When the operation is performed, the detecting block 26 contacts the memory card block 12 on the upper side of the rotating plate 58 and detects the memory card 74, when a certain memory card 74 in the memory card block 12 is detected to be qualified, the detecting magnetic block 27 on the upper side of the memory card 74 is energized and magnetized, so that the passive block 71 on the lower side of the detecting magnetic block 27 is sucked upwards, the two cutting blocks 62 on the right side of the passive block 71 are pulled leftwards by pulling the two cutting pull ropes 67, the cutting spring 66 is pulled, because the elastic force of the braking spring 69 is greater than the torsion force of the rotating torsion spring 68, the cutting knife block 65 rotates ninety degrees around the rotating shaft 64, so that the cutting knife block 65 is abutted against the inner wall of the center of the rotating cavity 63 far away from the operating cavity 23, at this time, the braking spring 69 is pulled, the rotated cutting knife block 65 moves towards the direction close to the center of the operating cavity 23, and the connecting blocks 75 on the front side and the back side of the corresponding memory card 74 are cut during the moving process, so that the memory card 74 cannot be connected to the memory card block 12 through the connecting block 75, and the corresponding qualified memory card 74 falls down onto the lower inner wall of the operating cavity 23 under the influence of gravity, thereby achieving the effect of automatically taking down the qualified memory card 74.

When the detection is finished, the electric telescopic rod 24 is controlled to contract upwards, so that the telescopic block 25 is driven to move upwards, so that the telescopic block 25 does not restrict the trigger block 29, so that the restricting spring 42 is not restricted to be reset, the restricting block 41 is pushed to the right, so that the detecting block 26 and the detecting magnetic block 27 move upward along with the telescopic block 25, the brake wheel 51 is driven to rotate during the upward movement of the telescopic block 25, so that the brake shaft 50 is rotated and the limit rope 39 and the brake rope 52 are wound around the brake shaft 50, by pulling the brake cable 52, the rotating torsion spring 59 is twisted, so that the rotating shaft 57 and the rotating plate 58 are rotated clockwise, the memory card block 12 on the upper side of the rotating plate 58 slides down along the upper end face of the rotating plate 58 and enters the recycling cavity 72, and at this time, the memory cards 74 retained on the memory card block 12 are all unqualified products, so that the functions of automatically detecting whether the memory cards 74 are qualified and classifying the memory cards are achieved.

The limiting spring 38 is compressed by pulling the limiting pull rope 39, so that the limiting rod 47, the transmission wheel 34 and six transmission plates 35 are pulled forwards, the transmission plates 35 are positioned in the exhaust cavity 31, the limiting rod 47 moves forwards to enable the limiting block 41 to be clamped in the limiting groove 48 and limit the limiting rod 47 to move backwards, the expansion block 25 continues to move upwards without contacting with the brake wheel 51, so that the brake pull rope 52 is not limited, the rotating torsion spring 59 is reset, the rotating shaft 57 and the rotating plate 58 rotate to the initial position, the expansion block 25 moves towards the initial position to enable air in the operation cavity 23 to be exhausted through the exhaust cavity 31, the tooth transmission plate 35 is positioned in the exhaust cavity 31, the transmission plate 35 is driven to rotate, the transmission wheel 34, the transmission shaft 33 and the linkage wheel 43 are driven to rotate, the linkage wheel 43 rotates to drive the driven wheel 45 to rotate, so that the driven shaft 44 rotates and winds the two driven pull ropes 46 on the driven shaft 44, the two adjusting springs 55 are compressed, the two adjusting blocks 54 are pulled forward away from the center of the operation cavity 23, the transmission shaft 33 rotates to wind the feeding pull rope 16 on the transmission shaft 33, the feeding spring 15 is compressed by pulling the feeding pull rope 16, the feeding block 14 is pulled leftward, the memory card block 12 at the lowest side in the storage cavity 11 is pushed leftward by the feeding block 14, the touch block 18 is not limited by the feeding block 14, the clamping spring 22 is reset, the clamping block 21 is pushed leftward and limits the memory card block 12 to fall under the gravity, and the memory card block 12 at the lowest side in the storage cavity 11 is pushed leftward to the upper side of the rotating plate 58, so that the automatic feeding effect is achieved.

At this time, the electric telescopic rod 24 is controlled to move downwards, so that the air flow enters the operation cavity 23 from the outside through the exhaust cavity 31, so that the transmission plate 35, the transmission wheel 34 and the transmission shaft 33 are driven to rotate reversely, the feeding spring 15 is reset, the feeding block 14 is pushed to the right to the initial position, the touch block 18 is pushed to the initial position by the feeding block 14, by pulling the trigger pull rope 19, the blocking spring 22 is compressed, the blocking block 21 is pulled to the right to the initial position, so that the position-locking block 21 no longer limits the memory card block 12, the memory card block 12 at the lowest side in the storage cavity 11 falls on the lower inner wall of the storage cavity 11, the linkage wheel 43 drives the driven wheel 45 to rotate reversely, the two adjusting springs 55 are reset, the two adjusting blocks 54 are pushed to the initial position, and the memory card assembly 12 on the upper side of the rotating plate 58 is righted by the two adjusting blocks 54, so that the effects of adjusting the position of the memory card assembly 12 and resetting the device are achieved.
