Abstract
The utility model provides a USB interface switching device mainly including a shell, a USB plug and a USB socket. The USB interface switching device is characterized in that pins of the USB plug are connected with pins of the USB socket correspondingly; an electric magnet is disposed in the shell and the electric magnet is connected with the USB plug electrically; a bell is fixed on the shell; and an elastic driving hammer is provided with an end fixed on the shell. When the USB plug is connected with a power source, the elastic driving hammer is attracted by the electric magnet through electromagnetic forces, so that the elastic deformation of the driving hammer is generated and the driving hammer gets far away from the bell and elastic potential energy is accumulated. The elastic driving hammer loses attraction caused by the electromagnetic forces of the electric magnet and releases the elastic potential energy in a moment when the USB plug is disconnecting with the power source, so that the elastic driving hammer hits the bell and the bell rings. When a user turns off a computer, power supply of the USB interface switching device is cut off, and the bell arranged in the USB interface switching device rings clearly to prompt the user to unplug and take away a portable storage device.
