For example, when the body diameter of the compressor 10 is small and/or the height of the upper cover is low, the relay sleeve 22 can be fixed on the sleeve part 211, and the relay sleeve 22 does not participate in the packaging of the compressor 10, and the main working part is the sleeve part 211, and when the body diameter of the compressor 10 is large and/or the height of the upper cover is high, the relay sleeve 22 can be used for moving downwards, and the distance between the bottom of the relay sleeve 22 and the bottom plate 11 is smaller than the distance between the bottom of the sleeve part 211 and the bottom plate 11, so that the relay sleeve 22 is still fixed on the sleeve part 211 and participates in the packaging of the compressor 10, thereby forming a fixed cavity with higher height and larger diameter, and further improving the universality of the packaging structure 100 and reducing the packaging cost. In order to ensure that the relay sleeve 22 can reliably and stably limit and fix the top of the compressor 10, a limit clamping groove 222 is preferably provided at the bottom of the relay sleeve 22 to limit and fix the top of the compressor 10.

In addition, the height of the relay sleeve 22 is between 30mm and 60 mm, and the size design can ensure that the relay sleeve 22 and the sleeve part 211 can have a stable connecting structure, can also ensure that the relay sleeve 22 effectively positions and supports the top of the compressor 10, can also ensure the structural strength of the relay sleeve 22, and can avoid the space occupied by the packaging structure 100 due to the excessively high height of the relay sleeve 22, thereby being convenient for storage and transportation of packaged products using the packaging structure 100.

In this embodiment, since the sleeve portion 211 preferably extends outside the main body of the base plate 11, in order to increase the structural strength of the main body of the base plate 11 and the structural strength between the sleeve portion 211 and the main body of the base plate 11, the reinforcing ribs 213 are provided on the main body of the base plate 11 and between the main body of the base plate 11 and the sleeve portion 211.

Preferably, there is a space between two adjacent fixed laths 32 to reduce the weight of the compression plate 3. The fixing strip 32 can be used to increase the overall structural strength of the pressing plate 3and also serve to connect a plurality of pressing strips 31. The pressing plate 3 can prevent the cover plate 21 from being extruded by the later-stage packaging belt, so that the cover plate 21 is protected, and the cover plate 21 can be recycled, so that the packaging cost is reduced.

Further, the angle a between the top surface of the platen 3 and the side surface of the platen 3 is preferably between 60 ° and 85 °, i.e. the optimal inward tilt angle b of the side surface of the platen 3 is between 5 ° and 30 °.
