The following image shows a possible design for the arm that will attach to the servo-motor to allow it to rotate, knock the wedge in to release gas, as well as spring back an forth to reduce breakage to the mechanism:

Sketch: focusing on the right hand side of the image - an arm mechanism that will have the abilities as stated above.

Other options for the arm include using only an extension spring as the arm to allow flexibility and force applications. Or solid materials, depending on how the wedge is designed.
