[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the utility model provides a rotating module, including a lower circular ring 1 and an upper circular ring 2. The top surface of the lower circular ring 1 forms a concentrically arranged annular groove 11, and the upper circular ring 2 is embedded in the annular groove 11 to form a coaxial rotation fit with the lower circular ring 1; the lower circular ring 1 includes a first half ring 101 and a second half ring 102 that are detachably spliced into a circular ring, and the upper circular ring 2 includes a third half ring 201 and a fourth half ring 202 that are detachably spliced into a circular ring.
[0025] In the above technical solution, the lower ring 1 is placed flat on a table, the upper ring 2 is embedded in the annular groove 11 to form a coaxial rotation fit with the lower ring 1, and the top surface of the upper ring 2 is used to support the rotating object that is desired to rotate. The rotating object and the upper ring 2 are arranged in the center, forming a central rotation mechanism.
[0026] In the above technical solution, since the lower ring 1 and the upper ring 2 adopt a detachable combined structure, and the lower ring 1 and the upper ring 2 can be split into semi-rings respectively, they are easy to store, occupy a smaller space, and have better portability.
[0027] As an improvement on one aspect, the first half ring 101 has first plug connectors 1011 at both ends, the second half ring 102 has first sockets 1021 corresponding to the first plug connector 1011 at both ends, and the first plug connector 1011 is detachably connected to the corresponding first socket 1021; the third half ring 201 has second plug connectors 2011 at both ends, the fourth half ring 202 has second sockets 2021 corresponding to the second plug connector 2011 at both ends, and the second plug connector 2011 is detachably connected to the corresponding second socket 2021.
[0028] Furthermore, the bottom surface of the second half ring 102 has a screw 103 that penetrates upward into the first socket 1021 and is connected to the first plug connector 1011 in the first plug connector 1011. Obviously, when the screw 103 is tightened, the first plug connector 1011 will be locked in the first socket 1021, so that the first half ring 101 and the second half ring 102 remain connected, and the lower ring 1 will obtain a stable assembly posture. When the screw 103 is removed, the locking of the first plug connector 1011 in the first socket 1021 is released.
[0029] Furthermore, the plug end of the second plug connector 2011 has a pair of elastic arms 2012 opened into a U shape, and the elastic arms 2012 have oblique wedge-shaped protrusions 2013 formed at the ends on the opposite sides thereof, and the inner wall of the second socket 2021 has grooves 2022 corresponding to the protrusions 2013 one by one; when the second plug connector 2011 is inserted into the second socket 2021, the spacing between the elastic arms 2012 is constrained by the second socket 2021 and becomes smaller, and the protrusions 2013 are embedded in the corresponding grooves 2022 under the elastic stress of the elastic arms 2012. Generally, the elastic stress of the elastic arms 2012 can be generated by the characteristics of the injection molding material. When the second plug connector 2011 is pulled out of the second socket 2021, the elastic stress of the elastic arms 2012 needs to be overcome, and this obviously enables the lower ring 1 to obtain a relatively stable assembly posture. At the same time, since the protrusion 2013 is fitted in the groove 2022 in an oblique wedge-shaped structure, the second plug connector 2011 is not locked in the second socket 2021, but the plugging and unplugging operations can be achieved by overcoming the elastic stress of the elastic arm 2012.
[0030] Furthermore, the plug end of the second plug connector 2011 forms an oblique wedge-shaped block 2014 on the bottom surface, and the inner wall of the second socket 2021 has a slot 2023 that matches the block 2014. When the second plug connector 2011 is inserted into the second socket 2021, the block 2014 is embedded in the slot 2023 under the elastic stress of the second socket 2021. Generally, the elastic stress of the second socket 2021 can be generated by the characteristics of the injection molding material.
[0031] At least two positioning posts 203 extend out from the end faces at both ends of the third half ring 201, and positioning holes 204 corresponding to the positioning posts 203 are respectively arranged on the end faces at both ends of the fourth half ring 202; when the second plug connector 2011 is connected to the corresponding second socket 2021, the positioning posts 203 are coaxially inserted into the corresponding positioning holes 204, which will help users to achieve positioning more easily when assembling the third half ring 201 and the fourth half ring 202.
[0032] As another improvement, the bottom surfaces of the third half ring 201 and the fourth half ring 202 are respectively provided with a plurality of rotating members 3 distributed at intervals in the circumferential direction of the upper circular ring 2 , and the upper circular ring 2 forms a rotational fit with the lower circular ring 1 via the rotating members 3 .
[0033] Furthermore, the rotating member 3 is a roller shaft axially arranged along the radial direction of the upper ring 2, and central shafts 31 are arranged along the axis at both ends of the rotating member 3, and the bottom surfaces of the third half ring 201 and the fourth half ring 202 have U-shaped grooves 200 for the central shafts 31 to correspond one to one, and the central shafts 31 are embedded in the corresponding U-shaped grooves 200. Since the rotating member 3 is a roller shaft axially arranged along the radial direction of the upper ring 2, the upper ring 2 can obtain better concentricity when rotating relative to the lower ring 1.
[0034] Furthermore, an annular guide rail 100 located at the bottom surface of the annular groove 11 is respectively provided on the first half ring 101 and the second half ring 102, and the cylindrical surface of the roller is supported on the annular guide rail 100, which helps to reduce friction and noise.
[0035] Furthermore, the annular guide rail 100 has two concentrically spaced apart rails.

Without departing from the spirit or basic characteristics of the present invention, the equivalent meanings and all changes in the protection scope made by those skilled in the art based on the requirements of the present invention should be included in the present invention.
