At the same time, in conjunction with the forward and reverse rotation of the output end of the second motor 5-1-5, the tooth plate 5-1-4 can be used to drive the first sliding cylinder 5-1-2 and the second sliding cylinder 5-1-3 to reciprocate on the outer side of the fixed column 15.

[0056] At the same time, by turning on the third motor 5-1-16, the third motor 5-1-16 can drive the first threaded rod 5-1-17 to rotate, thereby driving the third rotating seat 5-1-14 threadedly connected to the first threaded rod 5-1-17 to move laterally inside the third movable groove.

[0057] By fixing the connection rod 5-1-18 and the sliding connection of the other third rotating seat 5-1-14, the sliding of the third rotating seat 5-1-14 inside the third movable groove can be stabilized and connected, thereby preventing the third rotating seat 5-1-14 from falling out of the third movable groove;

[0058] When the third rotating seat 5-1-14 moves toward the end away from the first rotating seat 5-1-9, it can drive the bottom of the third rotating plate 5-1-13 to move synchronously. At the same time, through the setting of the fixed connection position between the second rotating seat 5-1-12 and the third rotating plate 5-1-13, when the bottom of the third rotating plate 5-1-13 moves, the top of the third rotating plate 5-1-13 will also have the effect of lifting the second rotating seat 5-1-12 upward. Through the rotational connection setting of the first rotating plate 5-1-10 and the first rotating seat 5-1-9 and the second rotating plate 5-1-11, the second rotating plate 5-1-11 can be connected, so that the second rotating plate 5-1-11 fixedly connected to the second rotating seat 5-1-12 can be lifted upward, and the anti-slip pad fixedly connected to the top of the second rotating plate 5-1-11 can be brought into contact and rubbed with the inner wall of the pipeline to be measured;

[0059] The second rotating plate 5-1-11 drives the anti-slip pad to intermittently rub and squeeze the inner wall of the pipeline to be tested, and the toothed plate 5-1-4 drives the first sliding cylinder 5-1-2 and the second sliding cylinder 5-1-3 to move horizontally back and forth outside the fixed column 15, so as to achieve the effect of driving the detection composite component 5 to move on the inner wall of the pipeline to be tested;

[0060] At the same time, by turning on the fourth motor 5-1-11-2, the second threaded rod 5-1-11-3 can be driven to rotate, thereby driving the moving roller 5-1-11-4 to move inside the fourth movable groove, thereby driving the moving roller 5-1-11-4 to pass through the inside of the second rotating plate 5-1-11 and contact the inner wall of the pipeline to be tested. Through the setting of the moving roller 5-1-11-4, the convenience of moving the detection composite component 5 inside the pipeline to be tested can be improved according to actual conditions, thereby facilitating the detection composite component 5 to move inward or outward on the inside of the pipeline to be tested.

[0063] When the detection composite component 5 moves to a turning position inside the pipeline to be tested, the fifth motor 5-2-6 can be controlled and turned on separately to drive the winding drum 5-2-7 to rotate, so that the winding drum 5-2-7 can have a winding and winding effect on the traction line 5-2-8. By changing the length of the traction line 5-2-8, the other end of the traction line 5-2-8 can have a traction effect on the fixed connection seat 5-2-5, so that the first fixed disk 5-2-1 can be pulled. At the same time, through the setting of the connecting hose 5-2-3 and the protective soft cover 5-2-4, it can be adaptively adjusted according to the position and angle between the first fixed disk 5-2-1 and the second fixed disk 5-2-2, so as to improve the convenience of moving the detection composite component 5 inside the pipeline to be tested.

[0064] At the same time, the protective soft cover 5-2-4 can protect the multiple traction lines 5-2-8, thereby preventing the traction lines 5-2-8 from being damaged due to collisions caused by external factors during the movement of the detection composite component 5;

[0065] At the same time, the more the fifth motors 5-2-6 are set, the more accurate the angle adjustment of the first fixed plate 5-2-1 can be.
