Abstract: A phone cradle having a locking module for a vehicle is provided. The locking module includes a base frame having first, second and third compartments, supporters at opposite positions, and a fixing portion extending downwardly. A locker key configured for movement along an axis thereof is placed in the third compartment and wound with a key spring. An ejector cam is movably fixed to the lower surface of the base frame and includes a hinge hole at one end, an erect pressed plate at another end configured to interlock with the locker key, a pressing portion perpendicular to the pressed plate at a third end, and a guide hole for radially moving the ejector cam a limited degree with respect to the hinge hole. A locker is movably fixed to the supporters and operatively associated with the locker key to receive a force via the pressing portion of the ejector cam upon movement of the locker key along the axis thereof.
