[0031] Example: Figure 1-Figure 4 As shown, the working principle of a line-releasing mechanism for a pipeline endoscope of the utility model is as follows: when using the utility model, firstly, the support column 5 is raised by controlling the handrail 10, and then the device is pushed to the working position, and the support column 5 is lowered. The universal wheel 6 can realize the rapid transportation of the device. The support column 5 is used to ensure that the device will not move at will. When releasing the line, the cable is first passed through the fixed ring 16, and then the driving motor 8 is driven to rotate in the reverse direction at a low speed, which plays a certain auxiliary role and is convenient for manual pulling of the cable.
