The curling rod 1 also includes a first-pole fixed curved surface ring contact piece 60, a second-pole fixed curved surface ring contact piece 80, a first-pole rotating circular ring contact piece 50 and a second-pole fixed curved surface ring contact piece 80. The first-pole fixed curved surface ring contact piece 60 and the second-pole fixed curved surface ring contact piece 80 are both fixedly mounted on the handle shell 10. The second-pole fixed curved surface ring contact piece 80 is coaxially spaced with the first fixed ring contact piece. The first-stage rotating circular ring contact piece and the second-stage rotating circular ring contact piece 70 are both fixedly mounted on the curling roller 20. The first pole rotating annular contact piece 50 is vertically arranged opposite to the first pole fixed curved surface ring contact piece 60, and the second pole rotating annular contact piece 70 is vertically arranged opposite to the second pole fixed curved surface ring contact piece 80. The first pole fixed curved surface ring contact piece 60 tilts toward the first pole rotating annular contact piece 50 to form at least one first pole elastic tilting portion abutting against the first pole rotating annular contact piece 50. The second pole fixed curved surface ring contact piece 80 tilts toward the second pole rotating annular contact piece 70 to form at least one second pole elastic tilting portion 81 abutting against the second pole rotating annular contact piece 70. Both the first elastic tilting portion and the second elastic tilting portion are in a state of elastic compression deformation.

[0039] Specifically, the curling rod 1 includes a handle shell 10, a curling drum 20, a motor 30 and a control panel 40. The curling drum 20 is connected to the motor 30 in a transmission manner. The motor 30 rotates to drive the curling drum 20 to rotate relative to the handle shell 10. The control panel 40 is electrically connected to the motor 30, and the start and stop of the motor 30 are controlled by the control panel 40. The motor 30 and the control panel 40 are both installed inside the handle shell 10. The curling rod 1 also includes a first-pole rotating annular contact piece 50, a first-pole fixed curved surface ring contact piece 60, and a second-pole rotating annular contact piece 70 and a second-pole fixed curved surface ring contact piece 80, which are arranged opposite to each other up and down. The first-pole rotating annular contact piece 50 and the second-pole rotating annular contact piece 70 are arranged coaxially and spaced apart, and both are installed on the curling drum 20.

In this embodiment, when the first elastic tilting portion abuts against the first pole rotating circular ring contact piece 50, it is in an elastically compressed state, so the first elastic tilting portion has an elastic force, which can make the first elastic tilting portion always close to the first pole rotating circular ring contact piece 50 to ensure that the electrical contact is more stable. Similarly, when the second elastic tilting portion abuts against the second pole rotating circular ring contact piece 70, the second elastic tilting portion is also in an elastically compressed state.

[0040] It should be noted that the first electrode and the second electrode in the present application are the positive electrode and the negative electrode, and the specific polarity can be set arbitrarily and is not limited here.

The second convex wall ring 2234 can separate the second pole rotating ring contact 70 and the second pole fixed curved ring contact 80, and separate the first pole rotating ring contact 50 and the first pole fixed curved ring contact 60 from the outside, thereby reducing the contact of external parts and foreign objects with the second pole rotating ring contact 70, the second pole fixed curved ring contact 80, the first pole rotating ring contact 50, and the first pole fixed curved ring contact 60, thereby increasing the safety performance of the device.

[0057] In this embodiment, the first pole rotating annular contact piece 50 has a plurality of first connecting legs 51, the second pole rotating annular contact piece 70 has a plurality of second connecting legs 71, and the first end cover 223 has a first positioning groove for the first connecting legs 51 and the second connecting legs 71 to pass through. The first pole fixed curved surface ring contact piece 60 has a plurality of third connecting legs 62, the second pole fixed curved surface ring contact piece 80 has a plurality of fourth connecting legs 82, and the second end cover 100 has a second positioning groove for the third connecting legs 62 and the fourth connecting legs 82 to pass through. The first connecting leg 51 and the second connecting leg 71 pass through the first positioning groove and are clamped in the first positioning groove, and the third connecting leg 62 and the fourth connecting leg 82 pass through the second positioning groove and are clamped in the second positioning groove. The number of the first connecting leg 51, the second connecting leg 71, the third connecting leg 62, and the fourth connecting leg 82 can all be set to two. Of course, more numbers can also be set, and the specific number is not limited here.

[0058] The third connection leg 62 is located at a position other than the first pole elastic tilting portion of the first pole fixed curved surface ring contact piece 60; the fourth connection leg 82 is located at a position other than the second pole elastic tilting portion 81 of the second pole fixed curved surface ring contact piece 80. Specifically, the first elastic tilting portion tilts toward the first pole rotating circular ring contact piece 50, so the first pole fixed curved surface ring contact piece 60 has two tilting and valleys, and the third connection leg 62 is located at the valley position of the first pole fixed curved surface ring contact piece 60. Similarly, the fourth connection leg 82 is located at the valley position of the second pole fixed curved surface ring contact piece 80.
