The invention relates to the field of Intasia horizontal knitters, in particular to a yarn nozzle carrying device on an Intasia horizontal knitter. The yarn nozzle carrying device is arranged at one side of a yarn nozzle storage rack and comprises a carrying mechanism, a rack and a machine head, the machine head is arranged on the rack in a transverse sliding mode, and the carrying mechanism can be arranged on the machine head or the rack in a transverse moving mode; therefore, the carrying mechanism can transversely move relative to the machine head and the yarn nozzle storage rack. By means of the yarn nozzle carrying device, the Intasia horizontal knitter can carry out Intarsia knitting and laying-in knitting. Meanwhile, the edge breaking phenomenon can be avoided without stopping the machine head to push a yarn nozzle to the yarn nozzle storage rack on the boundary of a knitting area, the machine head does not need to be stopped to convey the yarn nozzle to the carrying mechanism at the returning knitting initial stage of the machine head, and therefore knitting efficiency is greatly improved.
