When the magnetically permeable top cover 120 is covered on the magnetically permeable bottom cover 110, the top side wall 121 is connected to the edge of the magnetic bottom cover 110 to form a peripheral wall 180; the top side wall 121 is provided with a gap 160. When the magnetic top cover 120 is closed on the bottom cover 110, the accommodating cavity 170 communicates with the outside through the gap 160 . Specifically, the plate surfaces of the magnetic bottom cover 110 and the top cover 120 are rectangular, and the four side edges of the top cover 120 each have a top side wall 121 extending downward, and four top side walls 121 The height of the top side wall 121 is located at the four corners of the magnetic top cover 120. A notch 160 is provided. When the magnetic top cover 120 is closed on the bottom 110, the end surface of the top side wall 121 It is attached to the plate surface of the magnetic bottom cover 110, the top side wall 121 is the peripheral wall 180, and the connecting frame 420 can pass through the gap 160.
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。The above are only the embodiments of the present invention.
