Abstract: The present invention discloses a hand dynamometer structure, comprising a housing, a sensor element provided within the housing, and a gripping part connected to the sensor element. The housing includes a main body having an installation cavity, a connection port at the lower part, and guide members on both sides. The gripping part is positioned between and movable relative to the guide members. The main body and the guide members form an integrated structure. An installation opening is formed at the front or rear side of the main body, with a cover plate at the installation opening. The side wall of the main body is provided with an information screen opening and button openings communicating with the installation cavity. Compared to the prior art, the present invention integrates the side cover directly into the main body, effectively improving the overall strength and reducing the assembly steps, which improves production efficiency.
