Background

The prior art timer includes a housing, a rotating shaft, a spring mechanism, and a circuit board. The rotating shaft is connected with the spring mechanism, and when the rotating shaft rotates clockwise by a certain angle, the spring mechanism can drive the rotating shaft to rotate anticlockwise to return to the original point.
