It include s mainly a frame, a cover, a clamp, an elastic member, a gear, a push button, a toggle member and a spring. When the toggle member is pushed, the clamp will hold the phone securely in the frame. The toggle member is pivotally moveable in the opening of the frame. The spring is provided for moving the toggle slantly outside the opening of the frame when external force is absent. When the push button is pressed, the clamp will be moved outwardly to free the phone for fetching and use. All of this m ay be done singlehanded easily. It thus greatly enhances the driving safety when using in a car.
