Flat knitting machine structure with adjustable gap between two knock-over bits

A flat knitting machine structure with an adjustable gap between two knock-over bits, comprising:

• two needle beds, respectively comprise a plurality of needles and a plurality of knock-over bits disposed to correspond to each of the plurality of needles, wherein each of the plurality of needles comprises a butt;
• each of the plurality of knock-over bits comprises a control butt disposed at a same side as each of the butts;
• the two needle beds are disposed at interval so that the plurality of knock-over bits face each other to define a gap;
• a distance of the gap is equal to a space between two knock-over bits facing each other;
• each of the plurality of needles defines a needle extending line;
• each of the butts is respectively positioned on one of the needle extending lines;
• each of the control butts is respectively positioned on one of the needle extending lines of which one of the plurality of needles is correspondingly disposed;
• each of the plurality of knock-over bits comprises an extending section provided with the control butt, a bending section connected with the extending section and a loop hanging section connected with the bending section as well as paralleled to a front edge of one of the needles, wherein each of the plurality of knock-over bits further comprises a wire mounting hole for loosening loop located on the loop hanging section, wherein the at least one wire mounting hole for limiting position is an oblong hole;
• and at least one wire mounting hole for limiting position located on the extending section;
• and
• two cam systems, respectively disposed to face one of the needle beds, wherein each of the cam systems comprises a needle cam to provide the butts being placed and guide each of the plurality of needles to make a knitting stroke towards the gap, and a knock-over bit cam provides the control butts being placed;
• and the knock-over bit cam is controlled to define a displacement stroke for driving the plurality of knock-over bits to change a size of the gap, wherein the plurality of knock-over bits are driven to perform a linear stroke which is parallel to the needle extending line.
