The threaded rod 201b is moved toward the inside of the motor shaft 104 by rotating the connecting seat 201a. The bottom end of the threaded rod 201b is tapered, so that the movable block 201c can be pushed to move toward the inside of the fan blade 105. At this time, the reset member 202 is deformed by the force, so that the fan blade 105 can be firmly fixed. When the fan blade 105 needs to be removed, the connecting seat 201a is rotated in the opposite direction. At this time, the threaded rod 201b will withdraw from the inside of the motor shaft 104. At the same time, the reset elastic force of the reset member 202 pushes the movable block 201c to move toward the inside of the motor shaft 104, thereby releasing the limit on the fan blade, thereby facilitating the maintenance of the fan blade 105.
[0044] Specifically, two movable blocks 201 c are provided, and one end of the two movable blocks 201 c is inserted into the fan blade 105 .
[0045] By having two movable blocks 201c, the two can simultaneously limit and fix the fan blades 105, thereby making the fan blades 105 more stable when rotating.

[0049] By setting the connecting block 202a and the first spring 202b, when the threaded rod 201b withdraws from the inside of the motor shaft 104, the return elastic force of the first spring 202b can push the connecting block 202a to move, and the connecting block 202a drives the movable block 201c to move, thereby releasing the limit on the fan blade 105.
[0050] Specifically, a side of the connecting block 202 a away from the movable block 201 c is slidably connected to the inner wall of the motor shaft 104 , and one end of the first spring 202 b is fixed to the inner wall of the motor shaft 104 .
[0051] There are two connecting blocks 202a, and both connecting blocks 202a slide in the motor shaft 104. The connecting blocks 202a can remain horizontal when the movable block 201c moves, so that the movable block 201c can be accurately inserted into the hole on the inner wall of the fan blade 105.
[0052] Specifically, the positioning member 203 includes a connecting column 203a, a positioning column 203b and a fixing seat 203c. The connecting column 203a is disposed on both sides of the protective cover 103, the positioning column 203b is located inside the connecting column 203a, and the fixing seat 203c is fixed on both sides of the housing 101.
[0053] The connecting column 203a is rectangular, and the top of the positioning column 203b is located at the top of the connecting column 203a. Through the setting of the positioning column 203b and the fixing seat 203c, the protective cover 103 can be positioned after the protective cover 103 is threadedly connected to the shell 101, so that the protective cover 103 will not loosen, thereby avoiding the protective cover 103 from loosening during long-term use, causing the protective cover 103 to detach from the outside of the shell 101.
[0054] Specifically, two fixing seats 203c are provided, and the two fixing seats 203c and the connecting pillars 203a are vertically fixed to the two sides of the housing 101, and the bottom end of the positioning pillar 203b is inserted into the fixing seat 203c.
[0055] By providing two sets of positioning members 203, the connection between the protective cover 103 and the housing 101 is made more stable, and at the same time, the protective cover 103 is easy to disassemble, which is beneficial to the inspection and maintenance of the interior of the motor.

When the protective cover 103 needs to be removed, the positioning column 203b is first pulled upward so that the bottom end of the positioning column 203b is moved out from the interior of the fixing seat 203c, thereby releasing the limit on the protective cover 103, and then the protective cover 103 can be rotated to remove it from the outer shell 101.
[0058] When in use, when it is necessary to remove the protective cover 103, first pull the positioning column 203b upwards so that the bottom end of the positioning column 203b moves out from the inside of the fixing seat 203c, thereby releasing the limit of the protective cover 103, and then rotate the protective cover 103 to remove it from the housing 101. When the fan blade 105 needs to be repaired, the threaded rod 201b is moved toward the inside of the motor shaft 104 by rotating the connecting seat 201a. The bottom end of the threaded rod 201b is tapered, so that the movable block 201c can be pushed toward the fan blade 105. , and the first spring 202b is deformed by the force, so that the fan blade 105 can be fixed firmly. When the fan blade 105 needs to be removed, the connecting seat 201a is rotated in the opposite direction. At this time, the threaded rod 201b will withdraw from the inside of the motor shaft 104. At the same time, the connecting block 202a is pushed to move by the reset elastic force of the first spring 202b, and the connecting block 202a drives the movable block 201c to move, thereby releasing the limit on the fan blade 105, thereby releasing the limit on the fan blade, thereby facilitating the maintenance of the fan blade 105.
