The invention discloses an adjustable yarn frame. A track is arranged on the ground. Movable bases are arranged on the left side and the right side of the track correspondingly, and supporting rods are arranged on the moving bases. Clamps used for installing yarn coils are arranged at the upper ends of the supporting rods. Through grooves are formed in the middle portions of the supporting rods. Telescopic supporting arms are arranged in the through grooves, and positioning rings are arranged at the ends of the supporting arms. The rack is arranged, and the movable bases are arranged on the track for clamping the yarn coils for paying off yarns, so that the adjustable yarn frame is simple in structure and convenient to operate, and the yarn paying-off efficiency of the yarn coils is greatly improved.
