A multifunctional hook comprises hook units. Each hook unit comprises a face plate, a pair of hanging arms and a pair of toothed plates. Each hanging arm is provided with an eccentric axle hole and a swinging axle hole, and swinging axle holes of the two hanging arms of each hook unit are adjacent. Each face plate is provided with a positioning hole and an arc-shaped sliding hole. End faces, opposite to each other, of the same pair of toothed plates are provided with synchronous teeth. Each toothed plate is provided with an axle hole and a moving hole. The toothed plates, the face plates and the hanging arms are connected through swinging shafts sequentially penetrating through the axle holes, the positioning holes and the eccentric axle holes, and sliding shafts transversely penetrating through the arc-shaped sliding holes in the face plates are connected between the moving holes of the toothed plates and the swinging axle holes of the hanging arms. Elastic pieces driving the two toothed plates to rotate and return inwards synchronously are arranged in each hook unit, and therefore articles to be hung and without holes are inserted from positions on the lower portion between the hanging arms and then loosened, and the articles are clamped by the returned hanging arms under the gravity of the articles and action of the elastic pieces. Articles with holes can be directly hung on the hanging arms or clamped and hung like the articles without the holes. Therefore, the multifunctional hook can also hang the articles without the holes besides the articles with the holes. The multifunctional hook is reasonable in structure, easy and convenient to operate, and wide in application range.
