AI Technical Summary
The existing mini tillers have complex throttle and kill switch structures, making them inconvenient to operate. The kill circuit design is also complex and has a high failure rate.
It adopts a structure with a built-in kill wire and conductive plate in the throttle handle. The throttle handle can be rotated to control the engine kill and throttle level. Combined with conductive bracket and elastic element to improve contact stability, it can be easily installed and removed by a knob switch.
It achieves a simple and easy-to-operate flameout control, improves the stability and service life of the flameout circuit, and reduces the failure rate.
