Abstract
The automatic locking and releasing structure for a push-pull plug of this invention includes an upper case, a bottom case, a slider and push-buttons. The bottom case is suspended therein with two symmetrically arranged slide tracks that are each provided at the inside thereof with a wedge piece. The opposing sides of the slider are each formed with a resilient retaining arm, and the slider is movably provided between the two slide tracks. The free ends of the resilient retaining arms are movably attached to the push-buttons provided at the outside of the slide tracks. As such, when one manipulates the push-buttons to move along slide slots formed in the upper case and bottom case, the slider may be retracted or extended at the same time thereby subjecting the resilient retaining arms to assume a locking or releasing state with respect to the wedge pieces.
