The two ends of the second sidewall 112 are respectively connected to the first sidewall 111 and the third sidewall 113, forming a positioning cavity 11a. The first sidewall 111 and the third sidewall 113 are inclined towards the positioning cavity 11a. With this design, the first connecting member 11 has a simple structure and is easy to process and form. At the same time, the first sidewall 111 and the third sidewall 113 are relatively inclined, which can prevent mistakes and avoid assembly direction errors. On the other hand, it can also provide the operator with intuitive visual positioning. During the stacking and docking process, position correction can be performed to achieve accurate positioning and ensure that the upper and lower boxes 2 are flush after stacking.

[0060] The fourth sidewall 1211 is correspondingly and inclined to the first sidewall 111; the sixth sidewall 1213 is correspondingly and inclined to the third sidewall 113. It is understood that the fourth sidewall 1211 fits into the first sidewall 111, the sixth sidewall 1213 fits into the third sidewall 113, and the fourth sidewall 1211 fits into the second sidewall 112, achieving the positioning engagement between the positioning boss 121 and the positioning cavity 11a. This not only prevents incorrect assembly direction but also provides the operator with intuitive visual positioning. During the stacking and docking process, positional correction can be performed to achieve accurate positioning and ensure that the upper and lower housings 2 are flush after stacking.

[0063] like Figure 1 As shown, the first connector 11 and the second connector 12 are fixedly connected by fasteners 3 passing through the first mounting hole 112a and the second mounting hole 1212a.

[0064] It is understandable that by fastening the first connector 11 and the second connector 12 with fasteners 3, the problem of the housing 2 falling off due to the separation of the first connector 11 and the second connector 12 can be avoided.

[0065] In this embodiment, fastener 3 is a bolt.
