[0027] Specifically, the positioning assembly 5 is symmetrically sleeved on the outside of the winding rod 4. The positioning assembly 5 is used to limit the position of the spring wire after rotation. The positioning assembly 5 includes a positioning box 501 sleeved on the outside of the winding rod 4. The inner wall of the positioning box 501 is symmetrically hinged with a pressure plate 502 for frictionally fixing the winding rod 4. A limit line block 5011 is provided on the side of the positioning box 501. The side of the positioning box 501 is threadedly connected with an extrusion bolt 505 for extruding the pressure plate 502.

[0028] It should be noted that the positioning box 501 and the line limiting block 5011 are fixed with glue.
