[0021] In the above structure, the clamping plate 15 can be limited by the sliding connection between the clamping plate 15 and the inner wall of the limiting groove 16, thereby preventing the clamping plate 15 from rotating when the limiting groove 16 is rotated.

[0022] In a preferred embodiment, a clamping block 7 is disposed on the inner wall of the rotating frame 18 , threaded holes are formed on the clamping block 7 and the inner wall of the rotating frame 18 , and a threaded rod 8 is threadedly connected to the inner wall of the threaded hole.

[0023] In the above structure, the clamp block 7 is threadedly fixed to the inner side of the rotating frame 18 by the threaded connection between the threaded rod 8 and the inner wall of the threaded hole, and the flange body 17 is clamped and restricted by the L-shaped design of the clamp block 7.

[0024] In a preferred embodiment, circular holes are penetrated through the inner walls of the lap plate 12 and the block 2, and the round rod 11 is slidably connected to the inner wall of the circular hole.

[0025] In the above structure, through the sliding connection between the round rod 11 and the round hole, when the round rod 11 is pulled down, the rotating frame 18 drives the clamping block 7 to disengage from the flange body 17, thereby canceling the clamping restriction on the flange body 17. When the round rod 11 is pulled up, the rotating frame 18 drives the clamping block 7 to fit the two sides of the flange body 17, thereby clamping and restricting the flange body 17.

[0026] In a preferred embodiment, the inner side of the clamping block 7 is arc-shaped, and the inner side of the clamping block 7 is in conformity with the shape of the inner circle of the flange body 17 .

[0031] In the above structure, the threads on the outer edge of the threaded rod 14 are arranged opposite to the lines, so that when the threaded rod 14 is rotated, the two clamping plates 15 can be driven to slide inward at the same time to assist in clamping and limiting the flange body 17 or to separate the two ends of the outer side of the flange body 17.

[0032] Working principle: When the device is needed, firstly, the clamp block 7 can be threadedly fixed on the inner side of the rotating frame 18 by setting the threaded rod 8, and then the inner ring of the flange body 17 can be fitted on the inner arc-shaped outer wall of the clamp block 7. At this time, the round rod 11 can be pulled up so that the round rod 11 drives the connecting frame 9 to rise. At this time, the rotating shaft 3 10 at both ends of the connecting frame 9 drives the connecting rod 6 sleeved on the outer edge of the rotating shaft 3 10 and the outer edge of the rotating shaft 2 5 to rotate, thereby driving the rotating frame 18 to open and close on the outer edge of the rotating shaft 1 4, and through the opening and closing of the rotating frame 18, This drives the clamping block 7 to fit with the outer side of the flange body 17, thereby clamping and limiting the flange body 17. Secondly, by rotating the threaded turning rod 14, the threads arranged on the outer edge of the threaded turning rod 14 with opposite patterns can be used to drive the sliders on the top of the two clamping plates 15 to slide inward on the inner wall of the limiting groove 16 at the same time, thereby driving the two clamping plates 15 to fit close to the outer side of the flange body 17 at the same time, which serves the purpose of auxiliary clamping and limiting the flange body 17, and then performing secondary clamping on the flange body 17, resulting in improved clamping stability of the flange body 17.
