Power-saving clamping device having a loss-guard function

Abstract

A power-saving clamping device having a loss-guard function has a shell body, a circuit unit and a connection component. The circuit unit is disposed in the shell body to receive signals emitted by an emission component. The circuit unit has an alarm component and a contact switch. The connection component is connected to a portable electronic device. The connection component is also connected to the shell body in a detachable way. The portable electronic device can be clamped onto a user's waistband. When the portable electronic device is separated from the circuit unit by a certain distance, the circuit unit immediately emits light or sounds and alarm, thereby preventing the portable electronic device from being lost or stolen by thieves. When the portable electronic device is connected to the clamping device, the contact switch is touched to turn off the electric unit, hence avoiding waste of electric power.
