[0002] Diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals. Therefore, it can exert its superior performance when processing difficult-to-cut materials, such as cutting ceramics, quartz, glass, etc. The wear rate of diamond tools is very low, which is hundreds or even thousands of times that of ordinary tools. Therefore, its service life is very long, which can reduce production costs and improve production efficiency, and thus be widely used in many fields. When using existing diamond tools, they need to be installed on the cutting equipment first, but the installation of existing equipment involves multiple mounting bolts, which require staff to tighten them one by one. The installation takes a lot of time, which is not conducive to improving the installation efficiency of diamond tools. In view of this, we propose a diamond tool for cutting circular holes in rock slabs. Utility Model Content

[0020] Embodiment 1

[0021] Reference Figure 1-Figure 3 A diamond tool for cutting round holes in rock slabs comprises a mounting base 1, and mounting bolts 3 and a cutting tool 5 arranged on the mounting base 1 for fixed installation. The mounting base 1 is provided with an anti-loosening component 2 for preventing the mounting bolts 3 from loosening, and the mounting base 1 is provided with a mounting component 4 for fixing the cutting tool 5. When the device is used, the mounting base 1 is first mounted on the cutting device through the mounting bolts 3, and then the mounting bolts 3 are limited by the anti-loosening component 2, and then the cutting tool 5 is mounted on the mounting base 1 through the mounting component 4 to wait for cutting;

[0022] The mounting assembly 4 includes a mounting protrusion 41 fixedly mounted on one side of the mounting base 1, and a plurality of restraining plates 42 for restraining the tool 5 are provided on one side of the mounting protrusion 41, and a placement cavity for placing the tool 5 is constructed between the plurality of restraining plates 42, and a fastening sleeve 43 is installed on the external thread of the mounting protrusion 41, and a fastening protrusion 44 that contacts the restraining plate 42 is fixedly installed in the inner cavity of the fastening sleeve 43. During installation, one end of the tool 5 is first placed in the placement cavity, and then the fastening sleeve 43 is rotated to make it slide on the mounting protrusion 41. During the sliding process, the fastening protrusion 44 arranged in the fastening sleeve 43 will squeeze the restraining plate 42 to make it close to the tool 5, thereby achieving the effect of installing the tool 5. In addition, it is only necessary to rotate the setting of the fastening sleeve 43, so that compared with the transmission installation technology, this scheme reduces the steps of rotating each bolt in turn, saves the installation time of the tool 5, improves the installation efficiency of the tool 5, and is conducive to the promotion of the equipment.

[0023] The restraining plate 42 is made of elastic material. The use of the elastic material restraining plate 42 allows the restraining plate 42 to be installed close to the tool 5 under the squeezing of the fastening protrusion 44, and can also automatically open when the fastening protrusion 44 is away, so as to facilitate one end of the tool 5 to be placed in the accommodating cavity 22.

[0024] The fastening sleeve 43 is provided with a plurality of anti-skid patterns 45 on the outside. The design of the anti-skid patterns 45 can significantly increase the friction of the fastening sleeve 43. This design increases the contact area between the palm of the staff and the outer wall of the fastening sleeve 43 by adding textures to the fastening sleeve 43, thereby increasing the friction. In addition, the design of the anti-skid patterns 45 also has a certain aesthetic effect. The special pattern design can not only add a decorative effect to the fastening sleeve, but also enhance the overall visual effect of the cutting device, making it look more beautiful and comfortable.

[0025] General Example 2

[0026] Reference Figure 1-Figure 3 , this embodiment is basically the same as the first embodiment, and is more optimized in that the anti-loosening component 2 includes a dustproof cylinder 21 fixedly mounted on one side of the mounting base 1, and a plurality of accommodating cavities 22 are opened at one end of the dustproof cylinder 21, and a limiting rod 24 is slidably installed inside the accommodating cavity 22, and a limiting spring 23 fixedly connected to the accommodating cavity 22 is provided at one end of the limiting rod 24. During installation, an installation tool such as a wrench will be sleeved on the outside of the fastening end of the mounting bolt 3, thereby squeezing the limiting rod 24 down, and the mounting bolt 3 inserted into the dustproof cylinder 21 can rotate freely. After the installation is completed, the tool is taken out, and under the action of the limiting spring 23, the limiting rod 24 will automatically pop out and fit the edges of the fastening end of the mounting bolt 3, thereby limiting its rotation. When the cutting equipment vibrates, it loosens, thereby improving the cutting stability of the tool 5.

[0027] The cross-section of the dustproof tube 21 is conical, and the diameter of the smallest end is larger than the fastening end of the mounting bolt 3. The setting of the conical cross-section reduces the adhesion of dust on the dustproof tube 21 after the dust falls to the outside of the dustproof tube 21, so that the dust will directly fall off when it falls on the dustproof tube 21. The special setting of the diameter allows the fastening end of the mounting bolt 3 to be close to the port of the dustproof tube 21 to achieve the effect of closing the dustproof tube 21, thereby preventing impurities from entering the inside of the dustproof tube 21 and affecting the rotation of the mounting bolt 3.

[0028] How it works

[0029] When the device is used, the mounting base 1 is first mounted on the cutting device through the mounting bolts 3, and then the mounting bolts 3 are limited by the anti-loosening assembly 2, and then the tool 5 is mounted on the mounting base 1 through the mounting assembly 4 and waits for cutting. During installation, one end of the tool 5 is first placed in the placement cavity, and then the fastening sleeve 43 is rotated to make it slide on the installation protrusion 41. During the sliding process, the fastening protrusion 44 set in the fastening sleeve 43 will squeeze the binding plate 42 to make it close to the tool 5, thereby achieving the effect of installing the tool 5. In addition, it is only necessary to rotate the setting of the fastening sleeve 43, so that compared with the transmission installation technology, this scheme reduces the steps of rotating each bolt in turn, saves the installation time of the tool 5, improves the installation efficiency of the tool 5, and is conducive to the promotion of the device. The use of the elastic material binding plate 42 allows the binding plate 42 to be pressed against the tool 5 to complete the installation under the squeezing of the fastening protrusion 44, and can also automatically open when the fastening protrusion 44 is away, so that one end of the tool 5 is conveniently placed in the accommodating cavity 22. The design of the anti-skid pattern 45 can significantly improve the friction of the fastening sleeve 43. This design increases the contact area between the palm of the staff and the outer wall of the fastening sleeve 43 by adding textures to the fastening sleeve 43, thereby increasing the friction. In addition, the design of the anti-skid pattern 45 also has a certain aesthetic effect. The special pattern design can not only add a decorative effect to the fastening sleeve, but also enhance the overall visual effect of the cutting equipment, making it look more beautiful and comfortable. At the same time, during the installation process, installation tools such as wrenches will be sleeved on the outside of the fastening end of the mounting bolt 3, thereby squeezing the limit rod 24 down. At this time, the mounting bolt 3 inserted into the dustproof tube 21 can rotate freely. After the installation is completed, the tool is taken out. Under the action of the limit spring 23, the limit rod 24 will automatically pop up and fit the edges of the fastening end of the mounting bolt 3, thereby limiting its rotation. When the cutting equipment vibrates, it becomes loose, thereby improving the cutting stability of the tool 5. In addition, the setting of the conical cross-section reduces the adhesion of dust on the dust tube 21 after the dust falls to the outside of the dust tube 21, so that the dust will directly fall off after falling on the dust tube 21. The special setting of the diameter allows the fastening end of the mounting bolt 3 to be close to the port of the dust tube 21 to achieve the effect of closing the dust tube 21, thereby preventing impurities from entering the interior of the dust tube 21 and affecting the rotation of the mounting bolt 3.
