[0002] Components used in aerospace electronic and electrical products usually have certain forming technology requirements for their lead ends. For example, the aerospace industry standards require that the leads at both ends of axial components be bent to avoid damage to the component body or leads and to provide stress relief. The aerospace industry standards also require that special forming tools be used to form the leads of axial components.

[0003] At present, traditional lead bending tools used for axial components can only hold one axial component of the same model at a time, and can only bend the leads of one axial component at a time. This is not only inefficient, but also the bending position is fixed when using traditional tools to bend the leads. It is impossible to adjust and select the bending point according to the pad spacing of different printed circuit boards, which is inconvenient to use. After being soldered to the printed circuit board, it cannot eliminate stress and may eventually cause the leads to break. Summary of the invention
