[0002] Most of the common luggage on the market is hard-shell luggage, which is large in volume and has a certain weight by itself, and its expandability is relatively limited. Compared with hard-shell luggage, soft-shell luggage made of materials such as cloth as the outer shell has a large extensibility in volume and is light in weight, making it easy to carry and handle. However, the stability of its structure is relatively low. When the soft-shell luggage is pushed on an uneven ground or a ground with greater resistance, the flexible box body may twist due to the resistance, making it difficult to push smoothly. Summary of the Utility Model

[0008] The other end of the support rod is connected to one end of the short side of the lower tray and is far away from the pull rod.

[0009] The inclined support structure further includes a first connecting piece and a second connecting piece. The first connecting piece is arranged on the left and right sides of the upper tray, the second connecting piece is arranged on the left and right sides of the lower tray, and the upper and lower ends of the support rod are respectively inserted into the first connecting piece and the second connecting piece.

[0010] The first connecting member includes a first connecting plate and a first slot. A plurality of first connecting holes are provided on the first connecting plate, and upper tray connecting holes corresponding to the first connecting holes are provided on the upper tray. The first connecting plate and the upper tray are connected by the first connecting holes, the upper tray connecting holes and screws. One end of the pull rod can be inserted into the first slot;

[0011] The second connecting member includes a second connecting plate and a second slot. A plurality of second connecting holes are provided on the second connecting plate, and lower tray connecting holes corresponding to the second connecting holes are provided on the lower tray. The second connecting plate and the lower tray are connected by the second connecting holes, the lower tray connecting holes and screws. The other end of the pull rod can be inserted into the second slot.

[0012] The first connecting member includes a first insertion cylinder, and the first slot is located inside the first insertion cylinder;

[0013] The second connecting member includes a second insertion cylinder, and the second slot is located inside the second insertion cylinder.
