description The utility model relates to a heating element tool for an optical glass rod drawing machine. Belongs to the technical field of bar drawing forming. The heating element fixing tool mainly solves the problems that due to the fixing mode of an existing heating element fixing tool, the service life of a heating element is short, frequent replacement consumes high cost, and the structure of the tool is unstable. The softening furnace is mainly characterized by comprising a softening furnace hearth, and the hearth of the softening furnace is provided with a spiral groove and a temperature measuring element fixing hole. The stress state of the heating element in the working process is changed in the mode that the heating element is fixed through the spiral groove, the temperature measuring element fixing hole with a certain wall thickness is provided so that the purposes of prolonging the service life of the heating element and improving the structural strength of a hearth of the softening furnace can be achieved,
