The invention relates to the field of a heating element, and specifically relates to a right-angle silicon molybdenum rod. The right-angle silicon molybdenum rod comprises a first connecting part, a first silicon molybdenum rod, a second silicon molybdenum rod and a second connecting part; the first connecting part adopts a circular disk structure; a first counterbore used for mounting a first screw is formed in the axis position of the first connecting part; a plurality of first mounting holes are formed in the first connecting part around the position of the axis array; the first screw is mounted in the first counterbore; a first connecting hole is formed in the axis position at the upper end of the first silicon molybdenum rod; the lower end of the first screw is embedded in the first connecting hole to enable the first connecting part and the first connecting hole to be detachably connected; the first silicon molybdenum rod and the second silicon molybdenum rod are detachably and perpendicularly connected through a screw thread head; and the second silicon molybdenum rod and the second connecting part are detachably connected through a second screw and a second connecting hole.The right-angle silicon molybdenum rod is creative in structure, convenient to detach, and relatively high in practical value.
