[0023] Reference Figure 1 and Figure 2 The hand grip strengthener shown includes a ring-shaped body 1, two electrode plates 2, a control device 3, and a power supply device 4. The two electrode plates 2 are disposed on the outer surface of the ring-shaped body 1, while the control device 3 and power supply device 4 are disposed within the ring-shaped body 1. Both the two electrode plates 2 and the power supply device 4 are electrically connected to the control device 3, and the power supply device 4 also supplies power to the two electrode plates 2. In this embodiment, the control device 3 can be a conventional circuit board with control functions, and the power supply device 4 is a rechargeable battery. A segment of the ring-shaped body 1 corresponding to a finger is made of an elastic material, allowing the user to grip this elastically deformable segment to strengthen hand muscles. Two electrode plates 2 are divided into positive and negative electrodes and are spaced apart on the outer surface of the annular body 1. The two electrode plates 2 correspond to the thenar and hypothenar muscles of the palm, respectively, and are used to transmit electrical stimulation signals to the muscles to realize the EMS function. That is, both positive electrodes 2 are in contact with the palm to realize current conduction. The two electrode plates 2 send low-frequency electrical pulses to the thenar and hypothenar muscle groups to simulate nerve signals, stimulate the thenar and hypothenar muscle groups to contract, thereby promoting the strengthening of muscle fibers and the increase of strength in the thenar and hypothenar muscle groups.

[0024] In some possible embodiments, one of the electrode pads 2 forms an arc-shaped protrusion 21 on the outer surface of the annular body 1. The arc-shaped protrusion 21 can abut against the palm recess between the thenar and hypothenar muscles, making the electrode pad 2 fit more closely to the palm and improving the effect of electrical stimulation.

[0025] In some possible embodiments, the annular body 1 includes a rigid grip portion 11 and an annular silicone 12. The annular silicone 12 is fixedly installed at both ends of the rigid grip portion 11, which not only increases the comfort of gripping but also provides a certain degree of cushioning and protection.

The electrode sheet 2 can be fixed and attached to the outer surface of the electrode sheet mounting portion 6 by means of adhesion, riveting or buckling, and the electrode sheet mounting portion 6 is buckled and fixed to the outer surface of the hard hand holding portion 11. In order to improve the hand feeling, the electrode sheet 2 is usually made of a thin metal sheet or a conductive silica gel sheet. In the present embodiment, the electrode sheet 2 is attached to the electrode sheet mounting portion 6 made of hard insulating material, which not only retains the contact feeling of the electrode sheet 2, but also increases the structural strength of the electrode sheet 2, thereby avoiding the problem of deformation of the electrode sheet 2 under pressure.

[0029] In some possible embodiments, a control button 7 is arranged on the hard hand holding portion 11 corresponding to the thumb, and the control button 7 is electrically connected with the control device 3. The user can conveniently operate or switch various functions of the handgrip, such as adjusting the intensity of electric stimulation, controlling the heating temperature, and the like, through the control button 7.
