The invention discloses a jumping robot of a locust-simulated turning joint lever ejecting mechanism, comprising a front leg with the functions of driving, supporting and shock absorption and a back leg with the functions of driving and turning joint lever elastic energy storage, wherein the front leg comprises a front leg power mechanism, a front leg motor output shaft, an eccentric cam, a frontleg, a front leg spring and the like; and the back leg comprises a back leg power mechanism, a back leg motor output shaft, a shaft coupling, a back leg transmission shaft, a spring, a roller wheel, a back leg, a back leg sliding rotation shaft, a fork-shaped back leg retainer, a fork-shaped back leg retainer tail rod, a spring set, a fixed pull button, a rotary pull button, a screw pair, a sliding guide sleeve, a connecting spring bolt, a steel wire rope, a connecting steel wire rope bolt and the like. With the structural design of the eccentric cam, the front leg has the function of providing engine body promoting force through the elastic energy storage; by adopting the structural design of a movable rotation shaft and a movable pivot lever, the back leg realizes the functions of slow energy storage and rapid energy release in the ejecting mechanism through the combined design of the fixed pull button and the rotary pull button.
