Its longitudinal width and needle plate width are large, which not only occupies a large space, but also may cause the overall structure of the flat knitting machine to be bloated, which is not conducive to miniaturization and compact design. Commonly used needle plates generally use spring pins and needle selection plates to complete the functions of station switching and needle selection. The triangular base plate used in the above manner is not optimized for the realization of multiple functions, and there are certain limitations in needle selection stability and function realization, which limits the diversity of knitting patterns and the improvement of production efficiency.
