Abstract:
1. A saw cover safety sensing device comprising: a protecting cover; a sensing controller at one side of the protecting cover; a control circuit within the sensing controller; the control circuit serving for receiving electric static signals from a human body and emitting control signals; the sensing controller further comprising a power switch, at least one batteries, a plurality of LED) lights and a transparent cover; at least one signal sensing wire connected to the sensing controller; each signal sensing wire having a metal foil sheet; one surface of the metal foil sheet being coated with glue so that the metal foil sheets and the signal sensing wires are adhered to two sides of the protecting cover; the signal sensing wires and the metal foil sheets having a function of transmitting electric static signals of human body to the sensing controller; the at least one signal sensing wire and at least one metal foil sheets having function of expanding sensing area so as to detect electric static signals emitted from a human body; and a buzzer connected to the sensing controller; the buzzer buzzes in response to electric static signals.
