Hunching strong support and elastic back-jacking chest-outing posture correction function combination bracing

The invention relates to a hunching strong support and an elastic back-jacking chest-outing posture correction function combination bracing. The bracing comprises a reversed bent plate, an upper edge,a lower edge, an auxiliary belt, waist belts, a lumbar pad, a strong upright plate and a waist pad; the reversed bent plate is an elastic plate, the part close to the lower end of the strong uprightplate is an arc-shaped protruding surface fitting a normal physiological curvature, spring bolts are arranged on the reversed bent plate and the strong upright plate, universal clamping grooves and lock mouths are formed in the upper edge and the lower edge, the width between a left chest strap and a right chest strap is transversely supported by the upper edge, the width between a left waist beltand right waist belt is supported by the lower edge to reduce centripetal force on two sides, meanwhile lever acting force can be transversely performed by the upper edge and the lower edge to improve using of the reversed ben
