The lower ends of the two sliding bars 510 are fixedly connected to a cover plate 508. Both the load box 507 and the cover plate 508 are made of acrylic material. Rotating the rotating shaft 506 inside the sliding plate 505, the rotating shaft 506 will drive the load box 507 to flip, so as to realize the multi-angle scanning and imaging work of the objects inside the load box 507. A connecting block 502 is fixedly connected to the surface of the limit plate 501. A lead screw 504 is threadedly connected inside the sliding plate 505. The lower end of the lead screw 504 is rotatably connected to the connecting block 502. Rotating the lead screw 504, the lead screw 504 will rotate inside the connecting block 502. At this time, the driving work of the sliding plate 505 inside the chute 503 can be realized.

[0032] A plurality of card slots 515 are evenly provided on the side wall of the rotating shaft 506. A rectangular block 512 is fixedly connected to the surface of the sliding plate 505. A card frame 513 is slidably connected inside the rectangular block 512. The size of the card frame 513 is adapted to the size of the card slots 515. The card frame 513 is stuck inside the corresponding card slots 515 on the rotating shaft 506. At this time, the locking work of the position of the rotating shaft 506 after rotation can be realized.

[0033] A first spring 514 is fixedly connected between the card frame 513 and the rectangular block 512. The card frame 513 will be stuck inside the corresponding card slots 515 on the rotating shaft 506 under the elastic force of the first spring 514.
