Abstract
A pull pin is configured to lock in a forward position to prevent accidental or undesirable retraction of the pull pin. The pull pin has a housing, a pull pin shaft, an inner shaft, a first and second spring, and at least one ball bearing. The housing has a ball locking space, which holds the ball bearing between the locking space and a ball aperture formed in the pull pin shaft to thereby lock the pull pin shaft in the forward position. Only upon the application of an external force to the inner shaft, which aligns a ball release portion with the ball aperture, can the ball bearing move into the ball release portion and thereby move out of said locking space, allowing for the retraction of the pull pin shaft.
