The fine-tuning gap stop block 4 is threadedly connected to the end of the fine-tuning rod support plate 3 close to the fine-tuning base 1. By tightening the fine-tuning gap stop block 4, the bearing 6 and the gap pulling sleeve 5 can be limited to prevent the fine-tuning gap stop block 4 and the bearing 6 from moving.
