ABSTRACT:
An exercising handgrip includes a first handle, a second handle pivotally connected with the first handle, a damping spring biased between the first handle and the second handle, a threaded adjusting module movably mounted on the second handle and pressing the damping spring, and a threaded adjusting knob rotatably mounted on the second handle and screwed onto the threaded adjusting module to move the threaded adjusting module relative to the damping spring by rotation of the adjusting knob. Thus, the adjusting knob is rotated on the second handle to drive the threaded adjusting module to move forward or backward relative to the second handle so as to change the distance between the first handle and the second handle and to compress or extend the damping spring, thereby adjusting the damping force of the damping spring.
