So configured, when the two seat frames 3 are respectively connected to the two side frames 1, the seat 200 is in an orientation state relative to the frame 100; the two seat frames 3 are detached from the brackets 1 at the two sides and then are reversed front and back, and then the two seat frames 3 which are reversed front and back are assembled to the side brackets 1 at the corresponding sides, so that the front and back reversing arrangement of the seat 200 relative to the frame 100 can be realized, namely the seat 200 can be switched between the front arrangement and the back arrangement relative to the frame 100, and the children can be conveniently looked up; and no matter the seat 200 is arranged forward or backward relative to the frame 100, the second connecting device is arranged between the left and right seat frames 3, that is, no matter the seat 200 is arranged forward or backward relative to the frame 100, the second connecting device can allow the two seat frames 3 to move between relatively close and relatively far away, so that when the frame is folded and the left and right side supports 1 are relatively close, the two seat frames 3 respectively connected with the two side supports 1 can be close together therewith, and when the frame is unfolded and the left and right side supports 1 are relatively far away, the two seat frames 3 respectively connected with the two side supports 1 can be far away together therewith, that is, the left and right seat frames 3 can be relatively close to/far away along with the relatively close/far away of the left and right side supports 1. Therefore, no matter the seat 200 is arranged forward or backward relative to the frame 100, when the frame is folded/unfolded, the seat does not need to be detached, and the seat does not need to be adjusted to a specific orientation, so that the utility model discloses the folding/unfolding operation of the whole body of the stroller is very simple and convenient, and because of folding back, the two side supports 1 are relatively close to, the two seat frames 3 are also relatively close to, thereby the whole volume of the stroller after folding is very small, and is convenient for storing and carrying.

Each seat frame 3 comprises a supporting member 31, and the supporting member 31 is configured to be detachably connected with one side frame 1, and is detachably connected with the other side frame 1 after being turned back and forth. That is, the seat frame is connected to the side frames 1 through the supporting frames 31, when the seat 200 is arranged in the front direction, the left supporting member 31 is detachably connected to the left side frame 1, and the right supporting member 31 is detachably connected to the right side frame 1; when the seat 200 is installed backward, the original left side support 31 is turned forward and backward and then detachably connected to the right side bracket 1, and the original right side support 31 is turned forward and backward and then detachably connected to the left side bracket 1. In this manner, the seat 200 is convertible between a forward and rearward disposition relative to the frame 100.

The second connecting means includes a support member connecting means 41 provided between the two support members 31, and the support member connecting means 41 is provided to allow the left and right support members 31 to move between relatively close to and relatively far from each other. So that when the left and right side frames 1 relatively approach/move away, the two supporting members 31 relatively approach/move away together.

In this embodiment, the supporting member connecting device 41 includes two first seat linkage rods 411 and two second seat linkage rods 412 that are cross-pivoted, one side of each of the two first seat linkage rods 411 is respectively pivoted to the two left and right supporting members 31, the other side of each of the two second seat linkage rods 412 is also respectively pivoted to the two left and right supporting members 31, and the pivoting positions of one of the supporting members 31 and the first seat linkage rods 411 and the pivoting positions of the supporting members 31 and the second seat linkage rods 412 are arranged at intervals in the front-back direction; the other side of the first seat linkage rod 411 pivotally connected to the left side supporting member 31 is pivotally connected to the left side of the right side second seat linkage rod 412, and the other side of the first seat linkage rod 411 pivotally connected to the right side supporting member 31 is pivotally connected to the right side of the left side second seat linkage rod 412 (as shown in fig. 2, 3 and 4).
