[0002] A pot lid is a common kitchen appliance. Its primary function is to maintain the temperature of the contents and prevent splashing and steam from escaping due to heat. A pot lid typically consists of a lid body and a handle, which is attached to the top of the lid body via screws and other accessories.

[0003] When assembling the pot lid, it is necessary to first pass the screw through the gasket, then put on the bushing, and finally pass the connecting end of the screw through the center hole of the pot lid body and screw it together with the handle; the existing pot lid assembly is usually assembled and processed step by step by manual labor. This processing method has a low degree of automation and low work efficiency. It is not only time-consuming and labor-intensive but also has very low production capacity. The assembly efficiency often cannot meet the needs of the factory; in addition, manual assembly is prone to incomplete assembly, which may cause the handle to fall off. Summary of the Invention
