[0024] Further, the number of the lower silver-plated rows 16 is five, and the lower silver-plated rows 16 are vertically arranged at the upper end of the lower frame 2.

[0025] Further, the lower silver-plated rows 16 are used for placing the battery piece, and the design of the silver-plated rows not only provides stable support for the gold wire, but also effectively improves the current conduction capacity due to the material characteristics, reduces the loss in the test process, and places the battery piece on the lower silver-plated row 16. After adjusting the height of the ceramic tube 11, the test gold wire 8 is in parallel contact with the main grid line of the battery piece, forming an effective electrical connection. The battery piece can work normally in this state. At this time, the power supply of the device is started to ensure that the current is smoothly conducted through the gold wire. The test data such as current and voltage of the battery piece can be measured through the external test equipment, and the performance of the battery piece can be evaluated through these data.
