Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A mimic horse which can be rocked to and fro and can be moved forward or backward like a tricycle at the same time comprises a simulated animal body mounted on a wheel supporting frame, a steering rod, a set of power mechanisms, and a set of direction changing mechanisms. The direction shift has three stages, forward, neutral and backward, which change the position of pawls of two ratchet mechanisms to make the pawls push the ratchets around for forward or backward motion, or to stay idle without touching the ratchets. The movement of the ratchets is transmitted to the shaft of the rear wheels, which are thereby driven. A child rides on the back of this mimic horse rocking to and fro, and can move the horse forward, backward or can stay stationary without going forward or backward.
