The shaft core is inserted into the shaft sleeve 3 and can rotate. At least two wheels 23 are fixed at the bottom of the frame structure. The two wheels 23 can roll back and forth along the horizontal workbench 12. The two wheels 23 and the shaft core jointly support the frame structure. The frame structure is preferably a trapezoidal structure, and the position close to the sawing machine body is relatively wide, so that a relatively large plate 9 can be placed.

The other end of the sheet material 9 is also placed on the frame structure of the swing frame and can slide along the frame structure under the push of the movable horizontal frame 81. Since the sheet material 9 can slide on the frame structure and the contact area is relatively small, the overall friction force is not large and the required thrust is relatively small.

[0053] The housing of the pressing plate cylinder 73 is fixed to the movable horizontal frame 81 through the pressing plate bracket 71, and the connecting rod is fixed to the pressing block 72. The pressing block 72 can press the edge of the sheet 9 to the movable horizontal frame 81. The pressing plate cylinder 73 is connected to the air pump through the manual valve. The pressing action can ensure the accurate positioning of the sheet 9 and the processing size.

[0054] A driving device capable of controlling the movable frame to move only along the length direction of the central rod 22;

[0055] The swing frame can be manually controlled to swing around the sleeve 3, and the sheet material 9 can move horizontally in an arc around the sleeve 3 and be cut into an arc shape by the saw 13; the driving device can be manually controlled to move the movable frame forward a predetermined distance, so that the sheet material 9 can be cut into pieces of arc wood 91 with equal arc degrees.
