[0002] Impact drills are drilling tools that use electricity as power. They are common products among power tools and are also the most in-demand power tool products. Impact drills have a rotating mode and are particularly suitable for drilling holes in materials that require less force, such as cork, metal, bricks, and tiles. Impact drills simply rely on the motor to drive the transmission gear to increase the force of the drill bit to rotate, so that the drill bit can scrape and penetrate metal, wood, and other materials. The existing impact drill structure design is complex, the production cost is high, and there is still room for optimization. Utility Model Content
