The output shaft is connected, and a bearing seat 10 is provided in the middle of the lower bottom wall of the rotating frame 4. The bearing seat 10 supports and limits the threaded rod 7. The threaded rod 7 is a bidirectional threaded rod 7. The two ends of the bidirectional threaded rod 7 are symmetrically threaded with threaded seats 9. The upper end of the threaded seat 9 is in sliding contact with the bottom wall of the rotating frame 4. A support sleeve 11 is provided at the lower end of the threaded seat 9.
