A needle tongue knitting needle is horizontally penetrated on the upper part of the movable block. A first limiting hole is provided on the outer wall of the movable block, and a first limiting bolt that contacts and limits the needle tongue knitting needle is screwed into the first limiting hole. Positioning rods are provided on the left side of the movable block and the right side of the fixed block, and also include a spring, and both ends of the spring are respectively sleeved on the two positioning rods. A second limiting hole is provided on the left side of the fixed block, and a second limiting bolt that contacts and limits the connecting rod is screwed into the second limiting hole.

[0005] Furthermore, it also includes a mounting seat and a limiting nut. The other end of the connecting rod has a thread. The top surface of the mounting seat is provided with a positioning hole that is sleeved with the other end of the connecting rod. The limiting nut is threadedly connected to the other end of the connecting rod and clamps and fixes the upper part of the mounting seat. The bottom of the mounting seat is provided with a mounting groove.

[0006] Furthermore, one end of the open-latch knitting needle is bent to form a U-shaped needle head structure.

[0007] Furthermore, the movable block is rotationally connected to the connecting rod.

[0008] Furthermore, a limiting ring for rotationally positioning the movable block is provided on the outer wall of the connecting rod.

[0009] Furthermore, a tool action groove is provided at the end of the connecting rod.

[0010] Furthermore, the tool action groove is one of a straight shape, a cross shape, and a cross shape.

[0011] The beneficial effect of the utility model is as follows: the mounting seat is mounted on the triangular seat of the circular knitting machine, the needle opening latch needle is directly aligned with the lower circle needle of the circular knitting machine, and after being adjusted to contact with the lower circle needle of the circular knitting machine, the first limiting bolt is tightened to fix the needle opening latch needle, and when the machine is running, the needle collides with the needle opening latch needle, so that the needle opening latch needle is knocked open, and the rotation of the movable block and the resetting of the spring are coordinated to achieve the auxiliary opening effect of the needle opening latch needle, so that when the computer jacquard circle transfer machine is running at high speed for a long time, the needle opening latch needle of the circle transfer part can be more flexible and better open to eat the yarn.
