Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be embodied in many other forms without departing from the spirit or essential characteristics thereof, and it should be understood that the invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1-2, a boss-deforming planetary gear trip mechanism 100 includes a planet carrier, a planet gear 101, and a sun gear 102. The planet carrier comprises a flexible inner ring 103 and an outer ring 104 which are coaxially arranged, and the flexible inner ring 103 can generate certain deformation in the radial direction. The inner ring 103 and the outer ring 104 may be made of the same material or different materials, and preferably, the entire planet carrier is made of a plastic material.

The inner wall of the inner ring 103 is provided with a plurality of lugs 105, and ribs 106 are connected between the outer ring 104 and the inner ring 103.
