After the adjusting block 5 is moved to a suitable position, the gripping rod 18 is released, and the clamping block 8 moves upward under the rebound force of the spring 17, so that the clamping tooth 9 is clamped and fixed with the clamping rack 11, and the position of the adjusting block 5 can be fixed. When the installed yarn bobbins are of different lengths, it is necessary to adjust the length of the placing rod 7 according to the specifications of the yarn bobbins so that the bobbins can be adjusted. After the yarn bobbin is completely placed and positioned, it is only necessary to turn the knob 24 to drive the screw rod 23 to rotate, thereby driving the extension rod 20 to telescopically move through the drive block 25, so that the fixed rod 19 and the extension rod 20 are adjusted to a suitable length for placing the yarn bobbin; after the yarn bobbin is sleeved on the surface of the placement rod 7, the fastening nut 15 is loosened outward, so that the rotating shaft 14 can be rotated to adjust the yarn bobbin to a suitable angle to facilitate yarn feeding. After the adjustment is completed, the fastening nut 15 is tightened to make it abut against the connecting block 13 to achieve the fixation of the support seat 6.
