Abstract:
    This invention relates to a compound scale spring balance including an elastic component, a supporting sleeve, a pointer block and a scale sleeve, in which, the top of said elastic component is combined to the inside of a top surface of said supporting sleeve, the bottom of the component is combined to said pointer block and a hook for hanging being tested subjects, the inside of the sleeve contains said elastic component, a sub-scale is designed on the pointer block and a main scale is set on said scale sleeve housing the supporting sleeve, the elastic component and the pointer block and is combined to said supporting sleeve by a locating component. The weight of a being tested subject can be measured accurately by the unit scale difference between the main scale of the scale sleeve and the sub-scale of the pointer block and relative displacement.
