In the structure, the double-axe-shaped saw blade body with the upper axe-shaped structure and the lower axe-shaped structure can ensure that the relevance of the deformation of the upper symmetrical saw blade group and the lower symmetrical saw blade group is reduced to the minimum during cutting, when the upper saw blade group or the lower saw blade group leaves a workpiece, the self resilience force of the saw blade body can be utilized to automatically correct the position, and meanwhile, the residual waste chips after cutting by the cutting edge are smoothly discharged along the arc-shaped surface of the arc-shaped notch.
Furthermore, the thickness of the double-axe-shaped saw blade body is gradually thinned to the clamping position at the position of the cutter handle hole along the radial direction, so that the cutting friction force between the double-axe-shaped saw blade body and a workpiece is reduced, and the cutter is prevented from being clamped and the machined surface is prevented from being damaged.
Furthermore, the thinning gradient of the single-side thickness of the double-axe-shaped saw blade body is designed to be 0.5 degrees, so that the original rigidity of the double-axe-shaped saw blade body is effectively maintained.
