In addition, the use of the snap connection mechanism ensures the tightness and reliability of the connection, and avoids the problem of loosening caused by vibration or pressure changes. The threaded connection provides a stable fixing method, ensuring the precise alignment between the oil suction pipe 2 and the crankshaft 1, thereby ensuring the normal operation of the compressor and extending its service life. This design not only simplifies the assembly process but also reduces maintenance costs, providing users with a more cost-effective solution.

[0020] Furthermore, the connecting member 3 has a crankshaft connecting end 4 and an oil pipe connecting end 5. A connecting groove 6 is provided on the connecting member 3, which passes through the crankshaft connecting end 4 and the oil pipe connecting end 5. The cross-sectional shape of the connecting groove 6 is arranged in a stepped manner. The connecting groove 6 has a first groove portion 7 located at the crankshaft connecting end 4 and a second groove portion 8 located at the oil pipe connecting end 5. The inner diameter of the first groove portion 7 is larger than the inner diameter of the second groove portion 8. The crankshaft 1 and the oil suction pipe 2 extend into the first groove portion 7 and the second groove portion 8, respectively, to connect with the connecting member 3. Specifically, in this embodiment, the stepped design of the connecting groove 6 allows crankshafts 1 and oil suction pipes 2 of different diameters to respectively cooperate with the corresponding groove portions of the connecting member 3, thereby achieving precise positioning and a tight connection. The inner diameter of the first groove portion 7 is larger than the inner diameter of the second groove portion 8, which ensures the stability of the crankshaft connecting end 4 while allowing the connecting end of the oil suction pipe 2 to remain stable when subjected to pressure or vibration. Furthermore, this design facilitates quick and accurate insertion of the crankshaft 1 and oil suction pipe 2 into their respective grooves when repairing or replacing the oil suction pipe 2, further improving maintenance efficiency and ease of operation. With this structure, the connector 3 of the assembled compressor oil suction pipe 2 not only ensures connection reliability but also simplifies assembly and maintenance, providing a strong guarantee for the long-term stable operation of the compressor.
