[0048] The shell 100 includes a bottom wall 150 and a first side wall 110, a second side wall 120 and a third side wall 130 which are arranged on the bottom wall 150 and connected in sequence. The first side wall 110 and the third side wall 130 are arranged at intervals in the width direction of the shell 100. The second side wall 120 is provided with a plurality of first openings 101. The first side wall 110 and the third side wall 130 are both provided with a first connecting portion 104 and a first abutting portion 103.

[0049] In detail, the first connecting portion 104 and the first abutting portion 103 are provided on the inner side of the first side wall 110, and the first connecting portion 104 and the first abutting portion 103 are arranged along the length direction of the shell 100. The first connecting portion 104 and the first abutting portion 103 are also provided on the inner side of the second side wall 120, and the first connecting portion 104 and the first abutting portion 103 are arranged at intervals along the length direction of the shell 100, wherein the length direction of the shell 100 is perpendicular to the width direction of the shell 100.

[0050] The cover body 200 is covered on the shell 100, and the second connecting portion 210 and the second abutting portion 220 are provided on both sides of the cover body 200 along its own width direction. The second connecting portion 210 is detachably connected to the first connecting portion 104, and the second abutting portion 220 abuts against the first abutting portion 103.
