[0023] Working principle:

[0024] When in use, the power cable is wound on the winding drum 4. During the winding process, one hand can pull the pull rod 11 to drive the slider 10 to be pulled in the slide groove 8 toward the outside of the rotating wheel 3, so that the distance between the pressure plate 12 and the winding drum 4 is increased, and the other hand passes the power cable through the gap between the winding drum 4 and the pressure plate 12 for winding. After the winding is completed, the pull rod 11 can be released by the hand. At this time, the slider 10 is reset by the spring tension of the spring 9, thereby pulling the pressure plate 12 closer to the winding drum 4, and the corrugated area 13 on the end face of the pressure plate 12 presses against the outer surface of the power cable wound on the outer surface of the winding drum 4, which plays the role of tightening the wound power cable, reducing the problem of cable scattering due to inertia when pulling the winding drum 4 to rotate during cable laying.
