when the solar wing is tightly pressed and restrained on the star body, as shown in fig. 3 and 4, the hinged seat 8 is close to the second end seat 6, the driving pressure spring 9 is compressed, and elastic energy is stored. The mounting surfaces of the female mounting seat 1 and the male mounting seat 2 are parallel, and the connecting rod 10 is approximately parallel to the female mounting seat 1. And the locking compression spring 11 is also in a compressed state in the state, and the locking ejector rod 4 is pressed against the end surface, close to the first end of the female mounting seat 1, in the compression spring cap 13.
When the solar wing needs to be unfolded, the constraint on the solar wing is released, the elastic force of the driving pressure spring 9 is released, the driving pressure spring 9 extends to drive the hinged seat 8 to slide towards the first end seat 5, and the hinged seat 8 drives the male mounting seat 2 to rotate through the transmission of the connecting rod 10.
