When the heating comb is in the folded or unfolded state, the contact point 352 is in the matching hole 252. When the handle 11 rotates relative to the shell 21, the four contact points 352 are respectively moved to the corresponding matching holes.

Since the damping member 35 is sleeved on the washer 34 and fixed on the first connecting member 12, when the first connecting member 12 rotates relative to the second connecting member 23 and the third connecting member 25, the first connecting member 12 drives the damping member 35 to rotate around the main shaft 31. At this time, the washer 34 also provides damping for the rotation of the first connecting member 12 relative to the second connecting member 23 and the third connecting member 25.

[0079] A circular hole 353 is also symmetrically arranged on the damping member 35. The circular hole 353 is located on both sides of the disc through hole.
