In addition, the push plate 1-2-2-3 can return to the original position only by pushing the sample rack 5 which is detected away from the input end 1-2-1 of the recovery area 1-2 under the driving of the second motor 1-2-2-1 and the eccentric wheel 1-2-2, the time required by the process is short, and waiting congestion of the sample rack 5 at the back can hardly be caused.

When the sample frame 5 in the area to be detected 1-1 needs to be transferred, the third motor 1-1-4-1 controls the push claw 1-1-4-4 to move to the position below the sample frame 5, then the electromagnetic chuck 1-1-4-5 is powered off to lose magnetic force, the push claw 1-1-4-4 rotates relative to the transition plate 1-1-4-3 to enable the other end of the push claw 1-1-4-4 to penetrate through the second open slot 1-1-5 to be matched with the lower side face of the sample frame 5, then the third motor 1-1-4-1 drives the push claw 1-1-4-4 to transfer the sample frame 5 to the output end of the area to be detected 1-1, then the electromagnetic chuck 1-1-4-5 is powered on again, the push claw 1-1-4-4 is driven through magnetic force to enable the push claw 1-1-4-4 to be located below the area 1-1 again, and the third motor 1-1-4-1 controls the push claw 1-1-4-4 to return to the initial position.
When the structure is used, 4 push claws 1-1-4-4 can be designed to be evenly distributed on two sides of the sample rack 5, and the structure can ensure the stability of the sample rack 5 in the transfer process of the area to be detected 1-1. The upper end face of the push claw 1-1-4-4 can also be designed into a structural form with a groove, the width of the groove is slightly larger than that of the sample rack 5, and the lower part of the sample rack 5 is matched with the groove, so that the stability of the sample rack 5 in the transfer process of the area to be detected 1-1 can also be improved.
