The vertical guide groove 2041 in the vertical guide rail 204 comprises a first guide groove 2043 and a second guide groove 2044 which are not communicated, and the first guide groove and the second guide groove in the vertical guide groove in the prior art are communicated into a whole, but the vertical guide groove is easy to break, and the first guide groove 2043 and the second guide groove 2044 are not communicated, so that the physical characteristics of the component structure of the vertical guide groove 2041 are improved, and the breakage resistance is high; one end of the second guide groove 2044 is communicated with the inclined guide groove 2042, and the other end of the second guide groove 2044 is also provided with a mounting groove 2045; the first guide post 2033 of the main body portion 2031 is provided in the first guide groove 2043 of the vertical guide groove 2041, and the second guide post 2034 is provided in the second guide groove 2044 through the mounting groove 2045, so that the main body portion 2031 of the yarn nozzle slide bar 203 can slide into the inclined guide groove 2042 through the second guide groove 2044 of the vertical guide groove 2041.
The bending angle of the bending portion 2032 of the yarn nozzle slide rod 203 relative to the main body portion 2031 is positively correlated with the inclination angle of the inclined guide groove 2042 relative to the vertical guide groove 2041, i.e., the yarn nozzle slide rod 203 with the appropriate bending angle and the uberculous seat 201 with the appropriate inclination angle can be selected according to the position of the yarn nozzle assembly 104 provided in the flat knitting machine 100. The yarn nozzle assembly 104 is arranged near the center of the flat knitting machine 100, the bending angle is smaller, and the inclination angle of the inclined guide groove 2042 relative to the vertical guide groove 2041 is correspondingly smaller, so that the swinging angle of the yarn nozzle assembly 104 is smaller during working; the yarn nozzle assembly 104 is arranged at a position far away from the center of the flat knitting machine 100, and as the yarn nozzle assembly 104 is further away from the center of the flat knitting machine 100, the bending angle is larger, the inclination angle is correspondingly larger, and the swinging angle of the yarn nozzle assembly 104 is larger during working.
