Hand-crank siren does not require a power source, and can provide an effective I places without power support. By manually rotating the crank, it is accelerated step by step through the transmission of the gear box, and then t driven to run at high speed through the transmission block. In the process of high-speed operation of the ringing wheel,the absorbed pressure resonance, which is simultaneously extruded to the fixed window of the fixed wheel, thereby acting as an alarm.Hand-crank siren is small in size,light in weight, easy to carry and install and does not require any tools. It only needs an area of 0.15 square meters and a place where people stand to operate normally, and the mobile operation is very strong.
