When the slide rail is pushed in the direction of the slide, the hook end The inclined surface of the hook end that protrudes laterally will first touch the positioning pin located in the notch of the guide groove.

The positioning pin is pushed out of the notch by the inclined surface and enters the hook groove of the lock hook along the inclined surface, and the slider springs to the end along the longitudinal guide groove under the action of the return spring.

At the same time, the positioning pin that enters the lock hook also drives the lock hook and the pull-out slide rail to spring to the tail end of the guide groove together, which enables the drawer installed on the pull-out slide rail to be locked in the drawer relatively stably under the action of the return spring Position; when the slide rail is pulled outward, the lock hook drives the positioning pin to move toward the front end of the guide groove, and the return spring is elongated.

As it reaches the top, the hook end of the lock hook that continues to move outward pushes the positioning pin into the top of the guide groove The notch recessed to the side repositions the slide in that position, while the pull-out slide that has disengaged from the positioning pin continues to go out and pulls the drawer out.
