10. patch insert method according to claim 9, it is characterized in that: the described 2nd) controlling the clipping chuck of flexible cable tensioning in step, to be in clamped condition be shrink by controlling the piston rod of clamping cylinder, drive and pull bar, thrust bearing and chuck slide block move, when chuck slide block moves up, matched with jaw drag-line directive wheel one by jaw drag-line one and matched with jaw drag-line directive wheel two by jaw drag-line two, thus utilizing jaw drag-line one and jaw drag-line two to pull the relatively close mobile formation clamped condition of the flat jaw of left plate formula jaw and the right side；When the clipping chuck of flexible cable tensioning is in clamped condition, the reseting pressuring spring between the flat jaw of left plate formula jaw and the right side is compressed for a moment, is in compressive state；

Described 4th) in step, the control clipping chuck of flexible cable tensioning is in open configuration is stretched out by the piston rod of control clamping cylinder, under the restoring force effect of reseting pressuring spring one, the flat jaw of left plate formula jaw and the right side moves along jaw moving leader towards the direction that is located remotely from each other and to realize.
