Adopt between sealing ring 9 and the seal groove 10 to connect again after fixed between first casing 1 and the second casing 2, guaranteed the leakproofness of first casing 1 and second casing 2 hookup location, the drawback that structures such as cotton filter layer used and can not pass through the high-speed water impact has been solved in the use of elastic metal casing 44.

The working principle is as follows: in the invention, the outer rotating ring 34 and the inner rotating ring 35 are kept to be repellent and far away through the first magnetic block 37 and the second magnetic block 38, so that the outer rotating ring 34 can always have the supporting force towards the inner wall of the bearing matching sleeve 24, the inner rotating ring 35 has the supporting force towards the outer ring of the second power shaft 22, and the phenomenon that the interference fit structure among the bearing matching sleeve 24, the outer rotating ring 34 and the inner rotating ring 35 is loosened is avoided.

Further, the bearings 23 are provided with two sets, so that the connecting area between the second power shaft 22, the bearing matching sleeve 24 and the bearings 23 can be increased, the stability between the structures can be increased, the bearing 23 is further prevented from slipping, and when the bearing is used specifically, a plurality of sets of bearings 23 can be arranged according to actual requirements.

In order to avoid the phenomenon that the bearing matching sleeve 24 is loosened or slipped off, the bearing matching sleeve 24 is provided with the reinforcing connecting plate 4, the fixing plate 5 at the end part of the reinforcing connecting plate 4 is fixed on the second shell 2 through a screw, the connecting structure is stable and double-fixed, when the second power shaft 22 rotates at a high speed, the temperature generated at the position of the bearing 23 at the outer ring of the second power shaft 22 is higher, the bearing matching sleeve 24 is deformed to a certain degree at higher temperature, and the screw at the connecting part between the bearing matching sleeve 24 and the second shell 2 is easy to loosen and slip off, however, the bearing matching sleeve 24 adopts a double-fixing mode in the invention, the influence of the heat quantity on the position of the fixing plate 5 at the end part of the reinforcing connecting plate 4 is small, and the phenomenon that the screw connected between the bearing matching sleeve 24 and the second shell 2 is loosened or slipped off is avoided.
