一种可调速电推剪
The motor speed is controlled by a toggle switch, and the stepless speed adjustment of the electric clipper is achieved by using a grating sensor and a contact switch. This solves the problem that existing electric clippers cannot steplessly adjust the speed, and improves the adjustment accuracy and performance.

AI Technical Summary
Existing electric clippers cannot steplessly adjust the motor's operating speed, resulting in low adjustment accuracy.
The motor speed is controlled by a toggle switch. By toggling the toggle switch, the blades rotate within the grating sensor, achieving stepless adjustment of the motor speed. The grating sensor and contact switch work together to transmit signals to the circuit board for speed regulation.
It achieves stepless adjustment of motor speed, is easy to operate, and has better performance.
