Four sets of rubber blocks 8 are arranged above the base plate 1. The inner support mechanism 4 is arranged on the mounting shells 3. The inner support mechanism 4 is used to drive the multiple sets of rubber plates 5 to support the inner wall of metal corrugated pipes of different sizes.

[0023] The internal support mechanism 4 includes a motor 401, a rotating plate 402, a sliding rod 403, and a connecting rod 404. There are two sets of internal support mechanisms 4, which are symmetrically arranged on adjacent sides of the mounting housing 3. A set of motors 401 is fixedly installed on each non-adjacent side of the two sets of mounting housing 3. The output shaft of the motor 401 extends into the interior of the mounting housing 3 and is fixedly installed on the rotating plate 402. The rotating plate 402 has multiple sets of arc-shaped openings, and a set of sliding rods 403 is slidably installed in each set of arc-shaped openings. A set of connecting rods 404 is hinged to the outer wall of each set of sliding rods 403. The internal support mechanism 4 can drive the rubber plate 5 to support the inner wall of metal corrugated pipes of different sizes, avoiding the thinness of the inner wall of the metal pipe and causing deformation during processing, thus improving the processing quality of the metal corrugated pipe.

[0024] One end of each of the multiple sets of connecting rods 404 is fixedly connected to a set of rubber plates 5, and both sets of rotating plates 402 are rotatably installed inside a set of mounting housings 3.

[0025] Two sets of fixing plates 6 are fixedly installed on the non-adjacent sides of the two sets of mounting housings 3. A set of threaded rods 7 are threadedly connected to the top of each of the four sets of fixing plates 6. One end of each of the four sets of threaded rods 7 extends into the interior of a set of fixing plates 6 and is rotatably installed with a set of rubber blocks 8. A set of handles 9 is fixedly installed at the other end of each of the four sets of threaded rods 7.

One end of each set of connecting plates 2 is fixedly connected to a set of mounting housings 3.

[0028] Working principle: When work is required, one end of the corrugated pipe is inserted into a fixed space composed of multiple sets of rubber plates 5. A set of motors 401 is started, and the output shaft of the set of motors 401 drives the rotating plate 402 to rotate. This causes multiple sets of sliding rods 403 to drive the connecting rods 404 to contact the inner wall of the pipe and support it. By rotating the two sets of threaded rods 7 through the two sets of handles 9, the two sets of rubber blocks 8 can be driven to fix the outer wall of the pipe. By rotating the threaded rod 10 through the handle 11, the threaded rod 10 can be driven to rotate, which in turn drives a set of connecting plates 2 to slide, inserting the other end of the pipe into a fixed space composed of another set of multiple sets of rubber plates 5. The operation is repeated to fix the other end of the pipe.
