the base is provided with a rotating shaft through-hole and an arc-shaped first slideway, an end of the first slideway communicates with the rotating shaft through-hole, an axis of the first slideway is parallel to an axis of the rotating shaft through-hole, the rotating shaft is provided with an arc-shaped second slideway, an axis of the rotating shaft is parallel to an axis of the second slideway, the second slideway runs through the rotating shaft, and a radius of the second slideway is equal to that of the first slideway;
the rotating shaft is located in the rotating shaft through-hole, and the first slideway and the second slideway can be connected to each other to form a continuous slideway, and the swing arm is located in the continuous slideway and is slidable in the continuous slideway; and
the swing arm is configured to slide in the continuous slideway when the swing arm rotates in a first angle range, and drive the rotating shaft to rotate when the swing arm rotates in a second angle range, wherein a rotation radius of the swing arm in the first angle range is greater than that in the second angle range.

2. The rotating assembly according to claim 1 , wherein the swing arm comprises a body connecting portion, a sliding portion, and a locking portion that are sequentially connected, and the locking portion is located on a side portion of the sliding portion and far away from an end portion of the body connecting portion; and
the sliding portion and the locking portion each have an arc-shaped structure, the sliding portion fits with the continuous slideway, and the locking portion fits with the second slideway.

3. The rotating assembly according to claim 2 , wherein when a rotation angle of the swing arm is a minimum angle of the first angle range, an end portion that is of the locking portion and that is far away from the body connecting portion is in contact with an end portion that is of the first slideway that is far away from the second slideway; or
when the rotation angle of the swing arm is a maximum angle of the first angle range, the locking portion is located in the second slideway, and an end portion that is of the locking portion that is close to the body connecting portion is in contact with an end portion that is of the second slideway that is far away from the first slideway.

4. The rotating assembly according to claim 2 , wherein an arc length of the locking portion is less than that of the second slideway.

5. The rotating assembly according to claim 1 , wherein an inner wall of the rotating shaft through-hole is provided with a first limiting platform, an outer surface of the rotating shaft is provided with a second limiting platform, and the second limiting platform and the first limiting platform are located in a same circumferential direction; and
when the rotation angle of the swing arm is a minimum angle of the second angle range, the first limiting platform is in contact with the second limiting platform, and the first slideway and the second slideway can be connected to each other to form the continuous slideway.

6. The rotating assembly according to claim 1 , wherein an inner wall of the rotating shaft through-hole is provided with a third limiting platform; and
the third limiting platform is configured in such a way that the third limiting platform restrains the swing arm from rotating in an original direction when the rotation angle of the swing arm changes from the minimum angle of the second angle range to a maximum angle of the second angle range.

7. The rotating assembly according to claim 6 , wherein when the rotation angle of the swing arm is the maximum angle of the second angle range, the third limiting platform is in contact with the swing arm.

8. The rotating assembly according to claim 6 , wherein an outer surface of the rotating shaft is provided with a fourth limiting platform, and the fourth limiting platform and the third limiting platform are located in a same circumferential direction;
an arc length distance between the third limiting platform and the fourth limiting platform is greater than or equal to an arc length distance between the third limiting platform and the swing arm; and
when the rotation angle of the swing arm is the maximum angle of the second angle range, the third limiting platform is in contact with the fourth limiting platform.

9. The rotating assembly according to claim 1 , wherein the first slideway is located at a position that is in the rotating shaft through-hole and that is far away from the swing arm.

10. The rotating assembly according to claim 1 , wherein the rotating shaft comprises an assembly column and two support columns;
the assembly column is located between the two support columns, the assembly column and the two support columns are coaxial, and the second slideway runs through the assembly column;
the rotating shaft through-hole comprises a first-section through-hole and two second-section through-holes, wherein the first-section through-hole matches the assembly column, and the second-section through-holes match the support columns; and
the assembly column is located in the first-section through-hole, and the support columns are located in the second-section through-holes.

11. The rotating assembly according to claim 1 , wherein two rotating shaft and two swing arms are provided;
a first side portion and a second side portion of the base are each provided with the rotating shaft through-hole and the first slideway;
the two rotating shafts are located in the rotating shaft through-hole of the first side portion and the rotating shaft through-hole of the second side portion respectively; and
