Moreover, the side surface of the limiting part 3125 away from the fourth frame member 22 is flush with the side surface of the second corner member 313, so that the side edges of the first corner assembly 31 are more flat.

First top corner assembly 31 and second top corner assembly 32 are similar in structure and will not be described in detail herein.

In some other embodiments, the guide portion 3122 is connected to the limit portion 3125, the guide portion 3122 is not connected to the first mating surface 3121, and a gap is provided between the guide portion 3122 and the first mating surface 3121.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the utility model, the steps may be implemented in any order, and there are many other variations of the different aspects of the utility model as described above, which are not provided in detail for the sake of brevity; while the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
