The flat spiral spring 42 applies upward rotation torsion to the driver body 20 to make the side surface of the roller 30 closely contact with the arc surface of the lower part of the rocking chair, and because the force generated by the flat spiral spring 42 is elastic torsion, when the height of the arc surface of the lower part of the rocking chair is changed, the height of the roller 30 can be changed under the action of the elastic torsion, so that the roller 30 is kept in contact with the lower part of the rocking chair.
The screw pair adopts a ball screw pair, and comprises a screw 44, a moving piece 45 sleeved on the screw 44 and a guide rail arranged in parallel with the screw 44, wherein the axis of the screw 44 is perpendicular to the different plane of the axis of the first rotating shaft 41. The moving member 45 is a nut member, the moving member 45 moves along the guide rail, in this embodiment, a bayonet structure matched with the guide rail is formed on the moving member 45, and the screw rod 44 can prevent the moving member 45 from rotating along with the screw rod 44 through a fastening structure in the process of rotationally driving the moving member 45.

When the swing driving device is driving the swing, the third rotating shaft 53 on the self-locking lever 33 is located in the free slide 55 and moves up and down in the free slide 55, and does not enter the limit area 56. Thereafter, if the rocking chair driving device is to be retracted, i.e. the driving end is pressed down once, the third rotating shaft 53 enters the first sliding way 51 from the free sliding way 55, when a user perceives that the third rotating shaft 53 is propped against the top of the first sliding way 51, i.e. the third rotating shaft 53 moves to the outlet of the first sliding way 51, the user can loose his hands, under the torsion action of the flat spiral spring 42, the driving end has a tendency to spring up, then the third rotating shaft 53 enters the limit area 56 and moves to the second corner along the first guiding surface 581, the side surface of the third rotating shaft 53 has a downward acting force on the limit structure 570, i.e. a downward acting force on the driving end, and the upward spring tendency generated by the torsion force of the flat spiral spring 42 on the driving end can be balanced, so that self-locking is realized. If the rocking chair driving device is to be used again, i.e. the driving end is pressed down once again, the third rotating shaft 53 is separated from the limit area 56 along the second guide surface 582 and moves to the entrance of the second slideway 52, when the user perceives that the third rotating shaft 53 props against the top of the second slideway 52, the user can loose his hands, under the torsion action of the flat spiral spring 42, the driving end is sprung up, and the third rotating shaft 53 moves along the second slideway 52 and enters the free slideway 55, so as to realize unlocking.
In this embodiment, the vertex of the first angle is close to the outlet of the first slide 51, and the vertex of the second angle is close to the inlet of the second slide 52, so that the third rotating shaft 53 does not return to the first slide 51 along the first guiding surface 581 but only enters the second slide 52 along the second guiding surface 582 when the driving end is pressed for the second time.
In this embodiment, the limiting structure 570 has a third guiding surface 573 as a sidewall at the entrance of the first slide way 51, the third guiding surface 573 is an inclined surface, and the third guiding surface 573 faces the upper port of the free slide way 55 and is located above the upper port of the free slide way 55, so that the third rotating shaft 53 can only enter the first slide way 51 at the exit of the free slide way 55 under the guidance of the third guiding surface 573.
In this embodiment, the handle is disposed on the driver body 20 to facilitate the lifting of the swing drive.
Embodiment two:
the difference between this embodiment and the first embodiment is that the torsion adjusting mechanism includes only the flat spiral spring 42 and the adjusting ring 43, and the adjusting ring 43 is fixed to the inner wall of the driver body 20, that is, in this embodiment, the torsion of the flat spiral spring 42 cannot be manually adjusted.
