[0033] A method for using a computer graphics card plug-in and pull-out test device comprises the following steps: S1: Replace the interface unit 24 on the plug-in structure 2 according to the model of the computer graphics card, and control the L-shaped seat 23 to rise and fall to a suitable height for the interface unit 24 to be plugged into the computer graphics card through the lifting mechanism 21; S2: Insert the hexagonal wrench into the adjusting screw groove 376 and rotate it, so that the guide module composed of the trapezoidal block 371, two slides A379 and two slides B373 as a whole descends, so that the plug-in block 372 is plugged into the plug-in cavity, and the two connecting plates 351 are always in contact with the two ends of the guide module under the elastic force of the tension spring A350. The connecting plate 351 passes through the inclined surface of the trapezoidal block 371 and contacts the slide A379, so that the friction block 354 slides toward the centripetal direction of the slide groove C324 along with the installation arc block 352, causing the friction block 354 to disengage from the friction groove 315, so that the adjusting disc A32 can rotate.

[0034] S3: Control the output shaft of the motor 301 to rotate by an external control mechanism, so that the connecting shaft 302, the adjusting disc B36 and the adjusting disc A32 rotate as a whole, so that the angle of the connecting line of the two positioning shafts 344 is consistent with the diagonal angle of the computer graphics card in the correct position; S4: Insert the hexagonal wrench into the adjusting screw groove 376 and rotate it, so that the guide module rises, the plug-in block 372 is separated from the plug-in cavity, and the connecting plate 351 passes through the inclined surface of the trapezoidal block 371 and contacts the slide plate B373, so that the friction block 354 slides along the installation arc block 352 toward the eccentric direction of the slide groove C324, until the friction block 354 is squeezed and contacted with the friction groove 315, so that the adjusting disc A32 cannot rotate; S5: The computer graphics card is placed in the positioning cavity formed by the four positioning plates 346, and the output shaft of the motor 301 is controlled to rotate by an external control mechanism, so that the connecting shaft 302 and the adjusting disc A32 rotate, and the gap position between the oblique guide groove 38 and the centripetal guide groove 33 changes, so that the movable ring 39 moves on the oblique guide groove 38, and the positioning assembly 34 moves in the centripetal guide groove 33. The positioning cavity formed by the four positioning plates 346 is reduced to position the computer graphics card.
