The beneficial effects of the utility model are that:
1. the utility model discloses in control the motion of two cylinders through travel switch control gas accuse valve, through the tensioning of the skew control belt of the roller of rectifying, the reaction is rapid, and manpower, efficient are practiced thrift in real-time automatic correction.
2. The utility model discloses in pass through slide rail and slider with two rollers of rectifying and connect, realize two roller synchronous motion of rectifying, the telescopic link only needs to be connected with back shaft one end, and it is more convenient to maintain.
3. The utility model discloses in add the bolt and come the restriction to avoid the telescopic link extension overlength of cylinder, cause the excessive of rectifying.
