[0040] The working principle and use process of the utility model: before using the refrigerator compressor, the compressor body 100 is first fixedly installed at the internal installation position of the refrigerator through the fixing bottom plate 105. When the compressor body 100 is used after being fixedly installed, the suction port 107 is connected to the suction pipe, the discharge port 103 is installed with the discharge pipe, the terminal 108 is connected to the wire and the compressor body 100 is powered on, so that the compressor body 100 can perform refrigeration operation on the refrigerator during operation;

[0041] Then, before the compressor body 100 is fixedly installed for use, the clamping ring 1011 can be clamped in the inner surface of the clamping groove 1012, and the sealing ring 1013 can contact the inner surface of the clamping groove 1012, so that the cover 101 and the main body 102 are sealed and clamped together. After the sealing is engaged, the internal thread rotating wheel 1028 is rotated again at the end of the screw-in threaded rod 1027. When the internal thread rotating wheel 1028 rotates at the end of the screw-in threaded rod 1027, it drives the screw-in threaded rod 1027 to screw in and move. The screw-in threaded rod 1027 moves and drives the moving push plate 1025 to move inside the moving groove 1026. The moving push plate 1025 moves and drives the clamp head 1023 The movable clamp is engaged in the inside of the clamp hole 1024. After the clamp head 1023 is engaged and installed, the elastic block 1022 is deformed again to strengthen the elastic pressure of the clamp head 1023, which is convenient for reinforcing the sealing installation of the machine cover 101 and the main body 102.

When the compressor body 100 is used for a long time and causes an internal fault and needs to be repaired, the machine cover 101 is disassembled and repaired by the opposite operation, and the disassembly and assembly repair operation does not require the help of external disassembly and assembly tools. The disassembly and assembly operation is simple and convenient, and can be directly operated by hand, thereby improving the convenience of disassembly and assembly when the compressor body 100 is fixedly installed on the refrigerator and fails to be used;

[0042] Finally, when the compressor body 100 is fixedly installed on the refrigerator, before the terminal 108 is connected again, the connecting wire is passed through the through hole 1082 and is inside the inner connecting plate 1084, and the fixed installation cover 1081 is fixedly installed on the top of the machine cover 101 by screws. After the fixed installation cover 1081 is fixedly installed, the threaded moving rod 1083 is rotated to drive the extrusion card plate 1085 to move. When the extrusion card plate 1085 moves, it drives the support slide bar 1086 to slide inside the support slide groove 1087, so that the extrusion card plate 1085 is inside the through hole 1082 and moves stably. The connecting wire is moved and squeezed on the surface of the connecting wire, so that the connecting wire can be reinforced inside the through hole 1082, and the end of the connecting wire can be reinforced and installed after the terminal 108 is connected. When the compressor body 100 is fixedly installed on the refrigerator and used, when the connecting wire is touched by an external object and causes the connecting wire to be subjected to tension, it is not easy to cause the end of the connecting wire and the terminal 108 to be loosened or broken due to the tension, thereby improving the enhanced fixity of the terminal 108 connection installation of the compressor body 100 fixedly installed on the refrigerator, so that the compressor body 100 can be stably installed and used.
