[0027] The fixing plate 14 is sleeved outside the sliding rod 2 and is arranged to slide up and down. The temperature measuring head at the bottom end of the thermometer 21 and the bottom end of the specimen piece 23 are on the same horizontal line. The bottom end of the thermometer 21 and the specimen piece 23 enter the electrolysis cell 15 synchronously. The temperature of the oxalic acid water during the electrolysis process is monitored through the thermometer 21.

[0028] The holes corresponding to each other between the cathode access terminal 16, the anode access terminal 20 and the power supply output terminal 11 are all used for connecting electrolysis wire harnesses. The cathode access terminal 16 and the anode access terminal 20 are used for externally connecting electrolysis wire harnesses.

[0031] Embodiment 2

[0032] Refer to Figure 5 , and on the basis of Embodiment 1, it is further obtained that the positioning mechanism 13 includes a carriage 25 and a chute 26.

[0033] The carriage 25 is arranged to slide back and forth within the sliding groove 26. The guide rod 27 is arranged to slide through the rear end of the fixed plate 14. The pressure plate 28 is fixedly connected to the guide rod 27. By pressing the pressure plate 28, the guide rod 27 drives the carriage 25 to slide.

[0035] Specifically, by pressing the pressure plate 28, the guide rod 27 drives the carriage 25 to slide, thereby driving the pressing block 30 to slide forward and disengage from the guiding groove 17, facilitating the adjustment of the vertical height of the fixed plate 14. When the pressure plate 28 is released, under the action of the spring 29, the carriage 25 slides backward, driving the pressing block 30 into the guiding groove 17, causing the pressing block 30 to be meshed with the tooth groove 18, and thus fixing the fixed plate 14.

[0036] During the actual operation process, the test sample 23 to be tested is processed into an appropriate size and its surface is cleaned. The electrolytic cell 15 is prepared and cleaned. The electrolytic cell 15 is used to add 10% oxalic acid water as the electrolytic solution, and an electrolytic solution with an appropriate concentration is configured according to specific test requirements;

When the specified electrolysis time is reached, it is displayed in the time display area 5, the electrolysis automatically stops, and the sample 23 is taken out of the electrolytic cell 15;

[0038] During the process of adjusting the height of the fixed plate 14, when making adjustments, hold the fixed plate 14 by hand and press the pressure plate 28, so that the guide rod 27 drives the carriage 25 to slide forward, and drives the pressing block 30 to slide along with it and disengage from the guiding groove 17. Slide the fixed plate 14 up and down to adjust the electrolytic height. After the height adjustment is completed, release the pressure plate 28. The carriage 25 drives the pressing block 30 to automatically slide backward under the action of the spring 29, causing the pressing block 30 to enter the guiding groove 17 and be meshed with the tooth groove 18, thereby fixing the height of the fixed plate 14, facilitating automatic fixation after height adjustment.
