The invention provides an unmanned aerial vehicle stable in starting, and belongs to the technical field of unmanned aerial vehicles. The unmanned aerial vehicle comprises a rack, a mounting plate, two fixed cantilevers, two first movable cantilevers and two second movable cantilevers, a guide cylinder is fixedly arranged on an upper base plate, a first sliding sleeve is rotationally connected to the outer portion of the guide cylinder, a second sliding sleeve is rotationally connected to a lower base plate, the mounting plate is located below the lower base plate, and a driving rod is fixedly arranged on the mounting plate. The driving rod is connected with the guide cylinder through a spline, the driving rod is provided with a spiral guide convex rib I and a spiral guide convex rib II, a spiral groove I matched with the guide convex rib I is formed in the first sliding sleeve, a spiral groove II matched with the guide convex rib II is formed in the second sliding sleeve, and the spiral lead angles of the spiral groove I and the spiral groove II are the same. The spiral directions of the spiral concave I and the spiral groove II are opposite; a first reset spring is arranged between the guide cylinder and the driving rod, and a second reset spring is arranged between the driving rod and the lower base plate. The unmanned aerial vehicle has the advantages of stable starting and the like.
