Both end portions of the first fixed shaft 250 are limited in the first axial hole 231, and both end portions of the second fixed shaft 260 are limited in the second axial hole 232. The position of the locking pin through hole 233 corresponds to the position of the locking groove. A locking pin 234 and a locking spring 235 are provided in the two locking pin through holes 233. The locking pin 234 is placed close to one end of the locking groove, and the locking spring 235 pushes the locking pin 234 into the locking groove. The second fixing ring 240 is sleeved on the outer ring of the first fixing ring 230, and the second fixing ring 240 is used to limit the activity space of the first fixing shaft 250, the second fixing shaft 260 and the locking spring 235, to prevent the first fixing shaft 250 and the second fixing shaft 260 from sliding out along their axial direction, and to provide a support surface for the locking spring 235.

The two sides of the torsion spring 270 are respectively limited in the first heating component 210 and the second heating component 220. The first heating component 210 and the second heating component 220 have a floating function in a close state. When straightening hair, the hair enters between the clamped first heating component 210 and the second heating component 220 from the opening structure 121 of the cold part outer wall 120. Under the action of the hair, the first heating component 210 and the second heating component 220 are slightly stretched and the torsion spring 270 is slightly compressed to produce a certain amount of elastic deformation; after the hair is straightened and removed, the torsion spring 270 is restored to close the first heating component 210 and the second heating component 220 again.

[0033] The automatic styler can switch between the straightening function and the curling function of the automatic styler by pulling out or pressing the first heating component 210 and the second heating component 220 to change the structural positions of the first heating component 210 and the second heating component 220 .

[0034] like Figure 6As shown, the first heating component 210 and the second heating component 220 of the automatic hair styler are pressed downward by an external force, so that the automatic hair styler is in a curling state. In the curling state, the second fixed shaft 260 is at the upper end position of the first deflection folding hole 212 and the second deflection folding hole 222, the first heating component 210 and the second heating component 220 are attached, and a gap of 1mm to 2mm is maintained between the first heating component 210 and the second heating component 220, and the locking pin 234 is in the locking groove at the upper end position. The user puts the hair between the first heating component 210 and the second heating component 220 at the opening structure 121 of the cold portion outer wall 120. The first heating component 210 and the second heating component 220 jointly limit the position of the hair. The two sides of the hair are respectively placed on the first slot 122 and the second slot 123. The first heating component 210 and the second heating component 220 heat the hair. The rotating motor 400 drives the heating component 200 to rotate through the transmission assembly 300. The hair is wound around the outer walls of the first heating component 210 and the second heating component 220 and heated. The formed curled hair is pushed out from the opening structure 121 of the cold portion outer wall 120, and the curling operation is completed.

[0035] When the automatic hair styler needs to be switched from the curling function to the straightening function, the first heating component 210 and the second heating component 220 of the automatic hair styler are pulled upward by an external force, so that the internal structure of the heating component is changed. Figure 6 Convert to Figure 7 Structure. Figure 7 As shown, the automatic styling tool is in a straight hair state, the second fixed shaft 260 is at the lower end position of the first deflection folding hole 212 and the second deflection folding hole 222, the upper ends of the first heating component 210 and the second heating component 220 are slightly opened outward, and the locking pin 234 is in the locking groove at the lower end position. The user puts the hair between the first heating component 210 and the second heating component 220 at the opening structure 121 of the cold part outer wall 120, and the two sides of the hair are placed on the first slot 122 and the second slot 123 respectively. The first heating component 210 and the second heating component 220 heat the hair. The user clamps the hair with the first heating component 210 and the second heating component 220, and pulls the hair out along the first slot 122 or the second slot 123 in a straight line to complete the straight hair operation.
