[0027] In use, first select positioning seat 1 304 and positioning seat 2 305 that correspond to the outer diameter of the enamel tube to be suspended, ensuring that the diameter of the positioning grooves of positioning seat 1 304 and positioning seat 2 305 is consistent with the outer diameter of the enamel tube. Then, connect positioning seat 1 304 to the mounting plate 2 3031 on mounting rod 2 303 using mounting screws. Next, pass the enamel tube through the positioning groove between positioning seat 1 304 and positioning seat 2 305, and place the bottom of the enamel tube over the outside of the limiting seat 401. Positioning pin 404, under the action of positioning spring 406, presses against the inner wall of the enamel tube to center it, ensuring the enamel tube's position does not shift. Then, loosen the screws. Locking nut 3010, under the sliding cooperation of slider 302 and slide groove 103, drives positioning seat one 304 and positioning seat two 305 to move and adjust their positions. Tightening locking nut 3010 limits the position of positioning seat one 304 and positioning seat two 305 and presses positioning seat two 305 inward so that the inner side of positioning seat one 304 and positioning seat two 305 fits tightly against the outer wall of enamel tube. Then tighten positioning nut 308, positioning seat one 304 and positioning seat two 305 limit the position of enamel tube so that the position of enamel tube does not move. Finally, the hanging bracket is hung on the production line for processing by lifting ring 2.
