This utility model relates to the field of fastener technology, specifically to a press-to-retract fastener structure, including a mounting box with a cover. The mounting box has symmetrical sliding openings on both sides. A button rod is longitudinally slidable inside the mounting box, with both ends of the button rod passing through the sliding openings on both sides. A retractable rod is laterally slidable inside the mounting box, located below the button rod. One end of the retractable rod is fixedly connected to an insert block. One end of the mounting box has a telescopic opening through which the insert block extends. A transmission mechanism is provided between the button rod and the retractable rod. The button rod drives the retractable rod through the transmission mechanism, causing the locking block to extend and retract. A locking mechanism is provided at one end of the button rod. By assembling the button rod and the retractable rod into a 90-degree retractable component, the size of the fastener is effectively reduced. Furthermore, the locking mechanism prevents the button rod from being pressed towards the sliding opening, reducing accidental unlocking and improving stability during use.
