The inner wall of the bracket 2 is rotatably connected with a gravity rotation axis 3, and the function of the gravity rotation axis 3 is to carry the scanner to rotate under gravity. The bottom of the gravity rotation axis 3 is fixedly connected with a placement table 4, and the function of the placement table 4 is to place the scanner body 20. The side wall of the table 4 is fixedly connected with a fixing plate 6, and the function of the fixing plate 6 is to achieve a fixed connection to the structure. The side wall of the fixing plate 6 is fixedly connected with a spring clip 5, and the function of the spring clip 5 is to fix. One end of the spring clip 5 is fixedly connected with a clamping plate 7, and the clamping plate 7 also plays a certain fixing role. A scanner body 20 is installed on the top of the placement table 4, and the scanner body 20 performs scanning work. The side wall of the gravity rotation axis 3 is fixedly connected with a rotating disk 8 through a rotating rod to observe the rotation angle. The rotating disk 8 is parallel to the gravity rotation axis 3, and the bracket 2 is rotatably connected to the rotating disk 8. The spring clips 5 are symmetrically arranged on both sides of the placement table 4.

[0024] Reference Figure 1-Figure 4The side wall of the lifting platform base 14 is fixedly connected with a driving motor 13, and the function of the driving motor 13 is to realize the control of the overall lifting structure. The output end of the driving motor 13 is fixedly connected with a bidirectional threaded rod 12, and the function of the bidirectional threaded rod 12 is to control the different directions of the support block 16. The outer wall of the bidirectional threaded rod 12 is threadedly connected with a supporting block 16, and the function of the supporting block 16 is to realize the supporting effect on the connecting rod 11. The top of the support block 16 is rotatably connected with the connecting rod 11, and the outer wall of the connecting rod 11 is rotatably connected with a rivet 17, and the connecting rod 11 controls the rotation, and the rivet 17 connects the connecting rod 11, and one end of the connecting rod 11 is rotatably connected to a fixed block 10.

The top of the fixed block 10 on one side is fixedly connected to a slider 18, and the bottom of the flat table 1 is fixedly connected to a slide rail 19.

[0026] Working principle: first pull the spring clip 5 to place the scanner body 20 on the placement table 4, then slowly release the spring clip 5. At this time, the scanner body 20 can be stably placed on the placement table 4, and then according to the gravity of the 3D scanner itself, the gravity rotation axis 3 located on the bracket 2 will rotate according to the gravity of the 3D scanner, which can ensure that the 3D scanner is always in a horizontal state to achieve stability.

[0027] Then, when the height needs to be adjusted, the driving motor 13 at the bottom will drive the bidirectional threaded rod 12 to rotate. Since the thread directions of the bidirectional threaded rod 12 are different, the two connected support blocks 16 always maintain bidirectional movement, which enables the connecting rod 11 to control the top slider 18 to move in different directions, thereby realizing the rise and fall of the entire equipment.
