[0038] As Figure 2 As shown, two folding oar stop levers are respectively active folding oar stop lever 11' and driven folding oar stop lever 11'', and the tail ends of active folding oar stop lever and driven folding oar stop lever are respectively provided with folding oar stop lever gear 116, and the active folding oar stop lever and the driven folding oar stop lever are engaged and driven through folding oar stop lever gear 116, the drive device drives the active folding oar stop lever to rotate, and the driven folding oar stop lever is driven to rotate through the active folding oar stop lever.The drive device drives the active folding oar stop lever to swing in horizontal and vertical interval, and the active folding oar stop lever drives the driven folding oar stop lever to move symmetrically with the active folding oar stop lever through the tooth engagement between the active folding oar stop lever and the driven folding oar stop lever.One folding oar stop lever device and one drive device complete the folding of two pairs of oars simultaneously, which reduces the number of folding oar devices and drive devices, and reduces the time and cost of unmanned aerial vehicle oar folding.
