Abstract
An arm connection structure for connecting an arm to a body provided in the present invention includes: a connection shaft, a shaft sleeve that can be sleeved on the connection shaft in a manner of rotating relative to the connection shaft, and an elastic member sleeved on the connection shaft. The shaft sleeve is provided with a curved guide slot extending along a peripheral direction of the shaft sleeve, and the connection shaft is provided with a guide block that matches the curved guide slot and that can slide in the curved guide slot. The curved guide slot has a first lock position for locking the arm in an unfolded state, and a second lock position for locking the arm in a folded state. The present invention can make the arm not easily shake in a flight process of an unmanned aerial vehicle, making flight more stable.
