However, this manual adjustment method has some disadvantages: due to the difficulty of maintaining absolute uniformity in manual operation, or due to improper operation skills, it is easy to cause the threading device to deviate or tilt during adjustment. Although these deviations or tilts seem insignificant at the initial adjustment, in actual threading operation, these small position changes may be significantly magnified, and thus a series of problems may be caused. For example, the cable may not pass through the device smoothly, or even if it passes through, it may be damaged on the surface due to the incorrect path, and even affect the performance of the entire electrical system.
