In other embodiments, the first transition angular position is not necessarily located at the middle between the first initial angular position and the first end angular position, the second transition angular position is not necessarily located at the middle between the second initial angular position and the second end angular position, and the angular difference between the first initial angular position and the first end angular position and the angular difference between the second initial angular position and the second end angular position may be other than 180 degrees, which is not limited to the present embodiment. In addition, the operation modes of the two bodies are only examples, that is, the two bodies are not necessarily switched between two folding states, and the present embodiment should not be limited thereto.

Further, the inner wall surface of the fourth deep groove 331b of the fourth groove 331 of the second shaft 3 is stopped by the second slider 42 in the second rotation direction R2, so that the second shaft 3 is prevented from rotating in the second rotation direction R2. Further, since the first gear portion 241 faces away from the first idler gear portion 51 and the second gear portion 341 faces away from the second idler gear portion 61, the first gear portion 241 and the second gear portion 341 do not interlock with the second idler gear portion 61 through the first idler gear portion 51, and in this state, the first protrusion 242 is positioned in the first recess 52 to restrict rotation of the first idler gear 5, the second protrusion 342 is positioned in the second recess 62 to restrict rotation of the second idler gear 6, the first start gear portion 243 is not engaged with the first start idler gear portion 53, and the second start gear portion 343 is not engaged with the second start idler gear portion 63.

Further, the first gear portion 241 is engaged with the first idle gear portion 51, but the second gear portion 341 faces away from the second idle gear portion 61, so that the first gear portion 241 and the second gear portion 341 are not interlocked with the second idle gear portion 61 by the first idle gear portion 51.
Referring to fig. 22 to 26, when the first shaft 2 is at the first transition angle position and the second shaft 3 is at the second transition angle position, the first groove 221 faces the first slider 41 and the third deep groove 321a of the third groove 321 faces the first slider 41, so that the first slider 41 is slidably and partially accommodated in the first groove 221 or/and the third deep groove 321a of the third groove 321, in this embodiment, the first slider 41 is still accommodated in the first groove 221, but it is required to be stated that, when the first shaft 2 rotates in the first rotation direction R1, the first shaft 2 forces the first slider 41 to slide towards the third deep groove 321a of the third groove 321, and the second groove 231 faces the second slider 42 and the fourth shallow groove 331a of the fourth groove 331 faces the second slider 42, so that the second slider 42 is partially accommodated in the fourth groove 331a and cannot be slid in the fourth groove 331a. Further, the inner wall surface of the second groove 231 of the first shaft 2 is stopped by the second slider 42 in the second rotation direction R2 to prevent the first shaft 2 from rotating in the second rotation direction R2. Further, since the first gear portion 241 is engaged with the first idler gear portion 51 and the second gear portion 341 is engaged with the second idler gear portion 61, the first gear portion 241 and the second gear portion 341 are interlocked with each other by the first idler gear portion 51 and the second idler gear portion 61, and in this state, the first protrusion 242 is about to be disengaged from the first recess 52 to allow the first idler gear 5 to rotate, the second protrusion 342 is about to be disengaged from the second recess 62 to allow the second idler gear 6 to rotate, and the first start gear portion 243 is engaged with the first start idler gear portion 53 and the second start gear portion 343 is engaged with the second start idler gear portion 63.

Further, since the first gear portion 241 is engaged with the first idler gear portion 51 and the second gear portion 341 is engaged with the second idler gear portion 61, the first gear portion 241 and the second gear portion 341 are interlocked with each other by the first idler gear portion 51 and the second idler gear portion 61.
Referring to fig. 30 to 34, when the first shaft 2 is at the first end angular position and the second shaft 3 is at the second end angular position, the first groove 221 faces away from the first slider 41 and the third deep groove 321a of the third groove 321 faces the first slider 41, so that the first slider 41 cannot be slidably and partially accommodated in the third deep groove 321a of the third groove 321, and the second groove 231 faces the second slider 42 and the fourth shallow groove 331a of the fourth groove 331 faces the second slider 42, so that the second slider 42 cannot be slidably and partially accommodated in the second groove 231 and the fourth shallow groove 331a of the fourth groove 331. Further, the first gear portion 241 is engaged with the first idle gear portion 51, the second gear portion 341 is engaged with the second idle gear portion 61, and therefore, the first gear portion 241 and the second gear portion 341 are interlocked with each other by the first idle gear portion 51 and the second idle gear portion 61, and in this state, the first protrusion 242 is out of the first concave portion 52, and therefore, the first idle gear 5 is rotatable, the second protrusion 342 is out of the second concave portion 62, and therefore, the second idle gear 6 is rotatable, and the first start gear portion 243 and the first start idle gear portion 53 are not engaged with each other, and the second start gear portion 343 and the second start idle gear portion 63 are not engaged with each other.
In this case, in the present embodiment, the inner wall surface of the second groove 231 of the first shaft 2 is stopped by the second slider 42 in the first rotation direction R1, thereby preventing the first shaft 2 from rotating in the first rotation direction R1, and the inner wall surface of the third deep groove 321a of the third groove 321 of the second shaft 3 is stopped by the first slider 41 in the second rotation direction R2, thereby preventing the second shaft 3 from rotating in the second rotation direction R2. However, in other embodiments, other stoppers may be provided to prevent the first shaft 2 from rotating in the first rotation direction R1 and to prevent the second shaft 3 from rotating in the second rotation direction R2, which is not limited to the present embodiment.
In addition, for the summary of the actions between the structures on the first gear member 24, the second gear member 34, the first idler gear 5 and the second idler gear 6, the first idler gear portion 51 and the second idler gear portion 61 are engaged between the first gear portion 241 of the first gear member 24 and the second gear portion 341 of the second gear member 34 when the first shaft 2 is between the first transition angular position and the first end angular position, and the second shaft 3 is between the second transition angular position and the second end angular position, thereby moving the first shaft 2 and the second shaft 3 in synchronization. When the first shaft 2 is between the first initial angular position and the first transition angular position and has not reached the first transition angular position, the first protrusion 242 is located in the first recess 52 to restrict the rotation of the first idler tooth 5, when the first shaft 2 is rotated to the first transition angular position, the first protrusion 242 is gradually removed from the first recess 52 to allow the rotation of the first idler tooth 5, and when the second shaft 3 is between the second initial angular position and the second transition angular position and has not reached the second transition angular position, the second protrusion 342 is located in the second recess 62 to restrict the rotation of the second idler tooth 6, and when the second shaft 3 is rotated to the second transition angular position, the second protrusion 342 is gradually removed from the second recess 62 to allow the rotation of the second idler tooth 6. Thereby, the first idler gear 5 and the second idler gear 6 can be prevented from idling when the first gear portion 241 of the first rotating shaft 2 and the second gear portion 341 of the second rotating shaft 3 are not interlocked. In addition, when the first shaft 2 is at the first transition angle position, the first start gear portion 243 and the first start idler gear portion 53 are engaged with each other, and when the second shaft 3 is at the second transition angle position, the second start gear portion 343 and the second start idler gear portion 63 are engaged with each other, whereby the interlocking performance and the engagement strength between the first shaft 2 and the first idler gear 5 and between the second shaft 3 and the second idler gear 6 can be ensured at the moment when the first shaft 2 and the second shaft 3 start to interlock with each other through the first idler gear 5 and the second idler gear 6.
However, in a variant embodiment, the first idler gear 5 and the second idler gear 6 may be omitted, and the first protrusion 242 of the first gear member 24 and the second protrusion 342 of the second gear member 34 may be omitted, and in this case, the first gear portion 241 of the first gear member 24 and the second gear portion 341 of the second gear member 34 may be directly meshed with each other to be interlocked, and the first start gear portion 243 of the first gear member 24 and the second start gear portion 343 of the second gear member 34 may also be directly meshed with each other to be interlocked.
In summary, according to the present invention, by the cooperation between the first rotating shaft 2, the second rotating shaft 3, and the first slider 41 and the second slider 42 of the slider set 4, and the cooperation between the first gear portion 241 of the first rotating shaft 2 and the second gear portion 341 of the second rotating shaft 3, the first rotating shaft 2 and the second rotating shaft 3 can rotate in turn and then synchronously rotate during the pivoting process, so as to achieve multi-stage switching with three or more stages.
