[0020] A first connecting shaft 5 is installed at one end of the shaft core rod 3, and a second connecting shaft 6 is installed at the other end of the shaft core rod 3. Both ends of the shaft core rod 3 are provided with inner mounting grooves 4 that mate with the first connecting shaft 5 and the second connecting shaft 6. Both the first connecting shaft 5 and the second connecting shaft 6 are provided with outer mounting parts. The second positioning block 8 is fixedly connected to one side of the support sleeve 2 at equal intervals. The side mounting grooves 13 are symmetrically opened on the outside of the rotor 1 and mate with the second positioning block 8.

[0021] It should be noted that, in this embodiment, when the support sleeves 2 are installed on both sides of the rotor 1, the support sleeves 2 are fitted onto the outer side of the shaft core rod 3. Each of the second positioning blocks 8 on one side of the support sleeve 2 is positioned between the support sleeve 2 and the side mounting groove 13, thus positioning and installing the support sleeve 2 on the outer side of the rotor 1. Multiple bolts are used to fix the support sleeve 2 and the rotor 1 together. The support sleeve 2 improves the stability between the shaft core rod 3 and the rotor 1. The first connecting shaft 5 and the second connecting shaft 6 are installed at both ends of the shaft core rod 3. The first connecting shaft 5 and the second connecting shaft 6 cooperate with the inner mounting grooves 4 at both ends of the shaft core rod 3. The outer side positioning groove 10 cooperates with each inner positioning block 11 inside the inner mounting groove 4 for positioning, thus limiting the installation of the first connecting shaft 5 and the second connecting shaft 6 at both ends of the shaft core rod 3. Simultaneously, the first positioning block 7 enters the inner positioning groove 12 within the inner mounting groove 4. Internally, the installation positions of connecting shaft 5 (number one), connecting shaft 6 (number two), and shaft core rod 3 are positioned and fixed. The outer mounting base 9 is then secured to the shaft core rod 3 using multiple bolts.

[0027] In one embodiment, such as Figure 2 to Figure 5 As shown, multiple side positioning grooves 10 are equally spaced on the outer sides of both the first connecting shaft 5 and the second connecting shaft 6.

[0028] It should be noted that in this embodiment, multiple side positioning grooves 10 for positioning are equidistantly opened on the outer side of the first connecting shaft 5.

[0029] In one embodiment, such as Figure 2 to Figure 5 As shown, multiple inner positioning blocks 11 that cooperate with the side positioning slot 10 are fixedly connected at equal intervals on the inner side of the inner mounting slot 4.

[0030] It should be noted that in this embodiment, the inner positioning block 11 inside the inner mounting groove 4 is positioned with the side positioning groove 10, and the first connecting shaft 5 and the second connecting shaft 6 are positioned and installed inside the inner mounting groove 4, which improves the stability of the installation of the first connecting shaft 5 and the second connecting shaft 6.
