The electrode is deformed and further affects the use accuracy of the electrode. Figure 1 is a current electrode fixture, wherein the electrode clamping hole 11 and the electrode locking hole 12 have an intersection inside the fixture. For locking, the bolt directly acts on the electrode. In the process of locking the electrode, because the end of the bolt is relatively sharp, it is easy to scratch the electrode.
