How do i design this?

Hi


I am pretty new to pro E and for that matter Mechanism design. I am trying to design a mechanism in whish a piston pushes out arms through a cam. The piston is spring loaded. I have attached a hand drawn sketch to explain this. I need help on what connections to use and how to go about designing this.
