The invention discloses a ceiling lamp hook. The ceiling lamp hook comprises a wall-embedded box, a moving plate, a connecting rod, a supporting plate, a hanging plate, a compression spring and magnetic blocks, wherein the supporting plate is a rectangular iron plate, a round hole which is larger than the radius of the connecting rod is formed in the center of the supporting plate and is a connecting rod through hole, and a round screw hole is formed in each of the four corners of the supporting plate. According to the ceiling lamp hook, during installation, the wall-embedded box is embedded into a ceiling, when a ceiling lamp is not hung, under the action of the compression spring and the magnetic blocks, the moving plate drives the hanging plate through the connecting rod, the distance between the hanging plate and the supporting plate is reduced, and therefore the hook and the ceiling are located on the same plane, and attractiveness is not influenced; and a plurality of hooks can be assembled when the house is decorated, so that the situation that the ceiling is damaged because the hook needs to be added when the ceiling lamp needs to be moved or an additional ceiling lamp needs to be arranged is avoided. The ceiling lamp hook has the advantages of being capable of bearing large weight and avoiding limiting the weight of the ceiling lamp.
