The invention discloses a rotor connecting device of a quad-rotor unmanned aerial vehicle, which comprises a driving shaft, wherein the top of the driving shaft is fixed with the bottom of a connecting block. The device has the beneficial effects when the height of a rotor needs to be reduced, a second pipe is rotated, a first external thread block is enabled to be separated from a first threadedgroove in a first pipe, a handle is lifted, the handle drives a movable groove to ascend through a U-shaped block and a movable shaft, a spring is compressed, each T-shaped column is pulled out from an corresponding slot, the handle is gripped and rotated, a third external thread block is enabled to be separated from the first threaded groove in the second pipe; an outer pipe is enabled to be separated from first threaded teeth of the outer wall of the second pipe; a second threaded groove in the outer pipe is in threaded connection with the first threaded teeth in the first pipe; the third external threaded block is in threaded connection with the first threaded groove in the first pipe; the handle is loosened, the spring stretches and abuts against the bottom of the T-shaped column to beinserted into the slot from the interior of the insertion hole, and the stability of the connected outer pipe is improved through insertion of the T-shaped column and a top cover to the outer pipe.

    本发明公开了一种四旋翼无人飞行器的旋翼连接装置,包括驱动轴,驱动轴顶部与连接块的底部固定,本发明的有益效果:当需要降低旋翼的高度时,旋转二号管,使一号外螺纹块与一号管内的一号螺槽分离,提拉把手,把手通过U型块和活动轴带动活动槽上升,从而弹簧压缩,每个T型柱从插槽内抽出后,进而握住把手并旋转,使三号外螺纹块与二号管上的一号螺槽分离,将外管与二号管外壁的一号螺齿分离,再通过外管内部的二号螺槽与一号管内的一号螺齿螺纹连接,将三号外螺纹块与一号管内的一号螺槽螺纹连接,松开把手,弹簧伸长,顶住T型柱的底部由插孔内部插入插槽内部,通过其插入,以及顶盖对外管,使外管连接后的稳定性得到了增加。
