Improved flat knitting machine knitting needle and use method

The invention belongs to the technical field of textile tools, and particularly relates to an improved flat knitting machine knitting needle and a using method. The knitting needle of the flat knitting machine comprises a needle rod, a needle latch and a needle hook, a diagonal plane of an oval structure is arranged on the outer side curved surface of the needle hook, and the diagonal plane is arranged at the bent position of the upper portion of the needle hook at an angle of 30-40 degrees relative to the bent position of the top of the needle hook and located at an opening where the needle hook and the needle latch extend in a lap joint mode. According to the invention, the problem that the yarn slides over the needle connecting position can be solved, the probability that the yarn ejects the needle latch is greatly improved, the probability that the yarn is aligned with the needle connecting position can be accurately controlled, the problem of missed stitch caused by the fact that the yarn slides over the
