摘要： A tire puncture repair deivce comprises a hollow shank with a notched free end and an attached handle, a threaded conical penetrater having lugs on the bottom thereof, and an elongate resilient obturator fixed on one end to the bottom of the penetrater. The obturater is insertable within the bore of the shank wherein the lugs of the penetrater engages the notches thereon so as to rotate therewith. The penetrater and obturater are held in place by a spring loaded catch lever hingedly attached to the shank which engages a recess in the obturater through an opening in the shank. After penetration of a puncture the obturater is released by depressing the lever, and then ejected by moving a slide member, having a piston in abutment with the free end of the obturater, forward. The shank is subsequently extracted from the tire wall leaving the obturater therein to seal the puncture.
