Because the position of the compression spring chuck 34 is aligned with the bayonet 102, the compression spring 100 can be accurately pressed into the bayonet 102, thereby completing the assembly of the compression spring. Compared with traditional process means, the utility model can not only automatically assemble the compression spring into place, but also significantly improve the assembly efficiency, while effectively saving labor costs, and better meeting the process requirements.
