[0028] The outer ring of the roller bearing is placed on the clamping block 7 through the clamping assembly 6 arranged on the rotating seat 5, and the adjusting knob 91 is turned forward. During the rotation of the adjusting knob 91, the meshing gear is driven to rotate, and the meshing gear and the meshing bevel teeth at the bottom of the meshing gear ring 9 are meshed and transmitted, so that the meshing gear ring 9 rotates, and the transmission thread at the top of the meshing gear ring 9 cooperates with the transmission teeth to transmit, so that the meshing gear plate 8 moves outward as a whole, and then the clamping block 7 moves as a whole, so as to perform auxiliary positioning processing on the outer rings of roller bearings of different sizes, to ensure that the outer ring of the roller bearing can be stably clamped at the corresponding position during the process of hanging hair.
