録請求の範囲第１項記載の刈払機の安全装置。[Scope of Claim for Utility Model Registration] 1. In a brush cutter in which at least two grips are held in each hand of the operator and the cutting blade is driven by the driving force, the brush cutter performs the cutting work. The brush cutter is characterized in that it is provided with a stop mechanism that stops the driving of the cutting blade when the gripping state of the at least two gripping parts gripped by each hand of the operator during operation is released. Safety device. 2. The stop mechanism includes two stop levers that are held together with each of the two gripping parts during brush cutting work of the brush cutter, and one end that is branched and connected to the two stop levers, and the other end that is connected to the two stop levers. and a wire connected to the fuel valve of the engine which is the driving part, and a wire that drives the cutting blade when both of the two stop levers connected to the fuel valve are released from the grip state. The safety device for a brush cutter according to claim 1, which is a stopping mechanism comprising a spring that biases the fuel valve in a closing direction to stop the fuel valve. 3. The stop mechanism includes two parallel-connected stop switches that are gripped and closed together with each of the two gripping parts during brush cutting work of the brush cutter, and when the gripping states of the gripping parts are both released. The brush cutter according to claim 1, which is a stop mechanism comprising an ignition circuit for an engine serving as a driving unit, which is opened by the two closed stop switches to stop the driving of the cutting blade. safety equipment.
