When the first shaft member 11 rotates, the second shaft member 12 is rotated by the connecting rod 21, so that the entire rotation shaft 10 is rotated. During the rotation of the rotating shaft 10, the connecting positions of the connecting rod 21, the first connecting piece 13 and the second connecting piece 14 rotate around the central axis of rotation, so that the connecting rod 21 moves, and then the first magnetic mechanism 30 is driven to move up and down longitudinally. When the second magnetic mechanism 40 pushes the first magnetic mechanism 30, the first magnetic mechanism 30 pushes the rotating shaft 10 to rotate through the connecting rod 21, so that the rotating speed of the rotating shaft 10 is increased.
Further, the projection of the first connecting piece 13 and the second connecting piece 14 at the end of the rotating shaft 10 covers the end of the rotating shaft 10, and the connecting position of the connecting rod 13 and the connecting piece 14 is outside the radial direction of the rotating shaft 10. With such an arrangement, it can be ensured that the movement range of the connecting position of the connecting rod 21 and the first connecting piece 13 and the second connecting piece 14 is larger under the condition that the moving distance of the top end of the connecting rod 21 is not changed, so that the acceleration effect on the rotating shaft 10 can be improved.
