An L-shaped lifting plate 610 is fixedly connected to the right end of the movable plate 68 and the outer end of the L-shaped lifting plate 610 is slidably connected to a first slide groove 62. Multiple third scanners 615 are evenly distributed on the lower side of the horizontal end of the L-shaped lifting plate 610.

[0022] In this embodiment, the object rotation component 4 includes a first stepper motor 41 fixedly connected to the middle of the lower end of the workbench 1. The output end of the first stepper motor 41 is fixedly connected to a first rotating shaft 42. The outer end of the first rotating shaft 42 is rotatably connected to the workbench 1 through a bearing. The upper end of the first rotating shaft 42 is fixedly connected to a disk 43.

[0023] Specifically, the object rotation component 4 can place the object on the placement disk 43. Then, the first stepper motor 41 is powered by an external power source. The output of the first stepper motor 41 drives the first rotating shaft 42 to rotate. The first rotating shaft 42 drives the placement disk 43 to rotate, which in turn drives the object to rotate, thus improving the comprehensiveness of 3D scanning.

[0024] In this embodiment, a top plate 69 is fixedly connected to the upper end of the second screw 67, and the outer diameter of the top plate 69 is larger than the outer diameter of the second screw 67.

[0034] Working principle: First, the height of the scanning adjustment component 6 can be adjusted according to the height of the object. At this time, the second stepper motor 65 can be powered by an external power source. The output end of the second stepper motor 65 drives the first screw 66 and the second screw 67 to rotate. The second screw 67 drives the top plate 69 to rotate. The first screw 66 and the second screw 67 both drive the connected moving base 613 to move upward. Each moving base 613 drives the second scanner 614 to move upward. Since the number of threaded grooves on the outer ends of the first screw 66 and the second screw 67 is different, the moving distance of the upper moving base 613 is greater than that of the lower moving base 613. At this time, the moving base 613 drives the sliding block 616 to slide in the second sliding groove 63. During the rotation of the second screw 67, the second screw 67 drives the moving plate 68 to move, and the moving plate 68 drives the L-shaped lifting plate 610 to move upward. The L-shaped lifting plate 610 slides in the first slide groove 62. Next, the object is placed on the placement disk 43. Then, the first stepper motor 41 is powered by an external power source. The output of the first stepper motor 41 drives the first rotating shaft 42 to rotate. The first rotating shaft 42 drives the placement disk 43 to rotate, which in turn drives the object to rotate. This improves the comprehensiveness of 3D scanning. This utility model enables comprehensive scanning of tall objects without the need for flipping and secondary scanning, thus improving the efficiency of 3D scanning of objects.
