According to some embodiments of the present utility model, the folder 110 is provided with a limiting groove 260, and the first end 270 of the second control member 130 is positioned in the limiting groove 260. Referring to fig. 2 and 3, since the first end 270 is in the limiting groove 260, the rotational range of the folder 110 in the rotatable state is limited by the limiting groove 260, and the first end 270 can be separated from the limiting groove 260 upward by pressing the second control member 130 from the bottom up, the rotational range of the folder 110 in the rotatable state is increased, and folding and storage are facilitated.

It will be appreciated that when the folder 110 is applied to the infant rocking chair, the rotation of the folder 110 within the range limited by the limiting groove 260 can adjust the angle of the infant rocking chair, thereby improving the comfort of the user.

It should be noted that, the number of the first ends 270 of the second control member 130 may be adjusted according to the requirement, referring to fig. 3, two first ends 270 are respectively located in two limiting slots 260, and if one limiting slot 260 of one folding member 110 has no corresponding first end 270, it is not limited by the first ends 270, and it is understood that a plurality of folding members 110 may be selected according to the requirement and limited by the first ends 270.

According to some embodiments of the present utility model, fig. 4 is an exploded view of a folding device, in which there are three folding members 110, three first control members 120 and their corresponding first springs 240, and three first internal gears 210, second internal gears 220 and third external gears 230, and second control members 130 and their corresponding second springs 250 are provided. It will be appreciated that the folding device is simple in construction and easy to assemble.

According to some embodiments of the utility model, a first spring 240 is also included. Referring to fig. 8 and 9, both ends of the first spring 240 are respectively connected to the bottoms of the first control part 120 and the second internal gear 220, and in an initial state, the first spring 240 is as shown in fig. 8, and at this time, the folder 110 may not rotate with respect to the fixed base 100; when the first control member 120 is pressed down from above, the first spring 240 is compressed as shown in fig. 9, and the folder 110 can be rotated with respect to the fixing base 100.

In this case, when the first control member 120 is pressed and then released, the "convex" portion of the third external gear 230 may not correspond to the "concave" portion of the first internal gear 210, and the third external gear 230 may be blocked by the first internal gear 210, so that the third external gear 230 may not be lifted, and therefore, it is necessary to continue to rotate the folder 110 by a certain angle, and the "convex" portion of the third external gear 230 may correspond to the "concave" portion of the first internal gear 210, and may be lifted. It will be appreciated that, because of the action of the first spring 240, even if the third external gear 230 cannot be raised immediately after the first control member 120 is released, the first control member 120 does not need to be pulled to be raised, and as long as the folder 110 is rotated by a certain angle, the third external gear 230 can be automatically raised to be coupled with the first internal gear 210 due to the elastic force of the first spring 240.
