Each chain link (1) comprises a chain rod (2), a backplate (3) and anti-skidding teeth (4). The chain rod (2) is of an arc-shaped structure, one end of the chain rod (2) is provided with a groove (5) in a radial direction of a circular arc, and a chain shaft (6) connected at two sides of the groove (5) is provided in the groove (5). The other end of the chain rod (2) is provided with a connector (7) with a width corresponding to the width of the groove (5). The connector (7) is provided with a shaft hole (8) with an axis parallel to the axis of the chain shaft (6). The chain rod (2) is connected to the backplate (3) tangentially to the middle of the chain rod (2) on an outer side of the circular arc. The other side of the backplate (3) that is connected to the chain rod (2) is provided with the multiple anti-skidding teeth (4) in a circumferential direction of the circular arc of the chain rod (2). An appropriate number of the chain links (1) are connected end-to-end according to the size of a wheel, and form, by means of the connection, a chain ring that is mounted in a water drain groove of a tire, and the anti-skidding teeth (4) of the backplate (3) pierce the ice surface under the rolling action of the wheel, thereby improving the friction force of the tire.
