Abstract: The present disclosure provides a fan, a holder and a support leg of a holder. The support leg includes a rotational seat; a reinforcing piece where one end of the reinforcing piece inserted into the rotational seat and the reinforcing piece is bendable; and a soft leg sleeve sleeved on the reinforcing piece. The reinforcing piece and the rotational seat of the support leg are integrally formed to ensure more stable connection; the assembly of the support leg can be completed simply by sleeving the leg sleeve on the reinforcing piece. In addition to normal supporting effect, the support leg can also be held by hand or wound on another support piece based on different scenarios, bringing flexible and rich functions.
