Abstract: A hose winder includes a frame, and a hose guiding device which is prefabricated and disposed in a chamber of the frame. The hose guiding device includes a first roller mounted on a first shaft, and a second roller mounted on a second shaft. The first shaft is slidably disposed in a first inclined track. The second shaft is slidably disposed in a second inclined track. The distance between two corresponding points of the two inclined tracks is variable, thereby enabling hoses of various specifications to be reeled out and reeled in between the first roller and the second roller.
