[0042] When the present application is in use: first, the metal screw 3 in the insulating structure is sleeved onto the insulating plate 5, and the threaded end of the metal screw 3 is inserted through the through hole 2 in the electrode boiler 1, and the protrusion 9 located in the center of the linkage block 11 in the inner insulating fixing block 6 is inserted into the groove 8 of the metal screw 3.
