Hand grip

A hand grip comprising:

• a first operating arm and a second operating arm connected to perform a movement of approaching each other and being spaced apart from each other;
• a first connection arm disposed between the first operating arm and the second operating arm to be inclined and having both ends rotatably connected to the first operating arm and the second operating arm;
• a second connection arm disposed under the first connection arm to be inclined in a direction which is the same as that of the first connection arm and having both ends rotatably connected to the first operating arm and the second operating arm;
• a spring member installed to provide an elastic force in a direction interfering with approach of the first operating arm and the second operating arm;
• a spring fixing part formed to extend integrally upward from the first operating arm, wherein one end of the spring member is fixed to an upper end of the spring fixing part;
• a spring connection part formed integrally with the first connection arm and extending obliquely from an upper side of the first connection arm in an outer direction of the hand grip, wherein the spring connection part has a strength adjusting part to which the other end of the spring member is fixed and the spring member is obliquely disposed between the spring fixing part and the spring connection part, and wherein when the first and second operating arms approach each other the spring connection part rotates away from the spring fixing part about a first upper rotary shaft connecting the first operating arm and the first connection arm;
• wherein the strength adjusting part is formed in the spring connection part along the longitudinal direction of the spring connection part and configured to adjust the strength of the spring member by adjusting the position of the other end of the spring member along the longitudinal direction of the spring connection part.
