Walking to complete the tuck; the right tuck preselection triangle (17) preselects the needle for the left needle push triangle (13), and the needle selection foot pushes the push needle into the needle path between the left tuck triangle (8) and the left flat needle triangle (15) under the action of the left needle push triangle (13), and then the push needle pushes the latch needle into the needle path between the left knitting triangle (3) and the needle transfer triangle (1), and the latch needle enters the knitting needle path under the action of the left knitting triangle (3) to knit, and the same knitting tuck is completed at this time; when the head moves from left to right, the right needle connecting triangle (11), the needle transfer triangle (2) and the left knitting triangle (3) are all retracted into the triangle bottom plate (19), and the left needle connecting triangle (9) and the right knitting triangle (4) protrude from the triangle bottom plate (19), and the same knitting tuck needle movement trajectory is symmetrical to the above-mentioned needle movement trajectory when the head moves from right to left; The needle transfer method is as follows: the machine head moves from right to left, the needle transfer cam (2), the left knitting cam (3) and the right knitting cam (4) all protrude from the cam bottom plate (19), the right tuck preselection cam (17) preselects the needle for the left push needle cam (13), the push needle is pushed into the needle path between the left tuck cam (8) and the left flat needle cam (15) by the needle selection foot, the push needle pushes the latch needle into the needle path between the left knitting cam (3) and the needle transfer guard cam (1), and the latch needle is transferred under the action of the left knitting cam (3), the needle transfer cam (2) and the right knitting cam (4); when the machine head moves from left to right, the needle transfer trajectory is symmetrical to the above-mentioned needle path when the machine head moves from right to left; The needle connection method is as follows: the machine head moves from right to left, the needle transfer cam (2), the left knitting cam (3), the right knitting cam (4) and the right needle connection cam (11) all protrude from the cam bottom plate (19), the left needle connection cam (9) retracts into the cam bottom plate (19), the right tuck preselection cam (17) preselects the needle for the left tuck preselection cam (18), the needle selection foot pushes the needle butt of the push needle into the needle connection needle path under the push of the left tuck preselection cam (18), first the needle butt of the push needle moves straight along the left flat needle cam (15) for a distance, and then moves along the tuck transition cam (10) and the right needle connection cam (11) to the right connection needle path. The needle triangle (11) is at the highest point. At this time, the needle butt of the latch needle is pushed by the right knitting triangle (4) and moves along the left wall of the right knitting triangle (4) to complete the needle connection. The needle butt of the push needle moves along the needle path between the right needle connection triangle (11) and the right tuck triangle (12); when the machine head moves from left to right, the needle transfer triangle (2), the left knitting triangle (3), the right knitting triangle (4) and the left needle connection triangle (9) all protrude from the triangle bottom plate (19), and the right needle connection triangle (11) retracts into the triangle bottom plate (19). The needle connection needle movement trajectory is symmetrical with the above-mentioned needle movement trajectory when the machine head moves from right to left; The needle transfer method: the machine head moves from right to left, the needle transfer cam (2), the left knitting cam (3), the right knitting cam (4) and the right needle connection cam (11) all protrude from the cam bottom plate (19), the left needle connection cam (9) retracts into the cam bottom plate (19), the right tuck preselection cam (17) preselects the needle for the left needle push cam (13), the needle selection foot pushes the push needle into the needle path between the left tuck cam (8) and the left flat needle cam (15), the push needle pushes the latch needle into the needle path between the left knitting cam (3) and the needle transfer guard cam (1), the latch needle transfers the needle under the action of the left knitting cam (3), the needle transfer cam (2) and the right knitting cam (4); at the same time, the right tuck preselection cam (17) preselects the needle for the left tuck preselection cam (18), the needle selection foot pushes the push needle under the push of the left tuck preselection cam (18) The needle butt of the push needle enters the needle path of the needle receiving needle. First, the needle butt of the push needle moves straight along the left flat needle triangle (15) for a distance, and then moves along the transition triangle (10) and the right needle receiving triangle (11) to the highest point of the right needle receiving triangle (11). At this time, the needle butt of the latch needle is pushed by the right knitting triangle (4) and moves along the left wall of the right knitting triangle (4) to complete the needle receiving. The needle butt of the push needle moves along the needle path between the right needle receiving triangle (11) and the right tuck triangle (12); when the head moves from left to right, the turning needle triangle (2), the left knitting triangle (3), the right knitting triangle (4) and the left needle receiving triangle (9) all protrude from the triangle bottom plate (19), and the right needle receiving triangle (11) retracts into the triangle bottom plate (19). The needle trajectory of the turning needle is symmetrical with the above-mentioned needle trajectory when the head moves from right to left.
