Technical Field

[0001] The utility model relates to the technical field of TF cards, in particular to a drawer-type TF card holder with a detection shrapnel structure. Background Art

[0002] TF card is a very small flash memory card, and its format originated from SanDisk. Originally, this memory card was called T-Flash, and later changed to Trans Flash. The reason for renaming it to Micro SD is because it was adopted by the SD Association. Other memory cards adopted by SDA include Mini SD and SD cards. It is mainly used in mobile phones, but due to its small size and continuous improvement in storage capacity, it has been used in GPS devices, portable music players and some flash memory disks.

[0011] Furthermore, the positioning rod and the positioning hole are clearance-matched, and the telescopic rod is composed of a sleeve and a moving rod. One end of the moving rod passes through and extends to the interior of the sleeve, and the outer side of the moving rod is fixedly connected to a limiting block located inside the sleeve, and a through hole adapted to the moving rod is opened on one side of the sleeve.

[0012] Furthermore, the limiting assembly includes two support blocks, which are respectively fixedly connected to the front and back of the mounting plate.
