[0007] Among them, the first tooth block, the second tooth block, and the third tooth block all include adjacent front tooth portions and rear tooth portions, and the width of the front tooth portions of the first tooth block, the second tooth block, and the third tooth block is the same, and the width of the rear tooth portions of the first tooth block, the second tooth block, and the third tooth block decreases successively, and the front tooth portion and the rear tooth portion are respectively provided with protruding strip-shaped cutter heads.

[0008] According to an embodiment of the utility model, the thickness of the sawing teeth protrudes from the saw blade base by 0.5-1 mm, and the thickness of the strip cutter head protrudes from the sawing teeth by 0.5-1 mm.

[0009] According to an embodiment of the present invention, the arc length of the front tooth portion is smaller than the arc length of the rear tooth portion.

[0010] According to one embodiment of the utility model, the front tooth portion is provided with one strip-shaped cutter head, and the rear tooth portion is provided with two strip-shaped cutter heads.

[0011] According to one embodiment of the utility model, the strip-shaped cutter heads of the rear teeth are of different lengths.

[0012] Compared with the prior art, the utility model can obtain the following technical effects:

[0013] By arranging three tooth blocks with stepped changes on the saw blade base to form sawing teeth, the sawing strength is gradually enhanced. At the same time, the strip cutter heads arranged on top can further enhance the sawing performance and improve the sawing efficiency.

[0014] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
