Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this high-strength thin-film blade with replaceable cutting head includes a blade body with a through mounting hole 1 at the center and a cutting head 2. The blade body consists of three overlapping layers: an upper blade layer 3, a middle blade layer 4, and a lower blade layer 5. The upper blade layer 3 has mounting grooves 7 on both sides for mounting the cutting head 2. The mounting grooves 7 have positioning grooves 8 for limiting the cutting head 2. The upper blade layer 3 has mounting posts 6 below it for stacking with the middle blade layer 4 and the lower blade layer 5. The middle blade layer 4 has fixing grooves 9 on both sides that communicate with the positioning grooves 8. The middle blade layer 4 has reinforcing ribs 10 embedded in it. The lower blade layer 5 has mating holes 11 for the mounting posts 6 to pass through. The mating holes 11 penetrate the lower blade layer 5 and the middle blade layer 4. The cutting head 2 has a mounting part 12 below it that can extend from the positioning groove 8 to the bottom of the fixing groove 9. The mounting part 12 also has mounting posts 6 below it. The lower end of the mounting posts 6 has screw holes 13.

[0024] It also includes a screw portion 16 for cooperating with the mounting post 6. A cylindrical filling portion 14 is provided on the screw portion 16.
