The hand winch 9 pulls the wood to slide upward along the guide frame 7 through the wire rope. When the wood slides onto the load-bearing beam 16, the wire rope is released, and the wood is firmly fixed by the fixing device of the bed frame 1, and then the guide frame 7 is removed from the vertical plate 11. The height of the load-bearing beam 16 can be adjusted by rotating the adjusting screw 141, which has a better supporting effect on wood of different sizes and shapes, and makes the stability and levelness of the wood better, thereby improving the effect of sawing wood.

[0042] A guide frame 7 and a traction frame 8 are respectively arranged on the vertical plates 11 on both sides of the bed frame 1. A hand winch 9 is arranged on the traction frame 8. The steel wire rope of the hand winch 9 is passed around the wood to fix the wood. Then, the wood is pulled along the guide frame 7 to the load-bearing beam 16 of the bed frame 1 by rotating the hand winch 9. The transportation of the wood does not require special equipment, and it is more convenient to transport the wood to the sawing machine.

[0043] Loosen the locking sleeve 13 so that the saw frame 2 can slide along the bed frame 1, and then start the band saw mechanism 3 to cut the wood. The band saw mechanism 3 is provided with a woodworking band saw blade for cutting the wood. The band saw mechanism 3 is a prior art and will not be described in detail here.

[0044] After the sawing machine is used, the saw frame 2 is fixed by the locking sleeve 13, and then the hand jack 6 and the universal wheel 53 are raised, and then the trailer hook 52 is connected to the trailer to transport the sawing machine to the next site.
