The needle feet of the knitting needle can enter the groove of the cam, move the cam, force the knitting needle to make regular up and down movements in the needle groove of the needle plate, and through the action of the needle hook and the needle tongue, the yarn can be knitted into a knitted fabric. During the rising process of the knitting needle, the coil gradually withdraws from the needle hook, opens the needle tongue, and withdraws the needle tongue to hang on the needle bar; during the descent of the knitting needle, the needle hook hooks the newly placed yarn and pulls it to bend into a coil, while the original coil is out of the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knittings are connected to each other to form a knitted fabric.

The end of the rebound foot 16 is a protrusion 19 with an arc, and the protrusion 19 of the rebound foot 16 is just located on the slide rail of the low-profile insert 4. The pushing part 11 has a limiting slide groove 18, and the limiting slide groove 18 located above the rebound foot 16 is formed by being recessed from bottom to top. The bending position of the limiting slide groove 18 adopts an arc design to ensure that the limiting cylinder 53 of the knitting needle pressure block 5 can slide smoothly along the path.
[0028] The heel 14 of the elastic sinker 1 is pushed forward by the skewer of the mountain board.
