An elastic acting force structure of a furniture upturning device comprises a fixing support, a swing rod and a spring assembly, wherein the swing rod is arranged on the fixing support in a swinging mode and interact with the spring assembly during swinging, so that the spring assembly generates elastic acting force; the spring assembly comprises a front connection part, a rear connection part, a guide shaft and a spring; the guide shaft is sleeved with the spring; the two ends of the spring elastically act on the front connection part and the rear connection part; the two ends of the guide shaft are connected with one end of the front connection part and one end of the rear connection part in a matched mode; the other end of the front connection part is connected with the swing rod in a matched mode; and the other end of the rear connection part is connected with the fixing support in a matched mode. By improvement of the structure, the elastic acting force structure of the furniture upturning device has the characteristics of being simple and reasonable in structure, safe, reliable, easy to produce and achieve, rapid to adjust, convenient to operate, long in service life, smooth in opening and closing process, capable of saving labor, low in collision, low in noise, wide in use range and the like, and practicability is high.
