Supporting device with high-strength three-tooth thread structure

The invention discloses a supporter with a high-strength three-tooth thread structure, and particularly relates to the technical field of supports.The supporter comprises a mounting cylinder, three-tooth threads are arranged on the inner wall of the mounting cylinder, a threaded cylinder is arranged in the mounting cylinder, the mounting cylinder is in threaded connection with the threaded cylinder through the three-tooth threads, threads are formed in the outer surface of the threaded cylinder, and the threaded cylinder is connected with the mounting cylinder through the three-tooth threads. And the upper surface of the threaded cylinder is fixedly connected with the lower surface of an auxiliary positioning plate. Through the arrangement of the elastic supporting rod, the sealing cylinder, the reinforcing sleeve and the sealing plate, the situation that in the actual use process, due to the fact that pressure borne by a three-tooth thread is too large, the three-tooth thread is seriously abraded is avoided;
