[0038] The circular tube 17 and the lead screw 18 form the support legs of the base 1. The threaded connection between the circular tube 17 and the lead screw 18 enables height adjustment. The arrangement of the circular tube 17 and the lead screw 18 maintains the installation stability of the device and improves the convenience of the device.

[0039] When using this utility model, the height of the base 1 is adjusted by rotating the lead screw 18. When the electrolytic cell 2 needs to be positioned, the nut 15 is tightened. Then the nut 15 positions the positioning ring 3. Then the water pump 7 is controlled to work, and the liquid in the electrolytic cell 2 enters the interior of the heat exchange tube 4. The water pump 7 drives the liquid in the heat exchange tube 4 to enter the interior of the electrolytic cell 2. The motor 108 is controlled to work. The motor 108 rotates and drives the slide plate 100 to move through the screw 109. This adjusts the movement of the electric push rod 103 on the moving plate 102. The height of the positioning plate 105 and the mounting rod 106 on the crossbar 104 is adjusted by controlling the extension length of the electric push rod 103.
