In order to solve the technical problems, the invention adopts the following technical scheme: a trocar weaving station walking method mainly comprises the following steps: the knitting machine comprises a first knitting needle and a second knitting needle, wherein the first knitting needle is provided with a first latch, a first hook and a first widening stitch piece, and the second knitting needle is provided with a second latch, a second hook and a second widening stitch piece.

The method comprises the following steps: the first knitting needle is obliquely and upwards displaced to the needle turning position of the highest position, the loop slides to the position of a first widening sheet from the front end of the first knitting needle, a first latch is brushed to open a first needle hook, and a second widening sheet of the second knitting needle catches the previous old loop;

step two: the second knitting needle moves obliquely upwards and penetrates through the inner side of a first ring expanding sheet of the first knitting needle, the first ring expanding sheet brushes a second latch of the second knitting needle, a second hook is used for hooking the coil, and the yarn is fed to the first hook at the top end of the first knitting needle by the sand nozzle;

step three: the second knitting needle moves downwards in a slant resetting way, the second hook hooks the coil to slide downwards, the old coil hooked on the second loop expanding sheet slides upwards and closes the second latch, so that the coil passes through the old coil to finish the looping action.

Specifically, the outer sides of the first ring expanding sheet and the second ring expanding sheet are both provided with ring expanding sheet grooves, and the ring expanding sheet grooves are sunken towards the inner side.

Specifically, the coil in the first step is drawn by the groove of the ring expanding sheet outside the first ring expanding sheet to move obliquely upwards, and the old coil is drawn by the groove of the ring expanding sheet outside the second ring expanding sheet to move obliquely upwards.

Specifically, when the second knitting needle in the second step passes through the first knitting needle, the expanded loop piece groove on the first expanded loop piece brushes a second latch on the second knitting needle, the second latch is turned backwards, and the second hook is opened.

Specifically, when the second knitting needle in the third step is reset obliquely downwards, the ring expanding piece groove on the first ring expanding piece drives the second latch to turn forwards, and the second latch and the second hook are closed.

Compared with the prior art, the beneficial effects are: on the basis of a motor type double-layer stitch cam, the combined station action is optimized again, and the function of a trocar can be realized by moving a special needle from left to right; the trocar can be shown in a forward turning and backward turning manner or forward turning and backward turning manner, and 8 actions of weaving, mesh hanging, tight weaving, two-layer hanging, two-layer weaving, weaving and hanging, trocar and non-weaving can be realized. In structural design, the needle widening ring piece is different from the prior one, and a groove is added; redesigning the knitting and needle-turning triangular needle-moving surface; the trocar function is newly added, and the original functions only comprise three common functions of knitting, needle turning and eye hanging and combination; every time a function is added and recombined and optimized, the pattern organization structure can be greatly enriched.
