C. assembling the workpiece: the rubber gasket is arranged in the locking block, the anode lining is properly bent and deformed until the anode lining can penetrate into the alloy elbow, then the locking block on the anode lining penetrates through the limiting hole of the alloy elbow by using a tool, the locking handle is operated to penetrate the locking pestle through the rectangular through hole of the locking block and then is rotated to complete self-locking of the locking assembly, and finally the deformed anode lining is adjusted to the original shape by using the tool.
