the first pterygoid vein rod (5-1), the second pterygoid vein rod (5-2) and the third pterygoid vein rod (5-3) form a shape matched with the hind wing of the cyrtotrachelus longipedunculatus.
6. The folding wing based on the hind wing folding and unfolding mechanism of the great foot bamboo elephant as claimed in claim 5, characterized in that the anterior radial vein bar (3-1), the posterior medial vein bar (3-2), the additional radial vein bar (3-3) and the posterior radial vein bar (3-4) are assembled with the folding mechanism formed by the second anterior radial vein bar (5-1), the second posterior medial vein bar (5-2) and the second posterior radial vein bar (5-3) in geometric shape with reference to the flight wing of the great foot bamboo elephant, and the wing vein formed by the assembled folding mechanism is the same as the wing vein of the flight wing of the great foot bamboo elephant.
7. The folding wing based on the hind fin folding mechanism of the great foot elephant as claimed in claim 5 or 6,
in the unfolding process of the folding wing, a driving force along the direction of the cylindrical rod is upwards applied to the joint of the hinge frame (2-3) and the cylindrical rod (1-1) to push the connector (2-10) of the second-stage main wing vein rod module (5) to rotate;
wherein, after the linear motion appears on the side pole (1-1), the movable structure who is driven the power trigger includes:
the hinge frame (2-1) and the elastic joint (2-2) are connected for rotation movement;
and, the rotation movement of the hinge mount (2-3) and the connection of the elastic joint (2-4);
and the front radial vein rod (3-1) and the rear middle vein rod (3-2) perform scissors-shaped movement under the connection of the middle hinge frame (2-5) and the middle connector (2-6);
and the additional wing vein rod (3-3) and the back radial vein rod (3-4) perform scissors-shaped movement under the connection of the hinge frame (2-7) and the elastic joint (2-8).
