[0026] Working principle: A pressing jig is a tool that applies pressure and maintains the position of a workpiece during the manufacturing and assembly process. Its main function is to ensure that the workpiece can be accurately moved to the desired position and subjected to the required pressure during the assembly or processing process, so as to promote a firm connection between the workpieces.
