Patent attributes
A spring-grip easy to adjust grip, comprising a torsional spring and two handles for inserting torsion arms of the torsional spring, wherein spacing blind holes are punched on the torsion arm; the handles comprise a fixed handle, a movable handle, a collar, a spring and a limit steel ball, the fixed handle and the movable handle are both hollow tubular structures, compared to the prior art, the invention is provided with different inner diameter segments in the movable handle to realize the limit steel ball having two states of tension and looseness in truncated-cone through hole, thereby realizing the torsion arm having two states of fixation or movable adjustment in handles, which makes grip adjustment method easier, simultaneously, spacing blind holes are labeled with different grip values, which can intuitively determine the grip when using different spacing blind holes, and scientifically guide the grip exercise.
