[0033] In this embodiment, when fixing the pipeline 5, the pipeline 5 is passed through the circular groove between the movable sealing block 22 and the fixed sealing block 23, the weld of the pipeline 5 is located between the electrolytic cells 1, and the screw 25 is driven to rotate by rotating the turntable 26. The rotation of the screw 25 can drive the mounting plate 29 to move downward, thereby driving the movable sealing block 22 to move downward, and the assembly block 28 is inserted into the interior of the assembly groove 27. The movable sealing block 22 moves downward to squeeze the pipeline 5 and the fixed sealing block 23 below, so that the movable sealing block 22 and the fixed sealing block 23 can be used to seal the inside of the pipeline 5.

When the electrolyte is pumped out to a height lower than the bottom of the fixed sealing block 23, the pipe 5 can be disassembled and replaced. This method can prevent the electrolyte from leaking when the pipe 5 is disassembled, thereby achieving the effect of convenient replacement of the pipe 5, and the liquid pump 32 is a bidirectional pump. By reversing the motor on the liquid pump 32, the electrolyte in the storage box 31 can be re-introduced into the inside of the electrolytic cell 1, ensuring that the next electrolytic polishing can be carried out normally.
