Beschreibung
Zusammenfassung:	A quick rebound and compression type oil cylinder packer, comprising: a central pipe (1), a hydraulic pushing mechanism (2), a deformation expansion hole sealing mechanism (3), an upper connecting pipe (4), and a lower connecting pipe (5). The hydraulic pushing mechanism and the deformation expansion hole sealing mechanism are both of a concentric circle structure with the central pipe and are sleeved on the central pipe; the upper connecting pipe and the lower connecting pipe are respectively connected to the upper end and the lower end of the central pipe and implement self-sealing; the upper connecting pipe and the lower connecting pipe are respectively used for connecting a high-temperature and high-pressure gas emission device and a pressure relief device; the hydraulic pushing mechanism is located at the lower end of the upper connecting pipe, and the deformation expansion hole sealing mechanism is arranged at the lower end of the hydraulic pushing mechanism; a protrusion is provided at a position where
