Abstract
The present invention relates to a hand gripper including a first arm, a second arm, a pair of spring members, a first spring member coupling shaft, and a second spring member coupling shaft, wherein a plurality of first elastic force adjusting grooves and a plurality of second elastic force adjusting grooves, to which the first spring member coupling shaft and the second spring member coupling shaft are selectively coupled, respectively, to adjust strength of elastic force provided by the spring members, are formed in a first body of the first arm and a second body of the second arm, respectively.
Claims6
A hand gripper comprising:
- a first arm including a first body and a first grip portion;
- a second arm including a second body and a second grip portion, wherein an upper end portion of the second body is rotatably connected to an upper end portion of the first body;
- a pair of spring members symmetrically provided on front and rear surfaces of the first and second bodies, each of the spring members including a compression spring, first spring supports and second spring supports by which the compression spring interposed therebetween is compressibly supported;
- a first spring member coupling shaft through which the first spring supports are connected to each other and which is supported by the first body;
- and
- a second spring member coupling shaft through which the second spring supports are connected to each other and which is supported by the second body;
- wherein a plurality of first elastic force adjusting grooves and a plurality of second elastic force adjusting grooves, to which the first spring member coupling shaft and the second spring member coupling shaft are selectively coupled, respectively, to adjust strength of elastic force provided by the spring members, are formed in the first body and the second body, respectively.
