Abstract: A gripping force measuring device includes a housing having a pressure detecting device and having a handle portion for being held by a user, a trigger attached to the housing and engaged with the pressure detecting device for applying a pressing force against the pressure detecting device when the trigger is forced toward the pressure detecting device. A displayer may be used for displaying the pressing force applied against the pressure detecting device. The trigger includes an arm having a free end extended out of the housing, and a lever is attached to the housing and includes a free end extended out of the housing for allowing the arm to be gripped and forced toward the lever.

Abstract: A testing device includes a bladder coupled to a pressure gauge, for being squeezed or compressed by users to force air to the pressure gauge, and to measure gripping force of the users. A pumping device may be coupled to the bladder for pumping the bladder to the required pressure. A valve may be coupled between the pumping device and the bladder to control the pumping device. Two pivotal casings may be attached onto the bladder for pressing the bladder, and have flaps to be forced toward each other against the bladder.
