The electrode platform is fixed on the Z-axis lifting platform and rises and falls with the Z-axis lifting platform, thereby transmitting the lifting height to other components on the electrode platform. There are densely packed threaded holes on both sides of the electrode platform, which play the role of fixing other parts and fine-tuning the position of parts. The structure of this test platform is very complicated. When connecting the electrode and the test piece, the test piece is clamped by high-temperature resistant fastening screws. There is no way to position the test piece in the smoke oil. Therefore, it is not suitable for columnar ceramic testing of electronic cigarettes. Utility Model Content
