Knitting machine with one-pressing-one weaving line structure

The invention discloses a knitting machine with a one-pressing-one knitting line structure, and belongs to the technical field of knitting machines. The knitting machine comprises a disc frame; a fixed frame is arranged at the lower end of the disc frame; an inner spindle is arranged at the end, located on the inner side of the disc frame, of the fixed frame; an outer spindle is arranged at the other end of the disc frame; and inner spindle threads are arranged on thread wheels of the inner spindle. A swing rod structure is changed, a swing rod is driven through force transmitted by a gear and can swing rapidly, the one-pressing-one weaving structure is formed, a mechanism is free of a slip ring and a wavy ring, the remarkable advantages of no oil contamination, no friction and higher swing frequency are brought, and a mechanical structure forming one-pressing-one weaving lines is smaller in size, higher in rotating speed, energy-saving, electricity-saving and low in cost; and a first crank and a second crank
