Connecting device for measuring indentation depth by using displacement meter and use method

The invention discloses a connecting device for measuring indentation depth by using a displacement meter and a measuring method thereof.The connecting device comprises an indenter, the displacement meter and an indenter connecting device, a hole cavity used for installing the indenter is formed in the first end of the indenter connecting device, and the central axis of the hole cavity coincides with the central axis of the indenter connecting device; the displacement meter is parallel to the pressure head, the displacement meter is fixedly connected with the pressure head connecting device through the displacement meter connecting device, the end of the displacement meter is flush with the end of the pressure head, and the displacement meter is used for measuring the indentation action depth of the pressure head. The device and the measuring method thereof have the advantages that the structure is simple, the indentation depth measuring accuracy is high, and the indentation depth measuring result is slightly
