If there is a description of the first and the second, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0030] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0031] Please refer to Figures 1-9 , the present utility model provides a technical solution: a diamond cutting blade for preventing edge chipping, including a first component 2, and a cutting blade device for preventing the overall cutting blade from chipping is arranged on the surface of the first component 2;

[0032] The cutting blade device includes a plurality of mounting stoppers 10, the surfaces of the plurality of mounting stoppers 10 are fixedly connected to the surface of the first component 2, the surfaces of the plurality of mounting stoppers 10 are fixedly connected to two plastic hemispheres 9, and the material of the plurality of plastic hemispheres 9 is plastic;

[0033] Among them, four diamond cutting blades 1 are arranged on the surface of the first component 2, and two mounting grooves 13 are provided on the surface of the four diamond cutting blades 1. The surfaces of multiple mounting grooves 13 are in contact with the interior of the corresponding mounting limit members 10, and two second grooves 12 are provided inside the multiple mounting grooves 13. The interiors of multiple second grooves 12 are in contact with the surfaces of the corresponding plastic hemispheres 9.

[0034] A second component 3 is disposed outside the first component 2 , and a surface of the second component 3 contacts surfaces of the four diamond cutting blades 1 .

[0035] A plurality of first grooves 8 are formed on the surface of the second component 3 , and first threaded holes 7 are formed inside the plurality of first grooves 8 .

[0036] The interiors of the plurality of first threaded holes 7 are all threadedly connected with screws 6 , and the plurality of screws 6 are all in contact with the interiors of the corresponding first grooves 8 .

[0037] Second threaded holes 11 are formed on the surfaces of the plurality of mounting stoppers 10 , and the interiors of the plurality of second threaded holes 11 are threadedly connected to the surfaces of the corresponding screws 6 .

[0038] A first mounting hole 4 is provided on the surface of the first component 2;

[0039] A second mounting hole 5 is formed on the surface of the second component 3 .

[0040] When one of the four diamond cutting blades 1 has chipped edges, it is necessary to replace the damaged diamond cutting blade 1, remove the screws 6 corresponding to the chipped diamond cutting blade 1 with an external tool, and then pull the chipped diamond cutting blade 1 with an external force to make it disengage from the gap between the first component 2 and the second component 3, and then replace it with a new diamond cutting blade 1 to move. The movement of the new diamond cutting blade 1 drives the corresponding two mounting grooves 13 to move, and the movement of the two mounting grooves 13 drives the corresponding two second grooves 12 to overlap and get stuck with their corresponding plastic hemispheres 9. Finally, install the corresponding screws 6 back, so that the partial chipping will not affect the overall tool.

[0041] By arranging four diamond cutting blades 1 in the cutting blade device and separately installing them between the gaps of the first component 2 and the second component 3, when a certain diamond cutting blade 1 is damaged, the other diamond cutting blades 1 will not be affected, that is, the chipping of their cutting tools will not affect each other, thus avoiding the phenomenon that the entire diamond cutting blade cannot cut normally due to the chipping of some diamond cutting blades. When partial chipping occurs, the damaged diamond cutting blade 1 can be removed and replaced with a new one without disassembling and replacing the entire cutting blade device, thereby improving the utilization rate of the cutting blade device.

[0042] By arranging a plurality of plastic hemispheres 9 to cooperate with their corresponding second grooves 12, when installing the diamond cutting blade 1, the diamond cutting blade 1 is set at a constant position of the first component 2 through the cooperation of the plastic hemisphere 9 and the second groove 12. Furthermore, it is ensured that all four diamond cutting blades 1 are set at the preset constant positions, so that when the four diamond cutting blades 1 rotate, only one circle is formed, thus ensuring the unity of cutting of the four diamond cutting blades 1.

[0043] Working principle: When there is chipping of the cutting tool among the four diamond cutting blades 1, it is necessary to replace the chipped and damaged diamond cutting blade 1. Remove the screw 6 corresponding to the chipped diamond cutting blade 1 with an external tool, and then pull the chipped and damaged diamond cutting blade 1 out of the gap between the first component 2 and the second component 3 by an external force. Then replace it with a new diamond cutting blade 1 to move. The new diamond cutting blade 1 drives the corresponding two mounting grooves 13 to move. The two mounting grooves 13 drive the corresponding two second grooves 12 to coincide and be stuck with their corresponding plastic hemispheres 9. Finally, install the corresponding screw 6 back.

[0044] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
