[0016] By adopting the above scheme, the provided pin is inserted through the through hole on the lifting plate and into the limiting hole on the turntable, so that the pin limits the position of the lifting plate after it is raised, thereby reducing the probability that the lifting plate automatically drops due to its own gravity or the force exerted on it when the turntable rotates. The pulling component provided at the end of the pin away from the bottom of the limiting hole can facilitate people to insert and remove the pin inserted into the limiting hole.

[0017] Preferably, the pulling component includes a pulling block vertically upwardly arranged at one end of the pin away from the limiting hole and having an end higher than the outer wall of the turntable, and a second limiting component for reducing the probability of the pin escaping from the limiting hole is arranged between the pulling block and the turntable.

[0018] Preferably, the second limiting component comprises a limiting block protruding from the outer wall of the turntable, and a clamping groove is respectively provided on the limiting block and the pulling block, and an elastic rope or a pull rope connecting the two is provided in the two clamping grooves.

[0019] By adopting the above scheme, the connection between the limit block on the outer wall of the turntable and the pulling block on the pin in the limit hole can be achieved through the set elastic rope or pull rope. When the pin is inserted into the limit hole, the two ends of the elastic rope or pull rope can be respectively installed in the limit block and the clamping groove on the pulling block, thereby limiting the position of the pin and reducing the probability of it coming out of the limit hole.

[0020] Preferably, a third limiting component is provided between the latch pin and the limiting hole to further reduce the probability of the latch pin coming out of the limiting hole.

[0021] Preferably, the third limiting component includes magnets that can attract each other and are respectively embedded in the bottom of the limiting hole and on one end of the latch pin close to the bottom of the limiting hole.

[0022] By adopting the above scheme, the probability of the pin inserted into the limiting hole falling out of the limiting hole during the rotation of the turntable can be reduced by the mutual adsorption of the magnets respectively arranged at the bottom of the limiting hole and the end of the pin close to the bottom of the limiting hole.

[0023] The utility model has remarkable technical effects due to the adoption of the above technical scheme: the plug-in block arranged under the fan blade can be inserted into the plug-in slot on the turntable when the fan blade needs to be installed on the turntable, and the position of the lifting plate can be adjusted by the position adjusting component arranged between the lifting plate and the turntable. When the position adjusting component drives the lifting plate to rise, the lifting plate will block the opening of the plug-in slot, thereby reducing the probability of the plug-in block inserted in the plug-in slot being pulled out of the plug-in slot; when the position adjusting component drives the lifting plate to descend, the fan blade can be removed from the turntable, because the disassembly and assembly of the fan blade can be realized only by adjusting the position of the lifting plate by the position adjusting component, so that the fan blade does not need to use other auxiliary tools during the disassembly and assembly process, and the efficiency of the disassembly and assembly of the fan blade is also improved.
