At least two metal conductive rings 23 which are arranged at an insulating interval from top to bottom and are respectively in a circular ring shape sleeve the periphery of the conductive ring mounting sleeve 22. The decorative light strings 12 are electrically connected with the metal conductive rings 23 through wires.

[0030] Further, as shown in FIG. 2 to FIG. 4, the supporting base 3 is respectively provided with metal contacts 24 corresponding to the metal conductive rings 23. Each metal contact 24 is in contact with the corresponding metal conductive ring 23 and is electrically conductive.

[0031] It should be noted that, for the rotatable artificial tree according to the first embodiment, the metal contacts are electrically connected with an external power supply through wires, and wires connected to the metal conductive rings 23 can be electrically connected with the decorative light strings 12 of the artificial tree body 1 through plugging connectors. In working hours, the driving motor 4 starts and drives the rotating shaft core 21 to rotate, the rotating shaft core 21 drives the trunk 11 of the artificial tree body 1 to rotate, and then the whole artificial tree body 1 rotate. In this process, the conductive ring mounting sleeve 22 and each metal conductive ring 23 mounted on the conductive ring mounting sleeve 22 respectively rotate synchronously with the rotating shaft core 21, namely each metal conductive ring 23 is in sliding contact with the corresponding metal contact 24 and is electrically conductive.

[0032] It should be emphasized that the rotatable electric assembly 2 in the first embodiment includes a rotating shaft core 21, a conductive ring mounting sleeve 22, a metal conductive ring 23 and a metal contact 24, so that the overall structure is simple. During assembling, the rotating shaft core 21 is mounted on the power output shaft of the driving motor 4, and the conductive ring provided with the metal conductive ring 23 sleeves the rotating shaft core 21 to ensure that each metal conductive ring 23 is in contact with the corresponding metal contact 24, so that the assembly is convenient and quick.

[0033] In these circumstances, by means of the structural design, the rotatable artificial tree in the first embodiment has the advantages of being novel in design, simple in structure and convenient to assemble.

[0034] In the second embodiment, as shown in FIG. 3, the difference between the second embodiment and the first embodiment lies in that the supporting base 3 is respectively provided with contact mounting parts 31 corresponding to the metal contacts 24. Each contact mounting part 31 is respectively provided with a contact clamping groove 32. Each metal contact 24 is respectively clamped and fixed in the corresponding contact clamping groove 32.

[0035] The mounting structure of the metal contact 24 has the advantage of being convenient and quick to mount.

[0036] In the third embodiment, as shown in FIG. 4, the difference between the third embodiment and the first embodiment lies in that the metal contact 24 is C-shaped, and includes a contact base 241 and contact extension parts 242 symmetrically arranged at both ends of the contact base 241. Each contact extension part 242 is respectively provided with an elastic contact part 243.

[0038] Each metal contact 24 is respectively in contact with the corresponding metal conductive ring 23 through the corresponding elastic contact part 243 and is electrically conductive. The structural design can ensure the stability and reliability of the electric connection between the metal contact 24 and the metal conductive ring 23.

[0039] In the fourth embodiment, as shown in FIG. 2, the difference between the fourth embodiment and the first embodiment lies in that in order to facilitate to mount the trunk 11 of the artificial tree body 1, the fourth embodiment is designed by using the following structure. Specifically, an upper end of the supporting base 3 is rotatably provided with a linkage sleeve 5. An upward insertion hole 51 is formed in a core of the linkage sleeve 5. A lower end of the trunk 11 of the artificial tree body 1 is inserted into the insertion hole 51 of the linkage sleeve 5. A lower end of the linkage sleeve 5 is in sleeve connection with an upper end of the rotating shaft core 21 in a non-rotating manner.

[0040] In working hours, the driving motor 4 drives the rotating shaft core 21 to rotate, the rotating shaft core 21 drives the trunk 11 to rotate synchronously through the linkage sleeve 5, and then the whole artificial tree body 1 rotates.

[0041] In the fifth embodiment, as shown in FIG. 2, the difference between the fifth embodiment and the fourth embodiment lies in that a circle of bottom balls 61 are arranged between a lower surface of the linkage sleeve 5 and the supporting base 3, and the lower surface of the linkage sleeve 5 is in rolling contact with the bottom balls 61.

That is, through the design of the bottom ball 61 and the side ball 62, the fifth embodiment can effectively improve the smoothness of the rotation of the linkage sleeve 5.
