Undergrad What force is needed to collapse this spring-loaded pair of arms?

Hello .
The goal is to look for what force F I need to apply in order to return the arms to the closed position. Attached is a schema in the hope that my purpose will be understood
I want to know what forces are acting on the system of the arms as well as the springs
Many thanks in advance

Can you say what the function of the two hinged arms is? What is this used for?

Arm release: The system release is like an awning to the sun that has arms.
When the awning opens the arm opens and because the spring is stretched the arm tends to open. And when I want to return the awning to the closing position with the help of the spring force the arms are returned to their original place
I added again the agreement in which there is the spring in all three modes
Thank you very much for your reference. Daniel
