Add the remaining three long plate assemblies 13 sequentially using the same method. Then, insert the connector 14 into the connector 14 positioning and clamping mechanism and connect it to the four long plate assemblies 13. Adjust the position and lock it in place to complete the assembly. Then proceed with the welding work.
