Finally, the engaging member 40 is pushed to engage the SIM card 50 in the slot 444 of the engaging member 40, and the protrusion 446 on the engaging member 40 is interference-fitted with the limiting slot 244 of the receiving portion 20. At this time, the end portion of the elastic hook 422 of the engaging member 40 is elastically deformed and abuts against the side wall of the engaging portion 34. So far, the SIM card 50 is firmly fixed in the housing portion 20.

The SIM card fixing device 100 is abutted against the side wall of the engaging portion 34 of the rotating member 30 by the elastic hook 422 of the engaging member 40, and is engaged with the SIM card 50 by the slot 444 of the engaging member 40. The SIM card 50 is permanently fixed in the accommodating portion 20, so that the thief cannot steal the SIM card 50 after stealing the mobile phone, so that the lost person can track the lost mobile phone. Therefore, the SIM card fixing device 100 described above has an anti-theft function, and has a simple structure and convenient operation.

It can be understood that the accommodating portion 20 can omit the first side wall 22, and at this time, the second side walls 24 are connected in a "V" shape, and the fixing groove 222 can be formed at the joint of the two second side walls 24 and toward the two second side walls 24. extend. One end of the rotating member 30 can also be provided with a rotating shaft. The two opposite side walls 24 of the receiving portion 20 are correspondingly provided with a shaft hole, and the rotating shaft passes through the shaft hole, so that the rotating member 30 is rotatably disposed on the opposite side of the receiving portion 20. Between the two side walls 24. In addition, the rotating member 30 can be coupled to the first side wall 22 by a hinge to rotate the rotating member 30 relative to the first side wall 22. The two sides of the second plate body 44 of the engaging member 20 can also respectively define a limiting slot. The two opposite side walls 24 of the receiving portion 20 respectively have corresponding limiting protrusions that cooperate with the limiting slot. In addition, the limiting protrusion 446 of the engaging member 40 and the limiting groove 244 of the receiving portion 20 may be omitted, and the second plate body 44 of the engaging member 40 may not be perpendicular to the first plate 42 of the engaging member 40. The SIM card 50 can be held in the card slot 444 of the second board 44. The second plate body 44 of the engaging member 40 may not be provided with a convex portion 442. At this time, the locking groove 444 is directly formed on the side wall of the second plate body 44 opposite to the elastic hook 422 of the first plate body 42. The engaging portion 34 is not limited to the engaging hole formed in the middle of the flat body 32, and may be other structures. The structure only needs to be able to be engaged with the end of the elastic hook 422 of the engaging member 20, for example, a card.
