In the embodiment, the limiting piece 40 extends from one side wall of the receiving portion 30 to the opposite side wall, so that the limiting piece 40 and the receiving portion 30 form a cavity having an opening. The SIM card 20 can be positioned within the volume.

Referring to FIG. 6 , the elastic pressing member 50 includes a fixing portion 52 , an elastic portion 54 , and a limiting portion 56 . Both ends of the elastic portion 54 are respectively connected to the fixing portion 52 and the limiting portion 56 to form a "U" shape. In the present embodiment, the elastic pressing member 50 is an integrally formed structure, and the fixing portion 52 and the limiting portion 56 are respectively formed to extend outward from both ends of the elastic portion 54 and are respectively bent toward both sides of the elastic portion 54. The fixing portion 52 has a rectangular sheet-like structure, and a fixing hole 521 is opened in a middle portion thereof. The fixing post 161 is inserted into the fixing hole 521 to fix the elastic pressing member 50. The elastic portion 54 is provided with a resisting portion 541. The abutting portion 541 extends from one side of the elastic portion 54 to the opposite side to form a sleeve-like structure. The abutting portion 541 is for resisting the battery 14. The limiting portion 56 includes a connecting body 561 and a hook 563. The connecting body 561 is connected to one end of the elastic portion 54 opposite to the fixing portion 52. The hook 563 is bent from one side of the free end of the connecting body 561 Extend to form an "L" shape. The hook 563 extends into the inlet end 34 of the receiving portion 30 and catches the end portion 22 of the SIM card 20, so that the SIM card 20 is fixed in the receiving portion 30.

Referring to FIG. 4 and FIG. 7 simultaneously, when the SIM card 20 is mounted, first, the SIM card 20 is received from the inlet end 34 of the accommodating portion 30 in the accommodating portion 30, so that the IC chip 22 of the SIM card 20 and the accommodating portion 30 are The conductive contacts 322 are electrically connected. Then, the battery 14 is placed in the battery receiving portion 12, and the side wall of the battery 14 is abutted against the abutting portion 541 of the elastic pressing member 50, so that the elastic portion 54 of the elastic pressing member 50 is elastically deformed and elastic. The hook 563 of the limiting portion 56 of the holding member 50 is engaged with the end portion 22 of the SIM card 20, and finally the SIM card 20 is firmly fixed to the receiving portion 30.

Referring to FIG. 4 and FIG. 8 simultaneously, when the SIM card 20 is detached, first, the battery 14 is taken out from the battery accommodating portion 12, and the side wall of the battery 14 is separated from the abutting portion 541 of the elastic pressing portion 50, thereby elastically pressing. The elastic portion 54 of the holding member 50 is restored to deform so that the hook 563 of the limiting portion 56 of the elastic holding member 50 is separated from the end portion of the SIM card 20. Then, the SIM card 20 can be taken out from the accommodating portion 30.

The SIM card fixing device 100 is held by the end of the SIM card 20 by the hook 563 of the elastic holding member 50, thereby firmly fixing the SIM card 20 in the accommodating portion 30. Moreover, by controlling the deformation and recovery of the elastic pressing member 50, the SIM card 20 is fixed or detached, so that the SIM card 20 can be easily attached and detached. In addition, the battery 14 is abutted against the abutting portion 541 of the elastic pressing member 50, so that the SIM card 20 needs to be taken out from the battery receiving portion 12 when disassembling, so as to avoid taking out the SIM without powering off. The card 20 extends the life of the electronic device and the SIM card 20.

Referring to FIG. 9, the SIM card fixing device according to Embodiment 2 of the present invention is similar to the SIM card fixing device 100 of Embodiment 1, and is different in the elastic pressing member 60. The elastic pressing member 60 includes a fixing portion 62, an elastic portion 64, and a limiting portion 66. Fixing portion 62 and limiting portion 66 are respectively formed to extend outward from both ends of the elastic portion 64, and are respectively bent toward one side of the elastic portion 64, and the degree of bending is slightly different. The fixing portion 62 has a rectangular sheet-like structure, and a fixing hole 621 is opened in a middle portion thereof. A pressing portion 641 extends outwardly from one side of the elastic portion 64. The limiting portion 66 includes a connecting body 661 and a hook 663. The hook 663 is bent and extended from one side of the free end of the connecting body 661 to form an "L" shape.

When the SIM card 20 is fixed, first, the pressing portion 641 is pulled to elastically deform the elastic portion 64; then, the SIM card 20 is placed in the accommodating portion 30; finally, the pressing portion 641 is loosened to elasticize the elastic portion 64 to be restored. The deformation is such that the hook 663 of the limiting portion 66 is engaged with the end of the SIM card 20, and finally the SIM card 20 is firmly fixed in the receiving portion 30. When the SIM card 20 is detached, first, the pressing portion 641 is pulled to elastically deform the elastic portion 64, thereby separating the hook 663 of the limiting portion 66 from the SIM card 20; and then, the SIM card 20 is taken out from the accommodating portion 30.

It can be understood that the elastic pressing members 50 and 60 are not limited to be engaged with the fixing posts 161 of the accommodating groove 16 by the fixing holes 521 and 621, and the elastic pressing members 50 and 60 are fixed to the side walls of the accommodating groove 16, It can also be fixed to the side wall of the accommodating groove 16 by other means.
