[0031] The use process and working principle of the utility model are as follows: when the gear ring 9 on the flywheel body 1 needs to be replaced, firstly, the limit block 6 is lifted by the lifting and pressing block 7, so that the bottom end of the limit block 6 is disengaged from the limit slot 15 on the limit shaft 14, so as to release the limit fixing state of the limit shaft 14 and the front ring 13, and then the front ring 13 and the limit shaft 14 are removed from the flywheel body 1 to release the limit fixing state of the front end of the gear ring 9, and then the gear ring 9 is removed from the flywheel body 1;

[0032] The new gear ring 9 is put on the outside of the flywheel body 1 and located at the front end of the rear ring 2. At the same time, the positioning groove 10 is engaged with the positioning block 3 to position the gear ring 9 after assembly, and the through hole 2 11 on the gear ring 9 and the through hole 1 4 on the rear ring 2 are connected front to back. Then the front ring 13 is put on the outside of the flywheel body 1 and located at the front end of the gear ring 9. At the same time, the limiting shaft rod 14 on the front ring 13 is passed through the through hole 2 11 and the through hole 1 4 backwards and the rear end of the limiting shaft rod 14 is leaked. When the rear end of the limiting shaft rod 14 is initially in contact with the trapezoidal bottom end of the limiting block 6, under the extrusion force of the rear end of the limiting shaft rod 14, The trapezoidal bottom end of the limit block 6 can be temporarily moved up and retracted into the fixed sleeve 5, and drive the spring 8 to stretch upward. When the front ring 13 and the limit shaft 14 are installed in place, the limit slot 15 on the rear end of the limit shaft 14 coincides with the fixed sleeve 5, and the pressure on the trapezoidal bottom end of the limit block 6 disappears. Under the rebound force of the spring 8, the trapezoidal bottom end of the limit block 6 can bounce down by itself and be stuck in the limit slot 15 to limit and fix the limit shaft 14 and the front ring 13. The front end of the gear ring 9 can be further limited and fixed by the fixedly installed front ring 13, so that the gear ring 9 can be stably installed and used on the flywheel body 1.
