Referring to Figures 2 and 3, the fixing table 10 includes an upper portion 11 and a lower portion 12 which are disposed in parallel, and the upper portion 11 and the lower portion 12 are fixedly coupled together by a support rod 13. In the present embodiment, the upper portion 11 and the lower portion 12 are both circular plates, and the radius of the upper portion 11 is smaller than the radius of the lower portion 12, and the lower portion 12 is formed with a boss 120 away from the upper portion 11. The upper portion 11 is provided with two fixed arms 111, and the driving source 20 is fixed between the two fixed arms 111 (refer to FIG. 1). The fixing table 10 further includes a through hole 101 penetrating through the upper portion 11 and a through hole 14 extending through the lower portion 12. The through hole 101 and the through hole 14 are coaxial, and the inner diameter of the through hole 14 is larger than the inner diameter of the through hole 101. An annular groove 122 is formed inwardly on the inner wall of the through hole 14, and the inner diameter of the annular groove 122 is larger than the inner diameter of the through hole 14.

The drive source 20 includes an output shaft 21. The first transmission member 30 is sleeved on the output shaft 21, and the outer circumference thereof is provided with meshing teeth. The first transmission member 30 is rotated by the driving source 20.

The second transmission member 40 is elongated and includes a rack portion 41 and a threaded shaft portion 42. The second transmission member 40 is located in the coaxial through holes 101, 14. The rack portion 41 of the second transmission member 40 passes through the through hole 101, and the rack portion 41 is engaged with the first transmission member 30, thereby, when the first transmission member When the driving source 20 rotates, the second transmission member 40 correspondingly moves in the axial direction of the through hole 14.

The third transmission member 50 includes a rotating portion 51. The rotating portion 51 has a gourd shape and includes an upper flange 52 and a lower flange 53 opposite to the upper flange 52. The intersection of the upper flange 52 and the lower flange 53 forms a neck portion 54, an upper flange 52 and The diameter of the lower flange 53 is larger than the diameter of the neck portion 54 and smaller than the inner diameter of the through hole 14. Further, the rotating portion 51 is provided with a threaded hole 55 penetrating the upper flange 52 and the lower flange 53, wherein the threaded hole 55 is for engaging with the threaded shaft portion 42 of the second transmission member 40.

The third transmission member 50 further includes a support post 56. In the present embodiment, the number of the support posts 56 is four, and one end of the support post 56 and the lower flange 53 are fixedly coupled. The other end of the support post 56 is used for connecting and supporting the electronic device 200, and the fixing manner of the electronic device 200 may be a screw connection or other fixing manner.

The rotating device 100 further includes a snap ring 60. The snap ring 60 is a resilient member having a notch. In the natural state, the outer diameter of the snap ring 60 is larger than the inner diameter of the through hole 14 and smaller than or equal to the inner portion of the annular groove 122. The diameter, when pressed, the outer diameter of the snap ring 60 becomes smaller than the inner diameter of the through hole 14.

The assembly process of the rotating device 100 is as follows. First, the snap ring 60 is sleeved on the neck portion 54 and the snap ring 60 is pressed inwardly so that the outer diameter thereof is smaller than the inner diameter of the through hole 14, and then the snap ring 60 is sleeved. The third transmission member 50 is inserted into the through hole 14 until the snap ring 60 is inserted into the annular groove 122. At this time, the snap ring 60 is elastically restored, and the outer diameter of the snap ring 60 is enlarged and engaged with the annular groove 122, thereby making the third The transmission member 50 is rotatably fixed to the fixed table 10.

The operation of the rotating device 100 is as follows. When the driving source 20 drives the first transmission member 30 to rotate, the first transmission member 30 with the meshing teeth drives the rack portion 41 of the second transmission member 40, so that the second transmission member 40 is caused. Movement along the axial direction of the through hole 14. Since the threaded shaft portion 42 of the second transmission member 40 and the threaded hole 55 of the third transmission member 50 are engaged and the third transmission member 50 is mounted at the annular groove 122 of the fixed table 10, when the second transmission member 40 is along the through hole When the axial movement of 14 is performed, correspondingly, the third transmission member 50 and the electronic device 200 fixed to the third transmission member 50 rotate relative to the fixed table 10, thereby rotating the electronic device 200 to a proper angle. Since the rotation accuracy of the driving source 20 is high, high-precision rotation of the electronic device 200 can be achieved.

Embodiments of the invention are not limited thereto, for example, in other embodiments, the rotating portion 51 of the third transmission member 50 may not include a lower flange. The outer diameter of the rotating portion 51 is set to be larger than the inner diameter of the through hole 14 and equal to or smaller than the inner diameter of the annular groove 122. When installed, first, the third transmission member 50 is placed in a nitrogen gas to be cooled and contracted until the outer diameter of the rotating portion 51 is smaller than the inner diameter of the through hole 14, and the rotating portion 51 of the third transmission member 50 is inserted into the fixed table 10. In the annular groove 122 in the through hole 14, when the third transmission member 50 is restored to its original shape, the rotating portion 51 just fits the size of the annular groove 122, thus realizing the assembly of the third transmission member 50 and the fixed table.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
