In addition, the rotational connection is largely divided into a rolling connection and a sliding connection, so that the rotational assembly 50 may also be provided as a rolling assembly or a sliding assembly, respectively.

As shown in fig. 3, the rotating assembly 50 is provided with a rolling bearing 51, an inner ring of the rolling bearing 51 is fixedly connected with the support shaft 13, an outer ring of the rolling bearing 51 is fixedly connected with the housing 20, and the housing 20 rotates on the support shaft 13 through the rolling bearing 51. In particular, for a rotational connection, a rolling connection is the best way, for example by means of rolling bearings 51, to achieve a smooth rotation of the housing 20 along the support shaft 13. In addition, the rolling bearing 51 has a stopper function in the axial direction thereof, and therefore it is possible to restrict the displacement of the housing 20 in the axial direction of the support shaft 13, thereby reducing the shake of the housing 20 in the axial direction of the support shaft 13.

As shown in fig. 4, the rotating assembly 50 is provided with a sliding sleeve 52, the inner side of the sliding sleeve 52 is fixedly connected with the support shaft 13, the outer side of the sliding sleeve 52 is slidably connected with the housing 20, and the housing 20 rotates on the support shaft 13 through the sliding sleeve 52. In particular, the sliding sleeve 52 is lighter in weight relative to the rolling bearing 51 and can also be used at the articulation between the housing 20 and the support shaft 13. The sliding bush 52 is preferably made of a steel material or a ceramic material having a low coefficient of dynamic friction.

As shown in fig. 4, the sliding shaft sleeve 52 is provided with a limiting projection 53, the housing 20 is provided with a corresponding limiting notch 22, and the limiting projection 53 and the limiting notch 22 abut against each other to limit the housing 20 together so as not to displace in the axial direction of the supporting shaft 13. The sliding shaft sleeve 52 is provided with a first shaft sleeve 54 and a second shaft sleeve 55, the first shaft sleeve 54 is provided with a first lug 56, and the first lug 56 is positioned at one end of the first shaft sleeve 54 facing the free end 12; the second sleeve 55 is provided with a second projection 57, the second projection 57 being located at an end of the second sleeve 55 facing the abutment end 11. The limiting notch 22 is provided with a first notch 23 and a second notch 24, and the first notch 23 is positioned at a position on the shell 20, which is abutted against the first bump 56, and is abutted against the first bump 56; the second notch 24 is located at a portion of the housing 20 that abuts against the second bump 57 and abuts against the second bump 57.

Specifically, since the sliding shaft sleeve 52 has no limiting function of the rolling bearing 51 in the axial direction, the sliding shaft sleeve 52 is provided with the limiting projection 53, the housing 20 is provided with the limiting notch 22, and the limiting projection 53 and the limiting notch 22 cooperate to form a limiting function, so that the housing 20 is limited in the axial direction of the supporting shaft 13 without displacement, and shake of the housing 20 in the axial direction of the supporting shaft 13 is reduced. It will be appreciated that to better limit the jitter of the housing 20, the first tab 56 and the first notch 23 are positioned facing the free end 12, thereby limiting the displacement of the housing 20 toward the free end 12; the second projection 57 and the second notch 24 are disposed facing the mating end 11 so as to limit displacement of the housing 20 toward the mating end 11. It will be appreciated that the above arrangement may be reversed, i.e. the first projection 56 and the first notch 23 are arranged facing the abutment end 11, and the second projection 57 and the second notch 24 are arranged facing the free end 12, as long as it is achieved that the displacement of the housing 20 in the axial direction of the support shaft 13 is limited.

As shown in fig. 3 and 4, the inside of the support shaft 13 is hollow so as to pass through the cable of the power assembly 30. The driving power of the driving motor 31 is transmitted through a cable, one end of the cable is connected to the electrical connector of the driving motor 31, and the other end of the cable passes through the hollow region inside the supporting shaft 13 to be connected to the electrical connector (not shown) of the docking end 11, and when the docking end 11 is docked with the external hair styling apparatus, the electrical connector of the docking end 11 is electrically contacted with the corresponding electrical connector of the external hair styling apparatus to thereby introduce the power to the driving motor 31 for operation. It will be appreciated that the external hair styling apparatus may also be provided with switching means for driving the motor 31 and speed and direction regulating means.

When in use, the butt joint end 11 of the hairdressing device is connected to the corresponding butt joint position of the external hairdressing device, so that the hairdressing device is firmly fixed on the external hairdressing device, and the electric connector of the butt joint end 11 and the electric connector of the external hairdressing device form electric connection, thereby supplying power to the driving motor 31. The hairline is clamped or wound on the hair styling apparatus, and the power of the blower of the external hair styling apparatus is turned on, so that the external hair styling apparatus can blow hot air, and the hot air enters the interior of the hair styling apparatus through the passage of the butt-joint end 11, and is then discharged from the air outlet of the hair styling apparatus housing 20, thereby drying or styling the hairline.

Then, the power switch of the driving motor 31 on the external hairdressing apparatus is turned on, so that the driving motor 31 starts to operate to drive the casing 20 to rotate, thereby driving the hairline on the casing 20 to rotate, forming the hair curling effect, and shaping by continuous blowing of hot air. When the hairline on one side is wound after the hairline on the other side is shaped, the direction-adjusting switch on the external hairdressing equipment can be pressed to adjust the rotation direction of the shell 20, and the hairline is wound from the other direction, so that a better hair curling and shaping effect is achieved.

When the driving motor 31 is operated, the rotation power is transmitted to the transmission end cover 41 through the output shaft 33, and the transmission end cover 41 transmits the rotation power to the driven groove 21 on the housing 20 through the transmission lug 43, so that the housing is driven to rotate. The housing 20 is rotated about the support shaft 13 by the rotating assembly 50 so that the hair strands also rotate with the housing to create a curling effect.

Therefore, the utility model can realize the simple, convenient and low-cost connection of the driving motor 31 and the shell 20, and the shell 20 and the rotating shaft can also rotate smoothly, thereby reducing the production cost and improving the use feeling of users.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
