【Specific embodiment】
Refering to Fig. 1, Fig. 2, the pneumatic operation of landing gear of unmanned plane of the present invention, including wheel 1, first connecting rod 2, second connecting rod 3,
Third connecting rod 5, cylinder 4, valve 6, servo motor 7, the valve 6 control the air inflow of cylinder 4, and the servo motor 7 controls cylinder 4
Movement, the second connecting rod 3 and 5 movable connection of third connecting rod, the cylinder 4 and 2 movable connection of first connecting rod, cylinder
4 consolidate with 3 movable connection of second connecting rod, the wheel 1 and 2 movable connection of first connecting rod, the third connecting rod 5 with unmanned plane
Fixed connection, the third connecting rod 5 are provided with third guide post 51, third guide post 51 and 3 movable connection of second connecting rod, and described first
Connecting rod 2 is provided with linkage section 22,21 and first guide post 24 of support end, and the second guide post 23, the second guide post are provided on linkage section 22
23 can live with 3 movable connection of second connecting rod, the second guide post 23 and 4 movable connection of cylinder, the first guide post 24 with first connecting rod 2
Dynamic connection, the second connecting rod 3 offer stroke groove 31, and the width of stroke groove 31 is equal to the diameter of the second guide post 23, stroke groove
