The receiving slot 117 is disposed corresponding to a subscriber identity card connector (not shown) on a circuit board in the mobile phone, and has a shape and a size substantially equivalent to the subscriber identity card 20 for receiving the subscriber identity card 20 therein. The receiving groove 117 is formed adjacent to the lower wall 112 with a slanted wall 118 for cooperating with the bevel 21 of the user identification card 20 to prevent the user identification card 20 from being reversely inserted. The first side wall 113 protrudes toward the one side of the receiving groove 117 by a shape of the first block 119. The receiving groove 117 is provided with a mounting portion 1171 on one side of the first block 119 for mounting the rotating shaft 13 therein.

Referring to FIG. 5 and FIG. 6 , the cover body 12 is substantially an “L”-shaped sheet body, and includes a pressing portion 121 , a fastening portion 122 , and a connecting portion of the pressing portion 121 and the fastening portion. The connection portion 123 of 122.

A shaft barrel 1211 is disposed at one end of the nip portion 121 away from the connecting portion 123. The rotating shaft barrel 1211 accommodates the rotating shaft 13 therein in a relatively rotatable manner. The nip portion 121 has a rectangular opening 1212 corresponding to the user identification card connector, so that the nip portion 121 is directly pressed against the user identification card connector.

The fastening portion 122 is disposed at a distal end of the connecting portion 123 to provide a rib 1221 for the user to rotate the cover 12 around the rotating shaft 13 . A strip-shaped second block 1222 is protruded from the surface of the splicing portion 122 away from the nip portion 121, so that a card slot 1223 is formed between the rib 1221 and the second block 1222. The first block 119 is held in the card slot 1223.

The connecting portion 123 is substantially an "L"-shaped elastic sheet body having a first sheet body 1231 and a second sheet body 1232 vertically connected to the first sheet body 1231.

Referring to FIG. 5 and FIG. 6 , when the second block 1222 of the fastening portion 122 is engaged and disengaged from the first block 119 , the cover 12 needs to have a certain bending deformation. According to physical knowledge, the entire cover is known. The maximum surface bending stress of the body 12 occurs at the junction 14 of the connecting portion 123 and the fastening portion 122. It is known that the greater the angle θ at which the fastening portion 122 rotates about the joint 14, the greater the surface bending stress of the joint 14. The wafer card holding structure 10 increases the rotational force arm d of the fastening portion 122 by using the connecting portion 123, so that the fastening portion 122 only needs to rotate a small angle θ to realize the second card 1222 and the first card. The snapping of the block 119 greatly weakens the surface bending stress of the joint 14, and prevents the cover 12 from being broken due to excessive surface bending stress.

It can be understood that the first piece 1231 and the second piece 1232 can also be connected at an obtuse or acute angle, that is, the angle between the first piece 1231 and the second piece 1232 is less than 180°.

It can be understood that the first piece 1231 and the nip 121 can also be connected at an obtuse or acute angle, that is, the angle between the first piece 1231 and the second piece 1232 is less than 180°.

It can be understood that the second piece 1232 and the fastening portion 122 can also be connected at an obtuse or acute angle, that is, the angle between the first piece 1231 and the second piece 1232 is less than 180°.

The wafer card holding structure 10 is connected to the pressing portion 121 and the fastening portion 122 by the reversely bent connecting portion 123, and the length of the rotating force arm d is increased when the thickness of the body 11 is constant. The bending deformation of the fastening portion 122 is greatly reduced, so that the surface stress of the joint portion 14 is greatly weakened, thereby preventing the cover body 12 from being broken due to excessive stress. In addition, the chip card holding structure 10 is reversely punched out of the second card block 1222 to be engaged with the first card block 119, thereby avoiding direct wear of the body 11.
