AI Technical Summary
Existing electric drills adjust the drilling angle solely by the operator changing the tilt angle of the drill bit, resulting in poor accuracy and affecting drilling quality.
The system employs a limiting mechanism and a drilling mechanism. Through the cooperation of a fixed seat, a straight plate, a fixed rod, and a spring, the straight plate is allowed to rotate around the fixed seat and be fixed in the positioning hole to adjust the drilling angle. At the same time, the slide rail and slider structure achieve stable positioning of the drill bit and prevent the drill bit from shifting position.
It improves the drilling accuracy and flexibility of electric drill bits, prevents the drill bit from shifting position during processing, and improves the quality of drilling.
