[0030] Further, the number of teeth 2 in the sawtooth group is three, a second arc-shaped groove 6 is provided between the three teeth 2, the width of the second arc-shaped groove 6 is less than that of the first arc-shaped groove 5, the design of the three teeth 2 in each set of sawtooth group can ensure the cutting effect and reduce the production cost, and the connection strength between the three teeth 2 is ensured by the provision of the second arc-shaped groove 6 to avoid exercise, and the width of the first arc-shaped groove 5 is greater than that of the second arc-shaped groove 6, which can improve the heat dissipation effect while ensuring that the multiple sawtooth groups can continuously cut the wall, avoid the arrangement of the teeth 2 being too dense, and enhance the chip removal space.

The driving wheel 8 and the limiting wheel 10 on the cutting mechanical equipment body 11 are all devices known to those skilled in the art, which can refer to the high-frequency ring saw cutting machine produced by the Douyin E-commerce, the master high-frequency ring saw cutting machine, and the high-frequency brushless ring saw cutting mechanical equipment body 11 produced by Donglai Hardware and Electrical Co., Ltd. It is used with the saw blade in the present application. The installation structure is shown in the schematic diagram Figure 5 .

[0033] It should be noted that the thickness of the PCD diamond composite blade 3 is greater than the thickness of the tooth 2. Please refer to Figure 7 , through the design that the thickness of the PCD diamond composite blade 3 is greater than the thickness of the tooth 2, the gap generated on the wall during cutting will be slightly larger than the thickness of the tooth 2 and the annular base body 1, so when the card is stopped or needs to be reversed, the saw blade is reversed, and the resistance is reduced.
