The first upper attaching portion 16 is located above the first middle attaching portion 13 and can be arranged at an obtuse angle with the first middle attaching portion 13, that is, the cross section of the assembling opening 12 can be trapezoidal, the assembling of the assembling shell 20 can be facilitated by the structure, and the structure can be understood as that the base shell 10 is of a U-shaped appearance structure.

In addition, referring to fig. 3, the first lower abutment 15 and the first upper abutment 16 may be complete abutment planes.

In some embodiments, the first middle attaching part 13 may have a structure as shown in fig. 3. Referring to fig. 3, the first intermediate bonding portion 13 includes two straight bonding edges 131 integrally connected with the base case 10, the two straight bonding edges 131 are parallel and spaced apart, and each straight bonding edge 131 is disposed along the spacing direction of the first upper bonding portion 16 and the first lower bonding portion.

The first middle laminating portion 13 comprises two straight line laminating strakes 131, can guarantee the butt joint or the connection with the middle laminating portion 21 of second, and the setting of two straight line laminating strakes 131 also guarantees the passageway that forms inner chamber 11 and assemble opening 12 intercommunication between the two simultaneously, guarantees the installation of inside spare part.

It should be noted that, along the direction of the interval between the two straight line attaching edges 131, the base case 10 has two outer side walls, and the two straight line attaching edges 131 may be integrally connected with the two outer side walls, or may be directly bent from the two outer side walls.

In some embodiments, the arcuate portion 14 may be configured as shown in fig. 3. Referring to fig. 3, two arc-shaped portions 14 are provided, the two arc-shaped portions 14 are respectively located at two ends of the first middle attaching portion 13, and the two arc-shaped portions 14 are used for enabling the first middle attaching portion 13 to be respectively connected with the first lower attaching portion 15 and the first upper attaching portion 16.

Because the arrangement of the first upper attaching portion 16 and the first lower attaching portion 15 is involved, the two arc portions 14 can ensure smooth transition connection between the first middle attaching portion 13 and the first upper attaching portion 16 and the first lower attaching portion 15, respectively, and can ensure the attractive effect of external viewing.

Wherein, each arc-shaped part 14 is provided with a socket 141 for inserting the sharp corner 22 in the assembled shell 20, and arc-shaped edges 142 are formed at two ends of the socket 141. The socket 141 can also be communicated with the inner cavity 11 and the assembly opening 12, so that the sharp corner 22 on the assembly shell 20 can be inserted into the inner cavity 11 and hidden in the inner cavity 11, the mode of attaching two arc segments in the past is changed, and the effect of perfectly attaching the arc segments can be observed outside.

In this embodiment, since the pointed portion 22 of the assembled housing 20 extends into the inner cavity 11, the arcuate sides 142 formed at both ends of the insertion opening 141 are required to have a length equal to or greater than the width of the assembled housing 20. Of course, it should be specifically understood that the two arcuate edges 142 are formed on two outer sidewalls of the base shell 10 in the spacing direction of the two straight line attaching edges 131, and the spacing length of the inner wall surfaces of the two outer sidewalls is greater than or equal to the width of the assembled shell 20, so as to ensure that the sharp corner 22 of the assembled shell 20 can extend into the two outer sidewalls.
