The rear support connecting rod assembly 5 is rotatably mounted on shaft 7 25. The rear support cross brace assembly 6 is rotatably connected to the rear support assembly 4 via shaft 13 31. The rear support assembly 4 is rotatably mounted on shaft 8 26. The middle push rod assembly 2 is mounted on shaft 9 27. The armrest assembly 11 is mounted on shaft 10 28. The armrest assembly 11 is mounted on shaft 10 28. The upper push rod assembly 1, the middle push rod assembly 2 and the front support assembly 3 form a three-section telescopic structure. When the rear support assembly 4 folds and moves closer to the front support assembly 3, the left and right parts of the rear support assembly 4 move closer to the center plane at the same time.

[0026] As a preferred technical solution of this utility model, the bottom of the suitcase is symmetrically provided with universal wheels 14 on one side, and the bottom of the suitcase is provided with a mounting groove that cooperates with the front wheel assembly connector 7 on the other side, and the mounting groove is symmetrically provided with protrusions 15. The upper side wall of the suitcase is provided with a locking hook 16 that cooperates with the front bracket assembly 3.

[0027] As a preferred technical solution of this utility model, the front wheel joint assembly 7 includes a locking member 18, which is installed in cooperation with the shaft 23 through a return torsion spring. The side wall of the locking member 18 is provided with a groove 17 that is installed in cooperation with the protrusion 15. By locking the locking member 18 in the front wheel joint assembly 7 into the front support assembly 3, when the suitcase is removed from the stroller, the front wheel joint assembly 7 returns to its original position and is locked in the front support assembly 3 under the action of the return torsion spring. At this time, the shaft 23 is perpendicular to the ground, and the front wheel serves as the universal wheel of the stroller.

[0028] As a preferred technical solution of this utility model, the rear support cross brace assembly 6 includes two rear support cross braces 601 and a rear support cross brace joint 602. The two rear support cross braces 601 are rotatably installed through the cooperation of shaft 12 30 and the rear support cross brace joint 602.

[0030] The working principle of this utility model:

[0031] As a suitcase stroller: Align the protrusion 15 on the suitcase with the groove 17 in the front support assembly 3. This will release the lock between the front wheel joint assembly 7 and the front support assembly 3, and keep the axle 23 in the front wheel assembly 8 parallel to the axle of the suitcase's universal wheel 14. Move the suitcase towards the front support assembly 3 until the locking hook 16 on the suitcase locks the stroller. Because the suitcase and the front support assembly 3 of the stroller are parallel and at an angle to the ground, the front wheel assembly 8 in the stroller cannot rotate in all directions. Then, close the rear wheel assembly 10 in the stroller to achieve universal rotation. At this time, it can be used as a suitcase stroller for dragging or pushing, and it can be folded and unfolded as a whole.

[0032] Used as a suitcase: When the suitcase is installed on a stroller, the rear support assembly 4 is folded together with the front support assembly 3. As can be seen above, at this time, the universal wheel 14 axis 23 of the front wheel assembly 8 is parallel to the universal wheel axis in the suitcase. At this time, it can be used as a trolley case, and when used as a suitcase, the four wheels are universal.

[0033] When used as a stroller: Remove the suitcase. At this time, the front wheel joint assembly 7 returns to the locked position under the action of the return torsion spring, and the swivel wheel axis of the front wheel assembly 8 is perpendicular to the ground. At this time, the front wheel assembly 8 can swivel. Then open the rear wheel assembly 10 to orient it. At this time, the rear wheel assembly 10 cannot swivel. It can be used as a stroller on its own. It is also a foldable stroller.
