Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
A kind of polygonal rotation shape changeable structure, including angle limit plate and T-shaped plate;
The angle limit plate is provided with two pieces, is divided into first angle limiting plate 1 and second angle limiting plate 2, described
The center of one angle limit plate 1 is articulated in the center of the second angle limiting plate 2;
The angle limit plate is provided with the limit point of 3 or 4;
When the limit point is provided with 3, the limit point is the trisection point on the periphery of the angle limit plate,
The T-shaped plate 3 is provided with 6, and 6 T-shaped plates 3 are pivotally connected by the two ends head and the tail of respective transverse bar and form a hexagon
Cyclic structure, as Figure 1-4;
When the limit point is provided with 4, the limit point is the fourth class branch on the periphery of the angle limit plate,
The T-shaped plate 3 is provided with 8, and 8 T-shaped plates 3 are pivotally connected by the two ends head and the tail of respective transverse bar and form an octagon
Cyclic structure;
The vertical bar of the T-shaped plate 3 is located at the inside of the hexagonal annular or octagon ring-type, and the T-shaped plate 3 is pressed
It is numbered clockwise, numbering is that the described T-shaped plate of odd number is a T-shaped plate 31, and numbering is that the described T-shaped plate of even numbers is No. two
T-shaped plate 32;
