In order to keep the stress balance of stripper, the quantity of described material returned screwing through hole and described rubber column locating hole is 4.
Further, described rubber column locating hole is circular or square, and corresponding described rubber column is cylindrical or square column type.
In order to avoid oil level gauge moves left and right in die, described die is provided with two pairs of backing pins, adds man-hour, the blade of oil level gauge is placed between backing pin.
In order to ensure the blade balance of oil level gauge, the right side of described die being provided with location supporting plate, this location supporting plate is provided with block.
Remarkable result of the present utility model is: by improving the reset mode of stripper, to overcome in prior art because the spring fatigue effect defect that causes service life of equipment shorter, while extension device service life, improves the production efficiency of equipment.
