[0021] The buffer structure includes a mounting plate 11, one side of the mounting plate 11 is fixedly connected to a plurality of spring threes 12, the other ends of the plurality of spring threes 12 are fixedly connected to the same buffer plate 13, and the buffer plate 13 is provided with a rubber pad 14. When subjected to force, the rubber pad first contacts the inside of the compressor to prevent rigid collision. The spring three 12 can buffer the force, thereby protecting the main shaft.

[0022] The mounting plate 11 is fixed to the main shaft 1 and the main shaft 2 by fixing bolts respectively, and the mounting plate can be disassembled and assembled by the fixing bolts, so that maintenance and replacement are convenient.

[0023] The main shaft 1 is provided with a threaded hole 15 matching with the bolt and nut 10, the threaded hole 15 is communicated with the cross slot 4, and the bolt and nut are threadedly connected with the threaded hole 1, so as to realize the connection and fixation between the fixing sleeve and the main shaft 1.

[0026] Working principle:

[0027] When the utility model is in use, the length of the main shaft can be adjusted by adjusting the extension length of the connecting shaft 3 extending out of the cross groove 4, thereby facilitating the installation of the main shaft of the automobile air-conditioning compressor. During installation, the main shaft 2 is pushed to make the connecting shaft 3 slide into the cross groove 4, shortening the length of the main shaft, thereby installing the main shaft at a specified position. After aligning the position, the main shaft 2 is pulled to make the connecting shaft 3 gradually extend out of the cross groove 4. After extending a certain length, the fixing sleeve 9 is aligned with the main shaft 1 and the main shaft 2, and the fixing sleeve 9 is fixed to the main shaft 1, the main shaft 2 and the connecting shaft 3 by bolts and nuts 10, thereby fixing the main shaft, allowing the main shaft to be used normally and facilitating installation. When the connecting shaft 3 slides in the cross groove 4, the fixed sleeve 9 slides on the surface of the main shaft 1 and the main shaft 2. After adjustment, the fixed sleeve 9 can be restored to its original position under the elastic force of the spring 1 7 and the spring 2 8, and stably sleeved on the surface of the main shaft 1 and the main shaft 2, so as to more conveniently realize the fixation between the fixed sleeve 9 and the main shaft 1, the main shaft 2 and the connecting shaft 3. When the air-conditioning compressor is working, it drives the main shaft to rotate. The buffer plate 13, the rubber pad 14 and the spring 3 12 can protect the outer side of the main shaft 1 and the main shaft 2. When subjected to force, the force can be buffered to a certain extent to avoid direct contact with the inside of the compressor to cause a large impact and damage, thereby increasing the service life and ensuring the normal operation of the automobile air-conditioning compressor.
