The first fan (11) includes a first frame body (111) with a wind incoming side (1111) and a connection side (1113) at two sides, a first dynamic blade impeller (13) and a first shaft seat (15). The first dynamic blade impeller (13) is pivotally disposed on the first shaft seat (15) and has first dynamic blades (131). The second fan (21) includes a second frame body (211), a second dynamic blade impeller (23) and a second shaft seat (25). Two sides of the second frame body (211) are formed with a wind outgoing side (2111) and a mating side (2113) mated with the connection side in communication therewith. The second dynamic blade impeller (23) is pivotally disposed on the second shaft seat (25) and has second dynamic blades (231). At least one connected section (2311) of the second dynamic blade (231) is connected with at least one connection section (1311) of the first dynamic blade (131) to form integrally a driving blade (31).
