[0033] With the above structure, by setting the detection column 17, the detection column 17 moves to facilitate the detection of damage inside the pipeline, and by setting the fixing plate 15, the fixing plate 15 cooperates with the auxiliary plate 16 to fix the pipeline.

[0034] As a preferred solution of the present invention, the top of the base 1 is rotatably connected to two movable columns 9, and the outer walls of the two movable columns 9 are sleeved with the same movable belt 10. The outer wall of the movable belt 10 is fixedly connected to the left side of the movable plate 8. When the movable plate 8 moves, the movable plate 8 can control the movable belt 10 to rotate in a circle.

[0035] As a preferred solution of the present invention, the rear side of the control panel 2 is slidably connected with a limiting plate 3, and the limiting plate 3 is in active contact with the rear side of the base 1.

[0039] It should be noted that the specific type of electric push rod 7 to be used is selected by relevant technical personnel familiar with this field, and the above electric push rod 7 belongs to the existing technology and is powered by a battery, so this solution will not elaborate on it.

[0040] The working principle of the present utility model is as follows: in actual operation, by placing the pipe adapted to the detection column 17 on the base 1, the control plate 2 is pulled to move at this time, and the control plate 2 can synchronously pull the contact plate 5 and the movable plate 8 to move. When the movable plate 8 moves, the movable plate 8 can synchronously control the movable belt 10 to rotate.

As the driving plate 13 moves, the driving plate 13 can push the push plate 14 to move. When the push plate 14 moves, the push plate 14 can push the fixed plate 15 moves backward. At this time, the fixing plate 15 moves and cooperates with the auxiliary plate 16 to quickly fix the pipeline. At the same time, as the control board 2 moves, the control board 2 drives the contact plate 5 to move to the right side of the detection column 17, and the limiting plate 3 drops and contacts with the rear side of the base 1 to ensure the stability of the movement of the control board 2. At this time, the electric push rod 7 is controlled to work. The electric push rod 7 can push the contact plate 5 to move to the left. When the contact plate 5 moves, the contact plate 5 contacts the detection column 17 and pushes the detection column 17 to extend to the left to the inside of the pipeline. It moves inside the pipeline through the detection column 17. When the movement of the detection column 17 is blocked, it means that the inner wall of the pipeline is uneven due to damage, thereby achieving the effect of automatic non-destructive detection of the inside of the pipeline.
