[0013] 1. For the detachable rotor of the axial flow fan, through the provided fixed cylinder, fixed sleeve, fixed bolts and fixed screw ring, when the motor needs to be disassembled, an operator uses a wrench to loosen the two fixed bolts, so that the ends of the fixed bolts are taken out from the inside of the fixed screw ring. At this time, the fan blade is disassembled from the rotating shaft of the motor, and then the fixed sleeve can be taken out from the inside of the fixed cylinder, facilitating the disassembly of the motor.

[0014] 2. For the detachable rotor of the axial flow fan, through the limit insertion rods and limit slots arranged between the fixed cylinder and the fixed sleeve, when the fixed sleeve is inserted into the inside of the fixed cylinder, the limit insertion rods are inserted into the inside of the limit slots, which can increase the installation stability of the fixed sleeve inside the fixed cylinder.
