the first shifting piece and the second shifting piece are the same in number and are same in arrangement number;

the machine needle comprises a stitch, a needle rod, a needle hook, a needle latch, a needle tooth and a lower stitch;

the needles are sequentially arranged in the needle grooves in groups, and the axial positions of the needle teeth of the needles in the same group are different;

the needle can vertically move in the needle groove;

the machine needle is fixed relative to the circumferential direction of the needle cylinder;

the first shifting piece is provided with a first surface, and the first surface and the machine needle can be contacted under the driving of the first shifting piece; so that the needle, which is in contact with it during operation, undergoes a change in vertical position during the axial rotation around the needle cylinder;

the second poking piece is provided with a second surface, and the second surface and the machine needle can be in contact under the driving of the second poking piece; so that the needle, which is in contact with it during operation, undergoes a change in vertical position during the axial rotation around the needle cylinder;

the first contact end of the first surface and the needle is an input end, and the second contact end of the first surface and the needle is an output end;

the end of the second surface, which is firstly contacted with the needle, is an input end, and the end, which is finally contacted with the needle, is an output end; the output ends of the first shifting piece and the second shifting piece with the same number are different in height;

when the needle cylinder rotates, the needle teeth can be in contact with or not in contact with the first shifting piece and the second shifting piece with the same serial number in sequence to perform corresponding needle selection or non-needle selection actions, so that the machine needle can be positioned after passing through the needle selection component: any working position of the loop withdrawing working position, the yarn laying working position and the loop forming working position;

after the needle teeth pass through the needle selection component, the stitch contacts with a reset component.

In the technical scheme, the knitting machine provided by the invention is improved from the conventional knitting machine which only has a needle selector with a single function and is provided with various parts specially used for realizing different knitting needle actions, and the knitting needle action is completed by mainly utilizing the needle selector with two functions and the knitting unit of the corresponding reset part, so that the knitting machine has the advantage of simple structure.

The invention only needs to use two rows of needle selector plectrums to select needles, and can realize that any needle is in any one of three different working positions, namely a looping working position, a loop withdrawing working position and a yarn laying working position, and the needle can be randomly changed among the three working positions;
