In addition, the first arc-shaped rotating block comprises a first rotating part and a second rotating part, and the first rotating part and the second rotating part are arranged at intervals along the axial direction of the rotating shaft mechanism. The first rotating part comprises a first surface and a second surface which are arranged in a back-to-back mode, the first surface faces the main shaft, the second surface faces the cover plate, and the gap between the first surface and the main shaft is smaller than the gap between the second surface and the cover plate. The second rotating part comprises a third surface and four surfaces which are arranged in a back-to-back mode, the third surface faces the cover plate, the fourth surface faces the main shaft, and the gap between the third surface and the cover plate is smaller than the gap between the fourth surface and the main shaft. When the first swing arm rotates, the first rotating part slides along at least part of the surface of the main shaft, and the second rotating part slides along at least part of the surface of the cover plate.
