[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 4The large ceiling fan with good stability comprises a ceiling fan motor 1 and a plurality of fan blades 2. The ceiling fan motor 1 comprises a motor stator 11 and a motor rotor 12 arranged on the outside thereof. An upper positioning plate 3 and a lower positioning plate 4 are respectively arranged on the upper and lower sides of the motor rotor 12. The fan blades 2 are distributed on the upper positioning plate 3 or the lower positioning plate 4 along the circumferential direction. A first locking mechanism is arranged between the fan blades 2 and the upper positioning plate 3 or the lower positioning plate 4. The fan blades 2 are connected and fixed to the upper positioning plate 3 or the lower positioning plate 4 through the first locking mechanism. The first locking mechanism can make the force on the motor rotor 12 along the circumferential direction more uniform.

[0023] A second locking mechanism is provided between the upper positioning plate 3 and the lower positioning plate 4 , and the upper positioning plate 3 and the lower positioning plate 4 are connected and fixed by the second locking mechanism. The second locking mechanism can make the force on the upper and lower sides of the motor rotor 12 more uniform.

[0024] By providing the upper positioning plate 3 and the lower positioning plate 4, the fan blades 2 do not need to be directly mounted and connected to the motor rotor 12, and the overall force of the motor rotor 12 is more uniform, thereby improving the operating stability of the motor rotor 12.

[0025] Furthermore, the vertical projection area of ​​the lower positioning plate 4 is larger than the vertical projection area of ​​the upper positioning plate 3, and the fan blade 2 is connected and fixed to the lower positioning plate 4 by a first locking mechanism, so that the fan blade 2 is more stable when installed on the lower positioning plate 4, and the lower positioning plate 4 will not affect the downward flow of the airflow generated by the fan blade 2.

[0026] Furthermore, the first locking mechanism includes a plurality of first screws 51, and screw holes corresponding to the first screws 51 are respectively provided on the fan blades 2 and the lower positioning plate 4.
