[0026] The specific settings and effects of the present embodiment will be described below. Diamond particles are mixed with metal powders such as cobalt, nickel, iron, etc. to form the tool bit raw material. These metal powders will melt at high temperatures and play a role in bonding the diamond particles. Then the mixed raw material is placed on the outer peripheral part of the substrate 13, and sintering is performed by a high-temperature sintering furnace to form the diamond saw tooth 11. During the sintering process, the temperature usually reaches several hundred degrees Celsius to over a thousand degrees Celsius, and the specific temperature depends on the type of metal binder and diamond. At this time, the metal powder melts and is closely combined with the diamond particles. This metallurgical bonding makes the connection between the saw tooth part and the substrate very firm, and can withstand a large cutting force. The same group of saw blade assemblies 1 is connected to the same drive shaft of a cutting machine. The angle of the helical tooth can be adjusted according to the hardness and toughness of the material. For relatively hard materials, the helical tooth angle can be between 15°-30°. For relatively soft materials, the angle can be appropriately reduced to meet the cutting requirements of diamond saw blades for different materials. Multiple saw blade assemblies 1 are connected and used in combination with the same shaft. When cutting thick materials such as thick wood, metal or stone plates, multiple saw blade assemblies 1 can be used in combination for layered cutting. The substrate 13 is fixed by the pre-tightening force generated by the flange assembly one 2 and the flange assembly two 4 on both sides. The flange plate one 21 is placed on one side of the substrate 13 with its axis aligned. The flange plate two 41 is placed on the other side of the substrate 13. The inner thread cylinder 43 is aligned with the outer thread cylinder 23. The inner thread cylinder 43 is tightened to move the flange plate one 21 and the flange plate two 41 towards each other.

[0029] The use method and working principle of the device are as follows: firstly, the flange plate one 21 is placed on one side of the substrate 13, and after the axis is aligned, the flange plate two 41 is placed on the other side of the substrate 13, the inner threaded cylinder 43 is aligned with the outer threaded cylinder 23, and then the inner threaded cylinder 43 is tightened, so that the flange plate one 21 and the flange plate two 41 move towards each other and clamp the substrate 13;
