Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIG. 1 and FIG. 2 , the present invention provides a technical solution: a mobile Internet access device, comprising a housing 1 , a first opening 5 is provided on the right side of the housing 1 , and a second opening 5 is provided on the top of the housing 1 . Opening 6, the housing 1 is provided with a support plate 2, the right end of the support plate 2 is fixed with a USB plug 3, the right end of the USB plug 3 is facing the first opening 5, and the left side of the bottom surface of the support plate 2 is fixed with a sliding Block 13, the inner wall of the casing 1 is provided with a chute 12 that matches the sliding block 13, so as to facilitate the movable connection between the casing 1 and the support plate 2, and the circuit board 7 is fixed on the top surface of the support plate 2, so A NANO SIM card slot 8 is arranged in the middle of the circuit board 7, a protective cover 9 is arranged on the left side of the NANO SIM card slot 8, a wireless antenna 10 and a microcontroller unit 11 are arranged on the left side of the circuit board 7, and the Rubber ears 14 are fixed on both sides of the right end of the support plate 2, a push rod 4 is fixed at the top of the support plate 2, one end of the push rod 4 passes through the second opening 6, and the circuit board 7 is fixed with a SIM card function.
