Zusammenfassung:	The utility model provides a combined structure of a sheet metal component and a self-tapping screw. The structure is characterized in that the fixation hole positioned on the sheet metal component is a flanged hole, the flanged hole has the tapered draft angle, and the opening of the flanged hole is pressed on the thread of the self-tapping screw. The combined structure adopts the flanged hole structure and allows the opening of the flanged hole with the tapered draft angle to be directly pressed on the thread of the self-tapping screw, thereby ensuring good self-locking property of the screw, preventing the damage of the thread and preventing the fixed parts from falling. The combined structure of the sheet metal component and the self-tapping screw is simple and easy to apply.
