Specifically, the fastener 4 is passed through the insertion hole 13 from the outside of the enclosure assembly 1 to clamp the nut 3 near the supporting end 22, and then force is applied to the active end 21 on the outside of the enclosure assembly 1 to rotate the blade shaft 2, thereby disassembling the nut 3.

[0035] The active end 21 of the blade shaft 2 is connected to the side plate 11 via a bearing, so that the blade shaft 2 can rotate relative to the side plate 11; the support end module 5 supports the support end 22 of the blade shaft 2, so that the blade shaft 2 can maintain high precision and stability under high-speed rotation, thereby improving the service life of the blade shaft 2. The distance from the nut 3 to the support end 22 is smaller than the distance from the nut 3 to the active end 21, and the opening 15 is arranged on the side plate 11 near the support end 22, that is, the opening 15 and the nut 3 are arranged on the same side of the blade, and on the side closer to the support end 22, so that when disassembling, the nut 3 and the blade are taken out from the opening 15 near the support end 22, and when installing, the reverse operation is sufficient.
