Abstract
A swinging structure for a mechanical animal includes a housing and a shell. The housing has disposed therein a shaft and a rod. The shaft has an eccentric wheel and a worm gear mounted thereon. The rod is provided with a worm that engages the worm gear. The outer wall of the shaft is provided with at least one post. These posts are fitted with a T-shaped actuated plate. The end of the actuated plate that is connected to the posts is provided with an elongated groove. The opposite end thereof is provided with a pin. The other side of the elongated groove is provided with a notch that can just accommodate the outer edge of the eccentric wheel. The shell is provided with an actuated rod corresponding to the pin. When the eccentric wheel rotates, due to the notch that moves along the outer edge of the eccentric wheel, the actuated plate can oscillate within the elongated groove thereof, and the pin thereon can actuate the actuated rod to cause the shell to oscillate.
