[0002] A compressor usually includes a shell, a motor arranged in the shell, a crankshaft driven by the motor, a cylinder seat with a cylinder, a piston arranged in the cylinder, and a connecting rod connecting the piston and the crankshaft. The connecting rod transmits the driving force of the crankshaft to the piston, allowing the piston to reciprocate in the cylinder. Therefore, the connecting rod is particularly important for the operation of the compressor.

[0003] After searching, the patent number is CN217401088U, which discloses a compressor piston connecting rod assembly, which is convenient for oil immersion of the connection between the bushing and the piston. The first oil outlet hole transports the lubricating oil to the oil channel, and the inner cavity of the connecting rod bearing and the movable bearing is immersed in oil through the second oil outlet hole; in addition, since the connecting rod bearing and the movable bearing are arranged to be split, it is convenient for loading and unloading and maintenance. However, the existing compressor connecting rod is usually an integrated structure when in use. When the connecting rod is partially damaged, the entire connecting rod needs to be replaced, which is more wasteful of resources and economy. Utility Model Content
