[0012] The beneficial effects of the present invention are as follows: 1. By pressing the switch, the connecting rod in the drawer is pressed, so that the movable plate on the connecting rod moves to the right, and the cross bar rises in the slide groove, thereby driving the telescopic plate to move upward, so as to close the drawer;

[0013] Second: The connecting rod on the push switch is pulled out through the pull ring, so that the movable plate on the connecting rod moves to the left, and the movable plate is lowered in the slide slot through the cross bar, thereby driving the telescopic plate to move downward, so as to open the drawer;

[0014] Third: The movement trajectories of the telescopic plate and the movable plate are limited respectively by the opening on the extension plate; the activity space of the cross bar is increased by the opening groove, and the fixing nuts are set to fix the two ends of the cross bar and limit them in the slide groove; the raised strip is installed on the cabinet body, and the raised strip and the groove strip are matched when the drawer is closed, so that the drawer is closed more closely; the reset spring is used to assist the pull ring to reset the push switch;

[0015] The invention adopts a pull ring, a push switch, a connecting rod, a movable plate, a sliding groove and a cross bar to control the opening and closing of the telescopic plate to the drawer, thereby greatly improving the quality of the equipment and the safety of use.
