[0002] In the field of electrical installation, a large number of wire crimping nails are used to fix different cables to each other. The wire crimping nails are mainly composed of a pressing frame and nails. In order to improve the assembly efficiency, it is often necessary to insert the heads of the nails into the pressing frame in advance. In this way, at the installation site, the operators can directly use the assembled wire crimping nails to quickly complete the assembly without the need to assemble the wire crimping nails on site. However, in the current production process, the nails need to be made in advance and then inserted into the pressing frame through special nail pressing equipment. The two-step process will reduce production efficiency. Summary of the invention
