The utility model discloses an optical fiber wire drawing furnace which comprise a furnace top air disc, a furnace body, a middle sleeve, a heat preservation body, a heating body and an extending pipe. The extending pipe is an extending pipe device formed by connecting segmented branch pipes with one another. An air tightness device is fixedly connected to the lower surface of the furnace body. The extending pipe device is arranged at the lower end of the air tightness device. An elastic device is further fixedly connected to the upper end of the extending pipe device. Due to the fact that a limiting switch is fixedly connected below the air tightness device, when connected with the air tightness device, the elastic device can be stopped in time when passing the position. The optical fiber wire drawing furnace has the advantages of being low in manufacturing cost, simple in structure, free of complicated later maintenance work, long in service life and the like.
