Figure 1-5 As shown, a cross-cutting saw blade according to the present invention comprises a first plywood 1, a second plywood 2 and a saw blade 5, wherein the saw blade 5 comprises saw teeth 6 at the bottom, and the first plywood 1 and the second plywood 2 are respectively located on both sides of the top of the saw blade 5;

[0026] Both ends of the saw blade 5 are penetrated by second through holes 19, and both ends of the first plywood 1 strip connecting plate 3 and the second plywood 2 are penetrated by first through holes 18 corresponding to the second through holes 19. A circular hole 9 is provided at the bottom of the saw blade 5 near the teeth 6, and a first round chamfer 10 is provided at the bottom opening of the circular hole 9. Reserved grooves 15 are provided at the bottom of the first plywood 1 and the second plywood 2, and arc-shaped support blocks 16 are provided on the inner walls of the first plywood 1 and the second plywood 2 near the edges of the reserved grooves 15, and the arc-shaped support blocks 16 are located in the corresponding circular holes 9.

[0027] During use, external bolts are passed through the first through hole 18 and the second through hole 19 to conveniently fix the first plywood 1 and the second plywood 2 to the outside of the top of the saw blade 5. When the teeth 6 at the bottom of the saw blade 5 are cutting, the debris generated in the cutting groove will enter the first round chamfer 10, and the chips will be discharged through the first round chamfer 10. The circular hole 9 can be supported by the arc-shaped support block 16 to prevent the circular hole 9 from having insufficient strength. This saw blade has a structure that can conveniently discharge the debris generated during cutting, which can effectively prevent the debris from being blocked inside the groove generated by cutting and affecting the cutting effect.

[0028] For example, Figure 1-5As shown, the utility model also includes a second positioning hole 17 that is opened through one side of the saw blade 5 near the second through hole 19, and first positioning holes 7 are opened at both ends of the first plywood 1 and the second plywood 2 at positions corresponding to the second positioning hole 17, and positioning columns 8 are provided on the inner wall of the second plywood 2 near both ends, and the positioning columns 8 pass through the corresponding second positioning holes 17 and the first positioning holes 7.

[0029] During use, the positioning post 8 passes through the second positioning hole 17 and the first positioning hole 7 , so as to facilitate pre-positioning before connecting the first plywood 1 and the second plywood 2 .

[0030] For example, Figure 1-3 As shown, the present invention further includes that a strip connecting plate 3 is provided on the top of the second plywood 2 , and threaded holes 4 are penetrated through one side of the strip connecting plate 3 near both ends.

[0031] When in use, the strip connecting plate 3 is conveniently connected to the driving mechanism of the external saw blade by passing the external bolt through the threaded hole 4, so that the saw blade is driven to move by the external driving mechanism.

[0032] For example, Figure 1-3 As shown, the present invention further includes a positioning groove 14 penetrating through one side of the strip connecting plate 3 near the center.

[0033] During use, a positioning protrusion corresponding to the positioning groove 14 is provided on the connecting structure of the external driving mechanism, so that the connecting structure of the external driving mechanism can be pre-positioned before being connected to the strip-shaped connecting plate 3 .

[0035] During use, the first chamfer 11 and the second chamfer 12 can effectively reduce the possibility of damage to the top corners of the first plywood 1 and the strip connecting plate 3 .

[0036] For example, Figure 1 and 5 As shown, the present invention further includes that second round chamfers 13 are provided at both ends of the top of the saw blade 5 near the corners.

[0037] During use, the second round chamfers 13 can effectively prevent the two ends of the top of the saw blade 5 from being easily damaged by collision.

[0038] When the present invention is in use, the external bolt passes through the threaded hole 4, which makes it convenient to connect the strip connecting plate 3 with the driving mechanism of the external saw blade, so that the saw blade is driven to move by the external driving mechanism, and the positioning column 8 passes through the second positioning hole 17 and the first positioning hole 7, which makes it convenient to pre-position the first plywood 1 and the second plywood 2 before connecting them, and the external bolt passes through the first through hole 18 and the second through hole 19, which makes it convenient to fix the first plywood 1 and the second plywood 2 to the outside of the top end of the saw blade 5. When the teeth 6 at the bottom of the saw blade 5 are cutting, the debris generated in the cutting groove will enter the first round chamfer 10, and the chips are discharged through the first round chamfer 10, and the circular hole 9 can be supported by the arc-shaped support block 16 to prevent the circular hole 9 from having insufficient strength. The present saw blade has a structure that can conveniently discharge the debris generated during cutting, which can effectively prevent the debris from being blocked in the groove generated by cutting and affecting the cutting effect.
