[0038] The technical solution of the present utility model is that the frame body 10 of the mobile phone expansion frame 100 is composed of a first main body part 11 and a second main body part 12 which are separately arranged, and the first connection end of the first main body part 11 and the second connection end of the second main body part 12 can be detachably connected by a snap-fit manner. When it is necessary to assemble the mobile phone expansion frame 100 to the mobile phone, the first main body part 11 and the second main body part 12 can be respectively arranged at both ends of the mobile phone, and then the two are assembled into one body, so that the first clamping end of the first main body part 11 and the second clamping end of the second main body part 12 can respectively clamp the opposite ends of the mobile phone, and thus the frame body 10 and the mobile phone can be closely fitted, thereby improving the assembly convenience of the mobile phone expansion frame 100.

[0039] Please refer to Figures 2 to 4 , in the embodiment of the present utility model, the first connection end and the second connection end are connected by snap-fit, one of the first connection end and the second connection end is provided with a card slot 111, a notch 111a is formed in the slot wall of the card slot 111, and the other is movably provided with a card block 121, and a convex block 121a is arranged on one side of the card block 121;

[0040] The card block 121 has a locking position and an unlocking position in the moving stroke. When the card block 121 is in the locking position, the convex block 121a is inserted into the notch 111a, so that the card block 121 is locked in the card slot 111. When the card block 121 is in the unlocking position, the convex block 121a is separated from the notch 111a, so that the card block 121 can enter and exit the card slot 111.

[0041] In this way, the detachable connection between the first main body part 11 and the second main body part 12 can be realized through the mutual snap-fit of the card block 121 and the card slot 111.

[0042] In some embodiments, both the card slot 111 and the card block 121 are arranged on the inner side of the frame body 10. In this way, after the frame body 10 is assembled to the mobile phone, the inner side of the frame body 10 can be attached to the back cover of the mobile phone, so that the snap-fit structure formed by the foregoing card slot 111 and the card block 121 can be hidden inside, thereby avoiding affecting the appearance consistency of the mobile phone expansion frame 100. Further, a lock release groove can be formed on the outer side of the frame body 10, and at least a part of the card block 121 penetrates from the inner side of the frame body 10 to the outer side of the frame body 10 and is exposed in the lock release groove. In this way, the user can directly drive the card block 121 to move so that it correspondingly moves to the locking position or the unlocking position, which is beneficial to improving the use convenience of the mobile phone expansion frame 100.

[0043] Please refer to Figures 1 to 4, in an embodiment of the present utility model, the second connection end is provided with an installation groove 122, the clamping block 121 is movably arranged in the installation groove 122 and protrudes from the notch of the installation groove 122;
