When the built-in antenna needs to be repaired, the push plate is pushed by hand, and the connecting spring is compressed when the push plate moves, and the card block is separated from the card slot. At this time, the inspection cover can be taken out from the inspection port, and then the lifting plate can be taken out, which is convenient for the inspection of the antenna installed on the lifting plate, thereby improving the convenience of maintenance.

[0022] The present invention is further configured such that a plurality of equally spaced flow holes are provided on the top of the lifting plate, and the cross-section of the flow holes is an isosceles trapezoidal structure.

[0023] Through the above technical solution: the provision of the flow holes can strengthen the air flow between the partition and the shell, further improving the heat dissipation effect.
