[0088] In this embodiment, during transmission, the second transmission shaft 66 rotates with the first rotating member 61. Since the tooth-shaped structure on the outer cylindrical surface of the second transmission shaft 66 meshes with a plurality of second transmission gears 65, the second transmission shaft 66 drives the plurality of second transmission gears 65 to rotate. Since the plurality of second transmission gears 65 mesh with the internal transmission tooth structure 12 in the inner cavity of the housing 1, the second rotating member 64 is driven to rotate in the inner cavity of the housing 1, and the output rotating shaft 31 is driven to rotate through the second transmission member, realizing secondary transmission.

[0089] In this embodiment, three second transmission gears 65 are provided, which can ensure that the second rotating member 64 is uniformly stressed, thus ensuring the stable rotation of the second rotating member 64.
