Further improvement of the utility model has, and described ratchet device is arranged on the two ends of described driving shaft, and the inner circle of described ratchet device cylindrical and described pull bar is fixed, and described ratchet device inner circle and described driving shaft are fixed.
Further improvement of the utility model also has, and described ratchet device is interior engagement type ratchet mechanism.Ratchet mechanism belongs to prior art, and its structure is no longer described.
Further improvement of the utility model also has, described self-locking device is arranged on the described frame of described driven gear I, driven gear II front, by ratchet, ratchet hinge seat, formed, described ratchet and described ratchet hinge seat are hinged, and be bolted on described frame, with described driven gear I, the corresponding setting of driven gear II.Two ratchet hinge seats can relative motion, by bolt, regulates.
Further improvement of the utility model also has, and described winding roller is arranged on described driven shaft, and the steel wire rope hook is set on described winding roller.
Further improvement of the utility model also has, six sides outside an end of described driving shaft arranges.Complete when stringing, in the time of need to removing the steel wire rope hook, convenient with instrument rigid drive shafts such as pipe wrench.
In specification, do not have the structure of describing to belong to prior art.
The beneficial effect of this programme can be learnt according to the narration to such scheme, a kind of circuit repairing wire stretcher, include frame, driving gear I, driving gear II, driven gear I, driven gear II, driving shaft, driven shaft, winding roller, self-locking device etc., it is characterized in that: also be provided with drag link mechanism on described driving shaft, described drag link mechanism includes pull bar, ratchet device, the described pull bar shape that takes the shape of the letter U, its two ends are connected by described ratchet device with described driving shaft, and described self-locking device adopts the ratchet self-locking.The beneficial effects of the utility model are: ratchet mechanism can only drive the power transmission shaft single direction rotation, even wire shrinks, and pull bar or transfixion, pull bar can not reverse and hurt sb.'s feelings.And simple in structure, easy to use, handling safety.
