The rotary sealing ring 25 is arranged in the mounting hole 212 and sleeved on the support shaft 23. The rotary sealing ring 25 is used to seal the gap between the hole wall of the mounting hole 212 and the support shaft 23.

[0047] The rotary sealing ring 25 is used to seal the gap between two opposite rotating elements. The rotary sealing ring 25 is arranged on the side of the rotating element 22 away from the drum 12 along the self-axial direction X, that is, in the axial direction X of the rotating element 22, the rotary sealing ring 25 is located between the end of the mounting hole 212 away from the drum 12 and the rotating element 22, and separates the end of the mounting hole 212 away from the drum 12 from the rotating element 22, thereby reducing the influence of the external environment on the rotating element 22. The rotary sealing ring 25 is arranged in the mounting hole 212 and is sleeved on the support shaft 23, that is, the rotary sealing ring 25 is arranged between the hole wall of the mounting hole 212 and the outer surface of the support shaft 23, and the rotary sealing ring 25 is respectively abutted on the hole wall of the mounting hole 212 and the support shaft 23 along the radial direction of the support shaft 23.

[0049] In some embodiments, please refer to Figure 2 and Figure 3 The rotating elements 22 are arranged in plurality along the axial direction X of the support shaft 23, and the connecting mechanism 20 further comprises a plurality of axial positioning members 24, which are respectively arranged on both sides of each rotating element 22 along the axial direction X of the support shaft 23.

[0050] The plurality of rotating elements 22 can support the connecting member 21 at different positions, and the support of the connecting member 21 is more stable.

[0051] The axial positioning member 24 is used to block the movement of the rotating element 22 along the axial direction X, and the plurality of axial positioning members 24 are arranged on both sides of each rotating element 22 along the axial direction X of the support shaft 23, which can block the movement of the rotating element 22 in any direction along the axial direction X of the support shaft 23. Optionally, one axial positioning member 24 can be arranged between two adjacent rotating elements 22, which can reduce the number of axial positioning members 24.
