[0013] Further, the upper and lower ends of the squeezing block are provided with notches, and the notches are communicated with the corresponding material reducing grooves. The provision of the notches avoids water accumulation in the material reducing grooves and reduces the material.

[0014] Further, the hand exercise grip device further comprises a fixing rod and two spherical cap-shaped limiting blocks, the squeezing blocks are located between the two limiting blocks, the two ends of the fixing rod are fixedly connected to the two limiting blocks, the connection between the fixing rod and the limiting block is located at the center of the larger end of the limiting block, the fixing rod is located at the center of the plurality of squeezing blocks, and the fixing rod is screwedly connected to the limiting block. The provision of the limiting block and the fixing rod can limit the limiting block. The screw connection of the fixing rod and the limiting block can adjust the distance between the two limiting blocks, and is convenient to disassemble and assemble.

[0015] Further, elastic members are connected between the two opposite limiting rods. The elastic members can be selected from springs, rubber bands and the like. The provision of the elastic members can adjust the force of holding the grip device by selecting different elastic members, so as to meet the exercise needs of different persons.
