Specifically, when the water pump 10 is running, the water in the water tank 9 can be pumped out, and then sprayed to the diamond drill bit 2 through the water delivery pipe 11 and the water spray head 13, so that the diamond drill bit 2 can be cooled down during the process of the diamond drill bit 2 drilling into the stone 3, so as to well simulate the scene when the diamond drill bit 2 is actually used, and effectively improve the reliability of the test result;

[0025] The protection component includes a transparent protection panel 14, the bottom of which is fixed at the middle of the top of the base 1, and a transparent door panel 15 is hinged at the front end of the transparent protection panel 14. The stone 3 is located inside the protection panel 14 and the transparent door panel 15. Therefore, under the action of the transparent protection panel 14 and the transparent door panel 15, the debris generated when the diamond drill 2 drills into the stone 3 can be effectively prevented from splashing everywhere, thereby avoiding injuries to personnel. Moreover, technicians in the field can take and put the stone 3 by opening and closing the transparent door panel 15, which is convenient to use. Moreover, the transparent protection panel 14 and the transparent door panel 15 can facilitate technicians in the field to observe the use of the diamond drill 2.

[0026] The clamping assembly includes two threaded holes 16, which are symmetrically arranged at both ends of the transparent protective enclosure 14.

[0030] Then the technician in the field starts the electric drill 6 and the electric push rod 5. When the electric push rod 5 is running, it can drive the top plate 4 to move downward for feeding motion. When the electric drill 6 is running, it can drive the drill rod 7 and the diamond drill bit 2 to rotate, so as to descend and drill into the stone 3. The technician in the field can understand the drilling amount of the drill rod 7 and the diamond drill bit 2 on the stone 3 through the scale line 8, and then calculate the life of the diamond drill bit 2 according to the corresponding wear conditions. Under the action of the transparent protective enclosure 14 and the transparent door panel 15, the debris generated when the diamond drill bit 2 drills into the stone 3 can be effectively prevented from splashing everywhere, thereby avoiding injuries to personnel.

[0031] When the diamond drill bit 2 drills into the stone 3, the technicians in this field can also turn on the water pump 10. When the water pump 10 is running, the water in the water tank 9 can be pumped out, and then sprayed to the diamond drill bit 2 through the water pipe 11 and the water spray head 13, so that the diamond drill bit 2 can be cooled in the process of the diamond drill bit 2 drilling into the stone 3, thereby well simulating the scene when the diamond drill bit 2 is actually used, effectively improving the reliability of the test results, and the cooling water sprayed by the water spray head 13 can flow downward into the water collecting tank 20 after cooling the diamond drill bit 2, and finally discharged through the drain hole 21.
