A deformable support frame, comprising a body (3) and an adapting portion. The body (3) is a bendable and deformable hollow pipe structure provided with multiple air nozzles (31) on a side wall thereof; and the adapting portion comprises an elastic adapter (1) used for being sleeved on the air outlet of a blower and an air duct (2) connected to the body (3). When using, the body (3) is firstly bended into a desired shape according to requirements; then clothes to be dried are hung on the body (3); then the elastic adapter (1) is mounted on the air outlet of the blower; the blower is turned on to blow hot air; the hot air is transmitted to the body (3) by means of the air duct (2); and finally the hot air is blown onto to the clothes through the air nozzles (31). Under the constant blowing of the hot air, the clothes may be dried quickly, even in a rainy day or during the journey, thus the need of drying clothes of a user is met. Due to the use of external hot air, the deformable support frame has advantages such as low cost.
