The uniform arrangement can ensure that at least one actuating piece 12 can drive the driven piece 32 to move as much as possible, and prevent the situation that the actuating piece 12 is difficult to drive the driven piece 32 to rotate around the second rotation center line because the direction of the acting force of all actuating pieces 12, which are abutted against the corresponding driven piece 32, is too close to the second rotation center line 31.

Among the plurality of actuating elements 12, the central angle of two adjacent actuating elements 12 is a first included angle with the first rotation center line 11 as the center.

Furthermore, the actuating member 12 and the driven member 32 are abutted by the corresponding outer surfaces, and the actuating member 12 and the driven member 32 do not need to be connected by the connecting member 403, so that the structure can be simplified to a certain extent and the cost can be reduced.

In one embodiment, referring to fig. 10-12, the sum of the diameter of the actuating member 12 and the diameter of the driven member 32 is greater than or equal to 1.7 times the predetermined distance. In this way, the actuator 12 can be kept in abutment with the follower 32 during rotation, so that the first rotating assembly 1 can better drive the second rotating assembly 3 to rotate, and the actuator 12 is prevented from being out of contact with the follower 32 as much as possible.

For example, referring to fig. 10 to 12, the actuating member 12 and the driven member 32 are cylindrical, the preset distance is D1, the diameter of the actuating member 12 is D2, and the diameter of the driven member 32 is D3, d2+d3 is greater than or equal to 1.7d1.

Through the external engagement of the first gear and the second gear, the motion can be well transferred between the first rotating assembly 1 and the second rotating assembly 3, and the transfer efficiency is improved.

In an embodiment, the sum of the diameter of the bottom circle of the first gear and the diameter of the bottom circle of the second gear is less than or equal to twice the preset distance, and the sum of the diameter of the bottom circle of the first gear and the diameter of the bottom circle of the second gear is greater than or equal to 1.7 times the preset distance.

It will be appreciated that since the follower 32 is fixedly coupled to the driven disk 34 without relative movement therebetween, and without wear between the follower 32 and the driven disk 34 due to friction therebetween, wear of the follower 32 occurs primarily at the location where the follower 32 contacts the actuator 12 without causing wear of the entire outer surface of the follower 32, and thus less wear of the follower 32 and the driven disk 34. Moreover, since the abrasion is small and the driven plate 34 is hardly subjected to the centrifugal load of the connecting member 403 in the related art, the material of the driven plate 34 can be properly reduced to select a material with a lower cost, which is advantageous for reducing the cost, while satisfying the strength requirement of the product.

In this manner, follower 32 does not move relative to driven disk 34 such that driven disk 34 is fixedly coupled to follower 32, which is beneficial for reducing wear of follower 32 and driven disk 34. Furthermore, the follower 32 and the follower disk 34 are integrally formed, so that the number of parts is reduced, and unnecessary disassembly and assembly between the follower disk 34 and the follower 32 are avoided.
