Beschreibung
Zusammenfassung:	The invention relates to a saw-toothed packing sealing device which comprises a rubber body (1). The rubber body (1) is in a long strip shape, the cross section of the rubber body (1) is circular, sawteeth are arranged on the edge of the rubber body (1), and a plurality of nylon wires (2) are longitudinally buried in the rubber body (1) in parallel. Packing is in a long strip shape, the cross section of the packing is in a saw-toothed shape, the device is used on an oil well, the effect is quite remarkable through field tests of more than 1,000 rod pumped wells, the service cycle of the packing is prolonged by three times, abrasion of a polished rod is reduced by 30 percent, the labor intensity of staff is reduced, work efficiency is improved, and it is guaranteed that crude oil extraction is carried out smoothly.
