When the flat knitting machine performs conventional weaving, the movable tooth piece 4 is swung forward by shifting the movable tooth piece 4, and the limit strip 12 is passed through the fixed shaft hole 46 of the movable tooth piece 4 in turn, so that the limit strip 12 is used to fix the movable tooth piece 4, thereby limiting the swinging of the movable tooth piece 4 back and forth, and finally the blocking line is inserted into the plug hole of the movable tooth piece.

[0047] When the flat knitting machine is performing full-form weaving, the limit strip 12 and the stop strip 51 are removed from the needle plate 1 and the movable tooth piece 4 is pushed to swing backward, so that the avoidance groove 43 of the movable tooth piece 4 is moved between the two knitting needles. Finally, the limit strip 12 and the stop strip 51 are further inserted into the needle plate 1, and the limit strip 12 is used to cooperate with the bottom stop of the movable tooth piece 4 to prevent the movable tooth piece 4 from swinging forward under the action of its own weight, thereby ensuring the stability of the movable tooth piece 4 during the full-form weaving process.

[0048] Compared with the first embodiment, the tooth plate and the sinker plate of the present embodiment do not need to be processed to form the first avoidance groove, thereby greatly reducing the processing cost.
