- a second return spring connected between said second and fourth spring holders for biasing said second lever in said closed position;
- a first hinge pin having a first end extending through a first one of said hinge pin holes in said upper side wall and into a first one of said catch grooves, and a second end in contact with a first surface portion of said first cam;
- a second hinge pin having a first end extending through a second one of said hinge pin holes in said upper side wall and into a second one of said catch grooves, and a second end in contact with a first surface portion of said second cam;
- a third hinge pin having a first end extending through a first one of said hinge pin holes in said lower side wall and into a third one of said catch grooves, and a second end in contact with a second surface portion of said first cam;
- a fourth hinge pin having a first end extending through a second one of said hinge pin holes in said lower side wall and into a fourth one of said catch grooves, and a second end in contact with a second surface portion of said second cam;
- a first stop pin diametrically extending through said first hinge pin;
- a second stop pin diametrically extending through said second hinge pin;
- a third stop pin diametrically extending through said third hinge pin;
- a fourth stop pin diametrically extending through said fourth hinge pin;
- a first spring positioned over said first hinge pin and in contact with said first stop pin and one of said tabs extending horizontally from said left side wall for biasing said first hinge pin downward;
- a second spring positioned over said second hinge pin and in contact with said second stop pin and one of said tabs extending horizontally from said right side wall for biasing said second hinge pin downward;
- a third spring positioned over said third hinge pin and in contact with said third stop pin and another one of said tabs extending horizontally from said left side wall for biasing said third hinge pin upward;
- and
- a fourth spring positioned over said fourth hinge pin and in contact with said fourth stop pin and another one of said tabs extending horizontally from said right side wall for biasing said fourth hinge pin upward.
