Then, the position of the brake handle B09 is adjusted, after the brake handle B09 is adjusted according to the preference of an maintainer, the manual carrying handle B13 is shifted, meanwhile, the handle locking clamp B14 rotates according to a thread form and gradually closes to the hoop B11, meanwhile, the lock tongue B16 is pushed to gradually insert into a lock hole on the side face of the hoop B11, the number of the lock tongue B16 and the lock hole can be set according to the situation, the more and the safer the more, the lock tongue B16 reaches the locking position and locks the hoop B11, and then the locking clamp B14 is fastened through a fastening bolt on the outer side of the locking clamp B14, so that the sliding buckle is prevented. The safety rope 4 at the rear side of the brake handle B09 passes through the guide ring C04 and is buckled on the worn safety protection rope. At this time, the connection of the general connection part is completed, then an maintainer holds the brake handle B09 by hand, pulls the stay wire A15 and simultaneously lifts the L-shaped supporting rod A06, so that the transmission line is clamped between the rolling wheel A11 and the lower wire clamping support A07, but the clamping cannot be too tight, as long as the transmission line is ensured not to deviate from between the rolling wheel A11 and the lower wire clamping support A07, then the positions of the hanging ring 5 at the tail end of the safety rope 4 and the safety protection rope are adjusted, and the best position of the maintainer is achieved. The safety protection rope is provided with a plurality of hooks for hanging the hanging ring 5, which is used for the fat and thin degree of the maintainer.
