Abstract
A cart includes a frame body, a tray, a driving mechanism, and a transmission mechanism. The frame body includes a top portion, a bottom portion including a number of castors, and a number of connecting bars between the top portion and the bottom portion, which cooperatively defines a receiving space. The tray is configured to support a workpiece and to be slidably received in the receiving space. The transmission mechanism is connected between the tray and the driving mechanism to transmit the power of the driving mechanism to the tray to drive the tray to move in the receiving space.
