This invention relates to the field of planetary gear technology, specifically to a structure and method for preventing planetary gear shaft detachment. By creating coaxial first and second holes on the planet carrier and planetary gear shaft respectively, an elastic cylindrical pin is inserted into both holes, utilizing its elasticity to provide radial force for radial fastening.
