[0025] An adjusting member 3 is provided inside the mounting frame 13, and a detection mechanism is provided inside the adjusting member 3. The detection mechanism is used to detect the hardness of the PDC drill bit. The detection mechanism includes an electric push rod 41, and a pressure block 42 is provided on the top of the electric push rod 41. That is, the pressure block 42 is pushed by the electric push rod 41 to detect the hardness of the PDC drill bit surface.
