[0002] Cylinder liners are divided into dry cylinder liners and wet cylinder liners. Compared with dry cylinder liners, wet cylinder liners have slightly thicker cylinder liners, but have stronger heat dissipation capabilities. After a certain period of use, the cylinder liners of the engine will be damaged due to wear and tear, and the cylinder liners need to be replaced during maintenance. The original method of removing the cylinder liners was to use a hammer and a steel rod to knock the cylinder liners out of the cylinder body, which easily damaged the cylinder body.

[0003] A Chinese patent application with application number CN201820328852.7 discloses a pneumatic hydraulic internal combustion engine cylinder liner puller, in which an air pump air pipe joint is connected to an air pump through an air pipe.
