Specifically, a connecting sleeve 8 is welded to the lower support steels 3 in both the upper and lower triangular frames. The two ends of the reinforcing rod 9 are respectively inserted into the connecting sleeves 8 on the lower support steels 3 in the upper and lower triangular frames, and the two ends of the reinforcing rod 9 are fixed to the connecting sleeves 8 by bolts.

[0020] In practical use, a tripod is formed by welding the upper support steel 1, the diagonal support rod 2, the lower support steel 3, and the support plate 7. The threaded rod 4 is passed through the support plate 7 in the upper and lower tripods, that is, the upper end of the threaded rod 4 passes through the long through hole 71, and the lower end of the threaded rod 4 passes through the through hole 72. At the same time, the connecting sleeve 8 on the lower support steel 3 of the upper and lower tripods is fitted with the reinforcing rod 9, and the connecting sleeve 8 and the reinforcing rod 9 are fixed together with bolts. The upper and lower fastening nuts 5 are tightened, and the fastening nuts 5 and the support ring 6 clamp the support plate 7 to achieve the fixation of the threaded rod 4 to the two tripods.
