Portable Manual Siren Super Loud Aluminum Alloy For Forest

Features:

The manual alarm provides power and sends out alarm signal by shaking the handle. The sound size depends on the shaking speed of the handle. The shutter mechanism of baffle is set in the sound window to select the sound strength and strength signal. The sound window is quickly closed to block the sound and generate different signals.

The handle is connected with the driving shaft of the gear increasing mechanism, the output shaft of the gear increasing mechanism is connected with the clutch slider through a pin, and the clutch slide block is connected with the flange friction transmission of the impeller. Its purpose is to provide power through shaking the handle to send out alarm signal without power supply support. The sound level depends on the hand rolling speed.
