[0002] Diamond tools refer to a type of tools with diamond particles or powders as the main elements. According to their uses, they can be divided into: grinding tools, sawing tools, drilling tools, and other tools. Among them, sawing tools mainly include circular saw blades, gang saws, band saws, and wire saws, etc. Currently, common diamond tools are mainly processed by electroplating, thermal curing, and brazing methods. The diamond tools prepared by the brazing process achieve chemical metallurgical bonding between the matrix metal and the diamond. They have strong diamond grain holding strength, high diamond exposure, large chip space, good self-sharpening property, and high cutting efficiency, making it a hot technology.

[0004] The machine body of this device itself has the characteristics of high wear resistance and high hardness. The positioning holes and connection grooves opened on the surface of the machine body facilitate the hanging or bundling fixation of the machine body. By setting the protective shell, it is possible to avoid repeated collisions when the machine body is idle or in transportation, damage the protective film on the surface of the diamond tool, and extend the service life of the machine body.

[0005] However, this device still has the following problems. The device is initially connected to the mounting post through the threaded hole opened at the bottom of the machine body, and then a pair of clamping bolts on both sides of the sleeved protective shell are used to drive a pair of clamping plates to approach and abut against the outer peripheral wall of the machine body. Then, by pulling the pull plate, two sliding plates are driven to slide, and then the machine body is installed and fixed by the bundling belt in the connection groove. The operation steps are cumbersome and complex, and it is difficult to effectively improve the connection efficiency between the device and the external drive assembly. Content of the Utility Model
