The pin puller based on smart deformable polymers utilizes the variable stiffness and transformation effect of the transformation locking layer to achieve structural locking and release, with advantages such as simple structure, low impact, reusability, and high reliability. The locking state of the locking plate layer is in a straight shape, which can achieve a large axial locking force; After unfolding, it forms an Ω shape and can provide a large release stroke.

The pin puller of smart deormable polymers can be applied to situations such as locking and releasing of spatial deployment mechanisms, separation of satellite and other mechanisms.
