Abstract
A device for measuring grip strength includes a shaft received in a base and a cable is wrapped on the shaft. The cable includes a first end to which the user applies a grip force and a fixed second end. A disk is connected to an end of the shaft and includes a plurality of protrusions and recesses defined between the protrusions. A detection member is located beside the disk and the protrusions pass through the detection member when the shaft is rotated by the user. A transferring unit is connected to the base and includes a fixed part and an operation unit movably connected to the fixed part. A rod is movable with the operation unit and connected to the first end of the cable. A biasing unit includes a spring which returns the rod when the user releases the rod.
