[0031] In some embodiments, as Figure 7 As shown, the end surface of the second clamping module 33 away from the clamping base 31 is provided with a scale value for measuring distance.

[0032] In some embodiments, as Figure 5 、 Figure 6 、 Figure 8 As shown, the clamping unit 3 also includes an angle measuring module 10, on which an angle value and a positioning hole 11 are set; a positioning column 35 corresponding to the positioning hole 11 is fixedly provided on the end face of the first clamping module 32 away from the clamping base 31; the positioning hole 11 can be coupled and connected with the positioning column 35.

[0036] The working principle of this utility model is:

[0037] First, a rock sample (not shown) is secured within the sliding box 5. The handle 8 engages the nut at the end of the screw 34, and the handle 8 is pulled, causing the screw 34 to rotate. The screw 34 drives the first clamping module 32 and the second clamping module 33 to move away from or toward each other. When the distance between the first clamping module 32 and the second clamping module 33 reaches a predetermined distance, the clamping module 9 (which is rectangular in shape, with the drill teeth 7 fixedly connected thereto and the end of the drill bit 7 perpendicularly fixedly connected to a surface of the clamping module 9) is placed between the first clamping module 32 and the second clamping module 33. The depth and angle of the drill teeth 7 on the clamping module 9 entering the rock sample are adjusted as needed (the angle is adjusted by aligning the edge of the clamping module with the angle value on the angle measurement module 10, which can then be calculated using conventional methods). Finally, the handle 8 is pulled, causing the screw 34 to drive the first clamping module 32 and the second clamping module 33 to clamp and secure the clamping module 9. The controller turns on the motor 6 and controls the speed of the motor 6 (the motor 6 can be a stepping motor 6). The motor 6 drives the screw to rotate at a certain speed. The screw pushes the sliding box 5 to move close to the drill bit teeth 7. Then the drill bit teeth 7 cut the rock sample. The pressure sensor 4 uploads the pressure between the rock sample and the drill bit teeth 7 to the controller. Combined with the pressure uploaded by the pressure sensor 4 and the changes in the drill bit teeth 7 when cutting the rock sample, the changes in the drill bit teeth 7 and the rock cutting under different pressure conditions can be intuitively analyzed.

[0038] By fixing the drill bit on the clamping unit 3, fixing the rock sample in the sliding box 5, and driving the sliding box 5 to move by the driving unit and perform linear cutting with the drill bit, the changes in the drill bit teeth can be observed intuitively, thereby solving the problem that it is difficult to observe the changes in the drill bit teeth when drilling with the existing drill bit.

[0039] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present disclosure.
