[0048] In this embodiment: the rotating shaft 52 is driven to rotate in the supporting frame 51 by the fixing frame 55, thereby driving the fixing pad 53 and the rubber pad 54 to clamp and fix the material body 3.

[0049] Going further:

[0050] In an optional embodiment, a second spring 56 is symmetrically provided on the outer side wall of the rotating shaft 52 , and two ends of the second spring 56 are respectively fixedly connected between the supporting frame 51 and the fixing pad 53 .

[0052] The working principle and use process of the utility model are as follows: first, the material body 3 is placed on the top of the placing block 2, and then the fixing frame 55 is held to rotate the rotating shaft 52, so that the rotating shaft 52 rotates and moves downward in the supporting frame 51, thereby pushing the fixing pad 53 to move downward, and then driving the rubber pad 54 to move downward, so that the bottom of the rubber pad 54 is closely fitted with the top of the material body 3, thereby enhancing the firmness of the plate fixation, and the downward movement of the fixing pad 53 is stabilized by the second spring 56, and then the electric telescopic rod 412 is started to open, and the contact block 418 is driven by the electric telescopic rod 412 to contact the material body 3. At this time, the pressure sensor 416 starts to work under the pressure of the contact block 418, and the pressure display screen 419 can be used to The pressure value can be checked. When the pressure value reaches the detection rated value, the electric telescopic rod 412 is closed. When the contact block 418 contacts the material body 3, the sliding column 414 squeezes the first spring 415 in the sleeve 413 to deform and generate elastic force, thereby detecting the hardness of the material body 3 through the contact block 418. Then, the motor 43 is turned on. The operation of the motor 43 drives the threaded rod 41 to rotate, thereby driving the sliding plate 44 to move in the sliding groove 45, and then driving the connecting seat 46 to move. The moving block 410 is driven to move on the screw rod 47 by rotating the hand wheel 48. The movement of the moving block 410 and the sliding plate 44 can drive the contact block 418 to perform hardness detection on any position of the material body 3.
