When the memory card a needs to be pulled out, the pressing beam 531 of the stopper 50 is pressed downward, so that the pressing end portions 532 at the two lateral ends of the pressing beam 531 press the pair of inclined arms 521 downward to move the stopper end 522 downward to below the bottom surface of the front end portion a1 of the memory card a, and simultaneously, the front end portion a1 of the memory card a is manually pulled forward to move the front end portion a1 to above the stopper end 522, and the memory card a is pulled out forward.
The slider 30 is used for limiting the two transverse sides of the memory card a in the insertion and extraction process, and continuously limiting the memory card a in the sliding process.
