Grasper actuated by plunger

I'm Looking to improve design of a spring alligator clip that is actuated by plunger or a push or pull method. These are the type of alligator clip I want to actuate via push or pull plunger stlye https://www.google.com/aclk?sa=l&ai=DChcSEwiLjpLRweSGAxViRP8BHRNSD4gYABALGgJtZA&gclid=Cj0KCQjwvb-zBhCmARIsAAfUI2t8vB2lvE-VMQa7fYyznn1-8_e6_50GfEZRVtfMM_CXG84w4ZRvcFwaAvCMEALw_wcB&sph=&sig=AOD64_2CQg5m4HJczvXEheVKhTmGJVXSxw&ctype=46&q=&ved=2ahUKEwj6v4vRweSGAxUCkokEHZwGBmUQzzkoAHoECAMQFg&adurl=.
