During the detection of the SD card, the mounting seat with the SD card is inserted into the through hole of the jig by pressing down the lower pressing plate, and then the pressing is continued so that the through hole on the jig is penetrated by the fixed pin and connected with the mounting seat with the SD card for testing. At this time, the testing of the SD card is realized through the circuit inside the body; a buffer component is also arranged between the body and the jig, and the buffer component includes a spring, and the spring is not in contact with the pins.

The buffer assembly also includes a guide column fixed at the edge of the bottom end surface of the fixture, and the guide column is inserted into the through hole. A sealing ring is also sleeved on the surface of the guide column, and the sealing ring is against the through hole. When the guide column descends, the air inside the through hole can be directly discharged from the air hole. Since the diameter of the air hole is fixed, the amount of discharged gas will also be quantitatively discharged when it reaches the maximum value. Therefore, when the spring is compressed and rebounded, constant speed adjustment can be achieved to avoid pressing down and rebounding too quickly to affect the stability of the connection between the SD card mounting seat and the through hole.

[0007] Preferably, annular grooves are equidistantly formed on the bottom surface of the guide column, the sealing ring is inserted into the annular groove, and the thickness of the sealing ring is greater than the inner depth of the annular groove.

[0008] Preferably, mounting frames are installed on both sides of the rear surface of the lower pressure plate, and walking wheels are installed on the mounting frames.
