The hand grip exercisers are capable of reliving fatigue, building muscle strength, and improving blood circulation, moreover, regularly training using the hand grip exercisers enables better blood circulation of joints, thereby significantly preventing inflammation and aiding in muscle recovery.

Currently, the hand grip exercisers each generally includes two handles, free ends of the two handles are connected through a spiral elastic component, and the spiral elastic component drives the two handles to returned to original positions after being compressed. For example, Chinese patent having a publication number of CN215461713U and a title of hand grip exerciser discloses two grip exerciser handles connected through an elastic body. For another example, Chinese patent having a publication number of CN210728580U and a title of a hand grip exerciser discloses two grip exerciser handles connected through a spiral elastic body.

To provide users with a more scientific and staged approach to training grip strength and arm strength, current hand grip exercisers are additionally provided with counting functions and grip strength adjusting functions. For example, Chinese patent having a publication number of CN205814970U and a title of a countable and adjustable first spring hand grip exerciser including a first handle and a second handle, the first handle and the second handle are pivotally connected by a rivet, an adjusting first spring is disposed between the first handle and the second handle, an adjusting screw and an adjusting nut are disposed on the second handle, and a sliding slot is defined at an upper end of the second handle A first end of the adjusting first spring is fixedly connected to an upper portion of the first handle, while a second end of the adjusting first spring passes through the sliding slot and is pivotally connected to an upper portion of the adjusting nut, a position of the adjusting first spring within the sliding slot is adjusted through rotating the adjusting nut, thereby changing tension of the adjusting first spring and enabling grip strength adjustment. Moreover, a counting sensor and a display screen are disposed on the first handle of the countable and adjustable first spring hand grip exerciser for recording the number of times that the users grip, so as to achieve a purpose of scientific exercise.
