The wall-mounted structure includes a wall-mounted plate fixable on a wall and a connecting plate connectable to an electronic device. The wall-mounted plate includes a plate body and a limiting block on a top end surface of the plate body provided with a first sliding surface extending in an arc shape. The limiting block is provided with a first limiting surface connected to the first sliding surface. The connecting plate includes a limiting plate. The limiting plate is provided with at least a bottom end surface and two main surfaces connected to two sides of the bottom end surface. The bottom end surface is a second sliding surface extending in an arc shape. One of the main surfaces of the limiting plate is a second limiting surface connected to the second sliding surface. The second limiting surface extends from one end of the limiting plate to the other end of the limiting plate.
