The reinforcing mechanism comprises a mounting disc 501 fixedly connected to the lower end of the threaded cylinder 402. The mounting disc 501 is uniformly provided with a plurality of support plates 502 in the circumferential direction. The support plates 502 are hingedly connected to the lower end of the mounting disc 501. A torsional spring is arranged in the hinge shaft of the support plate 502. The plurality of support plates 502 are in a V shape with the pointed ends downward. The V-shaped support plates 502 are in communication with the threaded cylinder 402. A protrusion 503 is fixedly connected to the inner wall of the support plate 502. A threaded rod 504 is threadedly connected to the upper end of the threaded cylinder 402. A pressing block 505 is fixedly connected to the lower end of the threaded rod 504.
