Above technical scheme can be further improved by following measures：

The mounting hole is provided with the neck portion of four circumference in equal parts and is in cross, and the axis body that holds is provided with four Equal rounds Week fastening block part and be in cross.

The discoid location division is provided with four contact seats, and the contact seat mutually staggers with the fastening block part, each described A positioning table is respectively equipped with contact seat, the positioning table is mutually embedding so that the axis body that holds is positioned at described in one with the neck portion On end plate.

The discoid location division is provided with four fabrication holes to stagger with the contact seat.

The axis body that holds is that nylon holds axis body, and the mandrel is steel core shaft.

Each technical measures can select a use above, also can be combined and use, as long as not forming conflict each other.

A kind of cross flow fan, including tubular wine wheel as described above.

The utility model is simple and reasonable, is connected and fixed between rotating shaft and end plate using snap, easy disassembling, both Left end can be mounted in, can also be changed to right-hand member.Rotating shaft is offseted by disc structure and end plate, and positioning precision is high, then coordinates excellent The cross fixture block of choosing, it is not easy to loosen and strict guarantee is concentric.Rotating shaft matches somebody with somebody synthesis type, technique letter using nylon material and steel core shaft Single, cost is low.
