How to name the latest item of forge【1.12.2】

Today I am learning how to create an item in forge

But I have some small problems when naming item

His name has always been

item.ITEM_ Name (set with settranslationkey (name).Name)

Like my Genshin_ stone

Then his name is item.genshin_ stone.name

There is no problem with the texture

//itemBase class
public class ItemBase extends Item implements IHasModel {
    private Item item = new Item();
    public ItemBase(String name, CreativeTabs tab, int maxStackSize){
        //setUnlocalizedName(name);
//        this.setTranslationKey(name);
        this.setMaxStackSize(maxStackSize);
        this.setTranslationKey(name);
        this.setRegistryName(name);
        this.setCreativeTab(tab);
        ModItems.ITEMS.add(this);
    };
    @Override
    public void registerModels(){
        cn.lmfans.genshin.genshin.proxy.ClientProxy.registerItemRenderer(this, 0, "inventory");
//        genshin.CommonProxy.registerItemRenderer(this, 0, "inventory");
    }

}

//ModItems class
public class ModItems {
    public static final List<Item> ITEMS = new ArrayList<Item>();

    public static final Item GENSHIN_STONE = new ItemBase("genshin_stone", CreativeTabs.MATERIALS,160);
//    public static final Item genshinStone = new Item();
}

Please teach me how to solve this problem. He has stuck me for several days
