The invention relates to a wind-proof clotheshorse comprising hangers, small bars with magnetic sheets, telescopic small plates containing magnetic sheets at the tail ends of the telescopic small plates, a spring and the magnetic sheets, the small bars with the magnetic sheets and the magnetic sheets are arranged below the hangers, and the telescopic small plates are respectively embedded at both sides of the neck of the clotheshorse; and moreover, the two telescopic small plates are connected by the spring arranged in a hole at the neck of the clotheshorse. After the hangers are hung on a clothesline, the small bars with the magnetic sheets and the magnetic sheets are sucked for preventing the clotheshorse from falling off; and the two telescopic small plates which contain the magnetic sheets at the tail ends of the telescopic small plates and are embedded at the neck of the clotheshorse are pulled out, are elongated and are also sucked at both sides of the clothesline or are directly sucked on an iron pipe of the telescopic iron clotheshorse for preventing the clotheshorse from moving. Therefore, the wind-proof clotheshorse disclosed by the invention can be widely utilized in families for airing clothing, and the unnecessary trouble caused by the phenomena of falling off, being contacted with dirt or collision and coloration between the clothing are avoided, so that the life is more convenient and nicer.
