In this structure, since the actuator 12 is provided on the first rotating component 1 and the driven member 32 is provided on the second rotating component 3, during the assembly process, the first rotating component 1 and the second rotating component 3 are rotated to each other for a certain amount of time. The angle causes the actuator 12 and the follower 32 to be staggered by a certain distance. The first rotating component 1 and the second rotating component 3 are brought close to each other and then rotated to each other at a certain angle to make the staggered actuator 12 and the driven member 32 contact each other. connection, so that the power of the first rotating component 1 can be transmitted to the driven component 32 through the actuating component 12, and the driven component 32 drives the second rotating component 3 to rotate.

It can be understood that the actuating member 12 and the driven member 32 may always be in abutting state, but the embodiment of the present application is not limited to the actuating member 12 and the driven member 32 being in a constant abutting state. For example, during the operation of the eccentric rotating device, the actuating member 12 can be in contact with the driven member 32 , and when the eccentric rotating device stops working, the actuating member 12 can be separated from the driven member 32 . For example, the first rotation component 1 drives the actuator 12 to rotate around the first rotation center line 11 at a certain angle so that the actuator 12 contacts the follower 32 .

It should be noted that among the plurality of driven parts 32, with the second rotation center line 31 as the center, the central angle of two adjacent driven parts 32 is the second included angle. The plurality of followers 32 being uniformly arranged along the circumferential direction of the second rotation center line 31 means that any two second included angles are equal and the sum of all second included angles is 360°. For example, the number of the driven members 32 is 7, and the 7 driven members 32 and the second rotation center line 31 form a total of 7 second included angles, and each second included angle is 360°/7, 7 The sum of the second included angles is 360°.
