When the electrode clamping frame 7 completes the clamping and fixing of the dummy electrode 8, the electrode clamping frame 7 and the dummy electrode 8 are pulled upward by the conductive copper material rod 6, and the weight of the dummy electrode 8 is weighed by the weighing sensor 33, and the obtained weighing data is transmitted to the external computer in real time;

[0017] A weighing anti-shake frame 34 is fixedly assembled between the upper connecting flange 31 and the lower connecting flange 32.
