A pressure head mounting seat 2 is fixedly connected to the hardness tester body 1. Both sides of the bottom end of the pressure head mounting seat 2 are provided with plug-in slots 3. The two plug-in slots 3 are symmetrically provided with card slots 4 at one end away from each other. The inner walls of the two plug-in slots 3 are provided with There is a mounting plate 5, with grooves 6 at the four corners of the bottom end of the mounting plate 5. The four grooves 6 are fixedly connected to a plurality of springs 7 at one end close to each other, and the four groups of springs 7 are fixedly connected to a movable plate 8 at one end away from each other. The four movable plates 8 and the grooves 6 are slidably connected, and the four movable plates 8 are fixedly connected to a card column 9 that is adapted to the shape of the card slot 4 at one end away from each other and passes through the mounting plate 5. A camera body 10 is fixedly connected to the mounting plate 5, and the position of the indentation can be clearly observed through the camera body 10, and the image of the indentation can be directly captured.

[0026] The power plug 12 is inserted into the power interface 11 and supplies power to the camera body 10 through the cable 15 .

[0027] In this embodiment, the top of the camera body 10 is provided with first limiting grooves 16 on the outer side of the power interface 11, which are matched with the limiting columns 14 in shape and are equal in number;

[0028] The limiting post 14 is inserted into the first limiting groove 16 to position the fixing plate 13 and prevent the fixing plate 13 from rotating during the installation process.
