Two limiting sleeves 9 are fixedly connected to the outer rotor motor 10, and the two fixing blocks 8 can be respectively inserted into the limiting sleeves 9 to prevent the axial rotation of the outer rotor motor 10.

[0019] The two fixing blocks 8 are in contact with the outer rotor motor 10. By using the connecting ring 2 to play a longitudinal limiting role for the outer rotor motor 10, and then fixing by the contact between the fixing blocks 8 and the outer rotor motor 10, so as to play a transverse fixing role for the outer rotor motor 10. When installing the outer rotor motor 10, since no bolts are used for fixing, no external tools are required for installation, so as to quickly and conveniently install the outer rotor motor 10.

[0020] Limiting blocks 3 are fixedly connected to the two connecting edges 4 respectively. By using the limiting blocks 3 to limit the connecting columns 5, the connecting columns 5 are prevented from detaching from the connecting edges 4.

[0021] Second connecting plates 6 are fixedly connected to the two connecting columns 5 respectively. One of the second connecting plates 6 is rotatably connected with a hinge rod 7, a connecting ear 16 is fixedly connected to the hinge rod 7, and the connecting ear 16 is connected to the other second connecting plate 6 through a connecting mechanism. The connecting mechanism includes a column 14, the column 14 penetrates through the connecting ear 16, a connecting disc 12 is fixedly connected to the column 14, a spring 13 is fixedly connected between the connecting disc 12 and the connecting ear 16, the spring 13 is sleeved on the column 14, and a fixing hole 15 is opened on the second connecting plate 6. By inserting the column 14 into the fixing hole 15, the hinge rod 7 plays a connecting role between the two second connecting plates 6, so as to fix the distance between the two connecting columns 5, make the two fixing blocks 8 into one body, prevent the two fixing blocks 8 from moving towards the relatively outer sides, and ensure the fixing effect on the outer rotor motor 10.

[0022] During installation, by putting the outer rotor motor 10 into the connecting ring 2, then moving the connecting columns 5 to make the two fixing blocks 8 contact with the outer rotor motor 10, and then inserting the connecting columns 5 into the fixing holes 15 to fix the distance between the two connecting columns 5, making the two fixing blocks 8 into one body, preventing the two fixing blocks 8 from moving towards the relatively outer sides, and ensuring the fixing effect.

[0023] Embodiment 2: In Embodiment 1, it is difficult to ensure the alignment between the fixing block 8 and the limiting sleeve 9, which is not conducive to the convenience of operation.
