The large gear 22 is connected with the tape wheel shaft 24 for installing the tape roll 25, the tape tensioner for tensioning the tape, and the tape cutting knife for cutting the tape. The small gear is the driving gear, and the large gear is the driven gear. During the rotation of the large gear, the insulating tape is pulled out from the tape roll and wound on the repairing position of the overhead power distribution line. During this process, the tape tensioner always tensions the insulating tape, and finally The tape is cut off by the tape cutting knife, and the whole repair process is completed.
