An energy storage transmission mechanism comprises a transmission shaft (1) and a driving shaft (2). The mechanism is characterized in that the transmission shaft (1) is provided with a slide hole (101); a pair locking bolt (3) is installed in the slide hole (101) and can slide; the upper end surface of the transmission shaft (1) is provided with a track slope groove (102); the inner end surface of the driving shaft (2) is provided with a releasing convex platform (201) corresponding to the track slope groove (102); the upper end surface of the transmission shaft (1) is provided with a lockingconvex platform (103); a positioning shaft (202) which is stretched out of the driving shaft (2) is arranged in the positioning hole (104) of the transmission shaft (1); one end of an energy storagetension spring group (4) is installed on the pair locking bolt (3) and the other end is installed on a driving finger (204) stretched out of the driving shaft (2); and during the rotation process of the driving shaft (2), the driving finger (204) stretches the energy storage tension spring group (4) so that energy storage is performed. In the invention, the structure is simple, reliability is high, through a switch mechanism, the effective power of energy storage and transmission is increased, a mechanism load is reduced, and the motion reliability and the mechanical life of the mechanism areincreased and prolonged.
