[0037] See also Figure 2 and Figure 6 Specifically, during the adjustment process, the bearing assembly 2 passes through the support shaft 1d of the spinning machine so that the bearing assembly 2 can rotate on the support shaft 1d, wherein the bearing assembly 2 includes a bearing member 21 and a bearing seat 22, the bearing seat 22 is fixedly installed at the first installation position 111, and a bearing installation position 221 is opened in the middle of the bearing seat 22, the bearing member 21 is arranged in the bearing installation position 221, and the edge of the bearing installation position 221 extends a limit block 2211 along its axial direction, and a limit member 211 is provided on the bearing member 21. When the bearing member 21 rotates, the limit member 211 rotates with the bearing member 21 until the limit member 211 abuts against the limit block 2211. At this time, the bearing member 21 is limited by the limit block 2211 and no longer rotates, thereby limiting the rotation stroke of the bearing member 21.
