Specifically, a pin receiving hole 50 is formed at an end of the elastic member fixing portion 5, and the second engagement end 41 of the elastic member 4 is fixed to a fixing pin 510 provided through the pin receiving hole 50.

The screw hole in the center of the moving plate 711 is screwed with the shaft 700 of the rotary fastening part 70, and the collar 601 is sleeved and fastened by the matching flange 600, so that the moving part 71 can be driven to translate forward and backward in the movable groove 62 through the shaft 700 by the rotation of the rotary fastening part 70, and the moving part 71 can be close to or far from the side end of the elastic part fixing part 5.

When the knob portion 710 is adjusted, the moving piece 711 is movable along the shaft portion 700 of the rotation fastening portion 70 in the elastic member connecting portion 6. When the position of one end portion of the elastic member 4 is changed by the moving piece 711, the strength of the elastic force provided by the elastic member 4 is adjusted by the movement of the first grip 1 and the second grip 2.

The operation of the hand strength exerciser according to the present invention as such is described below.

According to the hand strength exerciser of the embodiment of the present invention, the magnitude of the elastic force provided by the elastic member 4 can be adjusted at the time of the grip movement.

When the user having a large grip uses the hand strength exerciser of the present invention, the knob portion 710 of the rotation fastening portion 70 is rotated in one direction, so that the moving portion 71 to which the one end of the elastic member 4 is fixed is moved in a direction away from the second rotation shaft 80, that is, toward the knob portion 710 side.

When the user with weak grip strength uses the hand strength exerciser of the present invention, the knob portion 710 of the rotation fastening portion 70 is rotated in the opposite direction opposite to the aforementioned direction, and the moving portion 71 is moved to the second rotation shaft 80 side. Whereby the strength of the grip is reduced.

Therefore, according to the present invention, the strength of the hand strength exerciser can be adjusted and utilized in match with the strength of the grip of the user himself.
