When the tail pipe into the design position, according to the normal procedure to sit hanging, re-buckle, 
cementing, after the pressure, the lifting drill to feed into the tool on the block stopper, sitting back to the 
barrel The upper face, the lower drill, shear pin, plastic tube expansion under the action of external force, 
the upper casing and the back to form an effective seal between the cylinder.
