Say that further said guide piece comprises an elongated needle-like body, said elongated needle-like body has two long sides, and first guide lid and second guide lid are arranged respectively on two long sides; Said first guide lid and second guide lid centre have a yarn guiding trough, an end of yarn guiding trough that one circular-arc yarn guiding port is arranged.
Say that further the said yarn piece that colludes comprises that is colluded a yarn block body, the said yarn block body that colludes comprises a roundlet arc concave surface, and roundlet arc concave surface and first colludes the yarn face and is connected through arc transition, first collude the yarn face the other end connect an orthodrome concave surface through arc transition; The said loose thread that colludes colludes the yarn face with roundlet arc concave surface through second and is connected with an arc surface transition, and said to collude the angle that loose thread and second colludes the yarn face be the obtuse angle; The said yarn groove that colludes is one " U " shape groove, and notch outwardly; Said limit of colluding the yarn groove with collude loose thread and be connected through arc transition.
Say further; The said yarn piece that draws comprises a hook solid body; Said hook solid body comprises that first inclined-plane, first draws the yarn face, second inclined-plane and second draws the yarn face; First inclined-plane and second inclined-plane all are the inclined-planes that tilt, and first inclined-plane, first draws the yarn face, second inclined-plane and second draws the yarn face and is connected through the obtuse angle transition successively; Said hook solid body comprises that also one draws yarn circular arc concave surface, and an end and second that draws yarn circular arc concave surface draws the yarn face and is connected through arc transition, and the other end connects the 3rd through circular arc and draws the yarn face, and the 3rd draws yarn face and the 4th draws the yarn face and be connected through arc transition; The 4th draws the yarn face draws the yarn face through obtuse angle and first and links to each other.
When the present invention worked, the guide piece guided to yarn and colludes the yarn piece and draw in the middle of the yarn piece, draws the yarn face through first inclined-plane and first that draws the yarn piece, made to collude colluding loose thread and successfully yarn being caught on of yarn piece, and yarn is pooled to colluded the yarn groove.
