The utility model provides a broken inflation ware of use of tearing open of bushing pipe in oil pipe, this inflation ware includes pull rod (1), convex forked tail slide (2), semicircular slips (3) and semicircular stopper (4), pull rod one end is provided with the earrings and the other end is provided with toper direction head, the hookup has two mutual dislocation on the pull rod of the first orientation of edge toper direction, each other back to the convex forked tail slide that just has the inclination, relative another the convex forked tail slide of one of them convex forked tail slide is 180 configurations, the semicircular slips hookup that has concavity forked tail slide can freely be slided along it in convex forked tail slide, maximum cross -section end is through countersunk screw hookup semicircular stopper, and the ware that should expand can dwindle the internal diameter and get into oil pipe inside lining intraduct, makes in the slips chucking that disposes the bushing pipe on the inflation ware and pull out oil pipe with it under tensile force, has solved broken the tear problem of interior bushing pipe in oil pipe.
