The spring (400) applies an elastic force to the rotating ring (300) to rotate it from the first position to the second position.

2. The fan blade mounting structure according to claim 1, characterized by: The wheel body (100) is provided with a limiting wall (120) inside. The limiting wall (120) is arranged around the central axis of the wheel body (100). A circular guide groove (130) is defined between the limiting wall (120) and the outer peripheral wall of the wheel body (100). The rotating ring (300) is installed in the guide groove (130) and rotates coaxially with respect to the guide groove (130).

3. The fan blade mounting structure according to claim 2, characterized by: A connecting post (140) is provided in the guide groove (130), and a through groove (311) extending around the central axis of the rotating ring (300) is provided on the mounting groove (310). The connecting post (140) passes through the through groove (311) and can slide relative to the through groove (311) around the axial direction of the rotating ring (300). One end of the spring (400) abuts against the connecting post (140), and the other end of the spring (400) abuts against the mounting groove (310).

4. The fan blade mounting structure according to claim 3, characterized by: The wheel body (100) includes a front shell (150) and a rear shell (160). The connecting post (140) is disposed on the front shell (150) and extends parallel to the axial direction of the wheel body (100). The front shell (150) and the rear shell (160) are connected to each other along the axial direction of the wheel body (100) by the connecting post (140) and a screw.

5. The fan blade mounting structure according to claim 3 or 4, characterized by: The end of the mounting groove (310) is provided with a protrusion (312), the protrusion (312) protrudes toward the connecting post (140), and one end of the spring (400) is sleeved on the protrusion (312) and abuts against the mounting groove (310).

6. The fan blade mounting structure according to claim 1, characterized by: The rotating ring (300) has multiple interfaces (320) circumferentially arranged, and each interface (320) is positioned opposite to each mounting port (110). The blade (200) is provided with a limiting part (210). When the rotating ring (300) is in the first position, the limiting part (210) can pass through the mounting port (110) and the interface (320) radially into the wheel body (100). When the limiting part (210) is inserted into the wheel body (100) and the rotating ring (300) rotates to the second position, the limiting part (210) can abut against the inner wall of the rotating ring (300).

7. The fan blade mounting structure according to claim 1 or 6, characterized by: The rotating ring (300) can also rotate relative to the wheel body (100) to a third position that locks the blade (200) on the wheel body (100), the first position, the second position and the third position being distributed sequentially along the circumference of the rotating ring (300).

8. The fan blade mounting structure according to claim 7, characterized by: The wheel body (100) is provided with a limiting wall (120) inside. The limiting wall (120) is provided with a first locking recess (121) and a second locking recess (122). The first locking recess (121) and the second locking recess (122) are distributed sequentially around the central axis of the wheel body (100). The rotating ring (300) is provided with an elastic locking protrusion (330). When the rotating ring (300) rotates between the first position and the second position, the elastic locking protrusion (330) slides in the first locking recess (121). When the rotating ring (300) rotates to the third position, the elastic locking protrusion (330) slides out of the first locking recess (121) and slides into and locks onto the second locking recess (122).
