[0034] The first connecting section 240 is fixedly clamped in the pot opening 221, one end of the first connecting section 240 is rotationally connected with a second connecting section 241, and a first pin shaft 242 is inserted between the first connecting section 240 and the second connecting section 241 for rotational connection; the third connecting section 250 is rotationally connected to one end of the second connecting section 241, a second pin shaft 251 is inserted between the third connecting section 250 and the second connecting section 241 for rotational connection, the bottom of the third connecting section 250 is fixedly connected with a sliding rail 252, and the third connecting section 250 is slidingly connected with the notch 150 through the sliding rail 252; a plurality of heating coils 260 are fixedly connected outside the third connecting section 250, and the plurality of heating coils 260 surround the second connecting section 241 to continuously heat the molten liquid flowing inside.
