[0002] Nuts are commonly used spare parts for fasteners, with large quantities and wide applications. For example, hexagonal heads, decagonal nuts, and twelve-pointer nuts with flanges are widely used in aviation and aerospace engines. In the tapping process, the existing technology usually uses a vise or a lathe to clamp the hexagonal head, decagonal head or twelve-pointer head of the fastener for tapping. The products processed by the existing clamping method are inefficient and easily clamp the fasteners, resulting in excessive verticality, which leads to product scrapping. Summary of the invention
