The suspension joints and control joints are generally designed separately. For the design of multiple joints of the winglet shaped wing surface, if split joints are used, due to the small size of the airfoil and the small distance between the joints, the connection area between the joint and the winglet is small, not only the connection is difficult, the stress in the connection area is high, but also the joints often cross-interference, resulting in a large structural weight, many connecting parts of the winglet, poor rigidity, large assembly workload, and a long production cycle.

[0008] Preferably, the first mounting surface, the second mounting surface and the third mounting surface form a continuous Z-shaped surface.
