[0002] Cylinder liner is the abbreviation of cylinder liner. It is embedded in the cylinder barrel of the cylinder body and forms a combustion chamber together with the piston and cylinder head. Cylinder liners are divided into two categories: dry cylinder liners and wet cylinder liners. The cylinder liner whose back does not contact the cooling water is called a dry cylinder liner, and the cylinder liner whose back contacts the cooling water is a wet cylinder liner. The dry cylinder liner is thinner, simpler in structure, and easier to process. The wet cylinder liner directly contacts the cooling water, so it is beneficial to the cooling of the engine and the compactness and lightness of the engine. When repairing the engine cylinder liner, it needs to be pulled out with a cylinder liner pulling tool.

[0003] In the prior art, when using the limit assembly to move and fit the inner wall of the cylinder liner, it is necessary to manually turn two screws in sequence to drive the limit plates to squeeze the cylinder liner, and then pull the limit assembly to pull out the cylinder liner. This operation method is time-consuming and labor-intensive, and reduces work efficiency. Utility Model Content
