The telescopic link group includes: a plurality of telescopic rods 13; the plurality of telescopic rods 13 are uniformly arranged on the telescopic rod supporting frame 12 of the flying wing main board at intervals along the width direction; the fixed end of the telescopic rod 13 is fixedly connected with the telescopic rod supporting frame 12, and the axial direction of the telescopic rod 13 is along the longitudinal direction of the wing 2. And the telescopic rod 13 is a multi-stage telescopic rod, so that multi-stage telescopic can be realized. As shown in fig. 2 and 3, in this example, three telescopic rods 13 are respectively disposed on the left and right sides of the telescopic rod support frame 12 in the same plane, and the telescopic rods 13 are three-stage telescopic rods.
The wing 2 on each side is respectively connected with each telescopic rod 13 in the telescopic rod group on the same side, and the wing 2 is driven to stretch and retract through the synchronous stretching of each telescopic rod 13 in the telescopic rod group so as to realize the adjustment of the wingspan area of the wing 2; and the multi-stage telescopic function of the telescopic rod 13 is utilized, so that the multi-stage adjustable span area can be realized.
In order to realize synchronous extension and retraction of each telescopic rod 13 in the telescopic rod groups at the left side and the right side, in this example, the telescopic rods 13 are telescopic rods 13 with traction ropes as shown in fig. 4; the telescopic rod support frame 12 is provided with an electric reel 15 and a control unit 33 for controlling the electric reel 15; the telescopic rod 13 comprises a multi-stage telescopic rod body 17, a telescopic rod head fixing ring 20 arranged on the rod head of each stage of telescopic rod body, and a telescopic rod inner traction rope 14 arranged inside the telescopic rod; the telescopic rod 13 realizes a step-by-step telescopic function through the multi-stage telescopic rod body 17 and provides a certain bending moment and tensile strength.
