fixing device is needed to press and fix it before cutting.
