[0010] When the blade tongue lock is in a locked state, the lock tongue piece simultaneously blocks the plug-in interface card slot and the limiter.

[0011] In the above scheme, when locking is required, the blade is rotated to turn the tongue lock, and the lock tongue piece rotates accordingly and finally blocks the plug-in interface card slot and the limiter at the same time, so that the plug-in interface card slot and the limiter are blocked at the same time, and the TF card cannot be plugged in or out, and the bottom shell and the upper shell cannot be disassembled. The TF card can be effectively protected, and the risk of TF card data being stolen and the chassis or product being manually disassembled / secretly stolen can be reduced; while at a low cost, physical security (secondary) protection can be effectively achieved. At the same time, the utility model has the advantages of low cost, easy and simple operation, simple structure, and easy assembly. It is easy to promote and mass-produce, and can effectively improve product mass production efficiency and product protection safety.

[0012] Preferably, the bottom shell and the upper shell are provided with mutually matching guide grooves for realizing a detachable connection.
