Chaos pendulum presentation device of three leaves

The utility model relates to a chaos pendulum presentation device of three leaves. The utility model discloses a support, around self axis pivoted owner rotation axis, fix on main rotation axis along with the first vane of the synchronous pivoted of main rotation axis, install on main rotation axis the second vane around main rotation axis free rotation, main rotation axis pass through the bearing frame install in on the support, second vane blade surface be fixed with keep away from main rotation axis and with main rotation axis parallel arrangement's auxiliary rotating axle, epaxial the installing of auxiliary rotating can be around the third vane of auxiliary rotating axle free rotation. Main rotation axis is by after the drive is rotated in the twinkling of an eye, the rotation direction of first vane, second vane, third vane is irregular chaos swing, and visitor or learner can clearly watch the chaos chaotic phenomenon that the mechanism demonstrates that puts to the more audio -visual chaotic phenomenon
