摘要： A tray assembly includes a base body having a top surface, and a socket member extending downwardly from the top surface and defining a socket hole having a top opening that opens at the top surface.
A resilient member is disposed in the socket hole. A top cover is movably disposed in the socket hole above the resilient member. The top cover is movable upward and downward to switch between a first position and a second position. In the first position, the top cover covers the top opening and is limited from moving downward. In the second position, the top cover is movable downward from the first position, and the resilient member is pressed and stores energy for returning the top cover to the first position.
