Described device for measuring force comprises a cantilever bridge-type inductor, a sensor circuit plate and a display screen, and it is electrically connected mutually, and described cantilever bridge-type inductor is fixedlyed connected with one of described elastomer;
Described elastomer locking device comprises a baffle plate, and this baffle plate is angle plate piece always, and the top on its side plate is provided with a step, and its another side plate is provided with two buckles, and described cavity side inwardly is provided with two buckle positions of matching with described buckle; Described cavity side outwardly is provided with the through hole with the elastomer equal number, is provided with the groove of two symmetries in this through hole, and through hole relies on the recess that cavity one end is provided with two symmetries;
Described elastomeric both ends are provided with the projection of two described recess of correspondence respectively; This elastomer passes through hole, projection on its end places in the recess, and described baffle plate side plate props up the elastomer end, and the step on the side plate is stuck on the inboard connecting portion of handle, buckle on another side plate of baffle plate snaps in the buckle position on the described cavity, locks described elastomer;
Described elastomer is sebific duct or adhesive tape, and its quantity is one to five.
The beneficial effects of the utility model are: the utility model is simple and reliable for structure, be convenient to increase and decrease the rubber tube quantity of serving as pulling force rope, can satisfy the user's of different strength levels needs, the utility model can also detect the size of pulling force, makes things convenient for the user to judge whether to reach the purpose of taking exercise according to detected data.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
