description The invention belongs to the technical field of functional macromolecule and experimental mechanics, and provides a gripping device for testing pull-power property of low intensity hydrogel. The device includes a dumbbell shaped mould, a gripping device A applied to a reciprocally moving testing machine and accessories thereof, or includes a dumbbell shaped mould, a gripping device B applied to a reciprocally moving testing machine and accessories thereof; different gripping devices correspond to different accessories. The reciprocally moving testing machine applies static, dynamic load to hydrogel samples, and finishes curve measurement for power and displacement. The present invention has the effects and benefits that the pull provided by the gripping device when pulling to the gripping head of hydrogel samples, replaces in the original method the adhesive force of using glue, whose main component is cyanoacrylate, to stick the hydrogel sample on the gripping device. The present invention enhances the measu
