Abstract
A rotor assembly includes a rotation axis, a propeller, an active ring, a driver link, and a reciprocating spring. The propeller includes a hub portion and fan blades. The hub portion is located on one end of the rotation axis, and the inner sidewall of the hub portion has a gear structure surrounding the rotation axis. The active ring sleeves on the rotation axis. The driver link is pivotally connected to the active ring. The reciprocating spring is telescopically disposed on the active ring and abuts against the driver link. When the rotation axis drives the active ring to rotate, the driver link abuts against the gear structure of the hub portion and compresses the reciprocating spring. When the rotation axis stops rotating, the reciprocating spring returns to an initial position to push the driver link to separate from the gear structure.
