Supporting leg and single crystal furnace heater with same

The utility model relates to the technical field of single crystal production equipment, and provides a supporting leg and a single crystal furnace heater with the supporting leg. The foot plate and the vertical plate are integrally formed to form an L-shaped structure; the two sides of the lower portion of the vertical plate are narrowed inwards in an arc transition mode and are flush with the front side face and the rear side face of the foot plate. The lower part of the vertical plate is narrowed inwards, the foot plate is narrowed along with the vertical plate, and the resistance is reduced, so that the heat generated by the part far away from the quartz crucible is greatly reduced, the heat radiation to the quartz crucible is reduced, the reaction between silicon liquid and the bottom of the quartz crucible is reduced, the content of oxides such as SiO is reduced, and finally the content of oxygen impurities in a silicon single crystal rod is reduced; according to the utility model, the structure is simp
