The mounting plate 502 can also be pried open and rotated at the connecting rod 501 so that the mounting plate 502 and the threaded portion 2 are at a 90-degree angle. At the same time, the fixing block 504 and the clamping block 6 on the mounting plate 502 are disengaged from the clamping groove 4 on the outer wall of the threaded portion 2, and the threaded portion 2 is inserted into the installation position of the external high-temperature alloy heating furnace.

[0028] Welding stage

[0029] Insert the resistance wire into the interior of the insertion port 11, and weld the exposed parts of the insertion port 11 and the resistance wire at the welding groove 3 to increase the welding area between the resistance wire and the insertion port 11, making the connection between the resistance wire and the main rod body 1 more firm.
