1. A spring loaded actuator assembly comprising:

  • a first member having a set of axially disposed rails;

    a second member configured to translate axially relative to the first member;

    a third member configured for translational movement within the second member, each of the second and third members including;

    a set of teeth configured to engage one another when the third member is moved within the second member, the teeth being defined by a ramped surface; and

    grooves configured to engage the rails of the first member and permit translational movement of the second and third members relative to the first member while preventing rotational movement of the second and third members; and

    a coil spring disposed between the first and second members wherein translational movement of the second member beyond a predetermined axial position causes the teeth of the second member to extend beyond the rails, causing the second member to rotate and the teeth to be retained by the rails of the first member, thereby maintaining the coil spring in a compressed condition while enabling the third member to be freely movable axially.
