[0022] Specifically, a driving rod 2 is rotatably connected to the fixed plate 1, a connecting rod 201 is fixedly welded at the bottom of the driving rod 2, and a retractable linkage rod 202 is fixedly welded on the connecting rod 201, so that when the driving rod 2 rotates, it can drive the connecting rod 201 and the linkage rod 202 to rotate around the top of the driving rod 2, and driving frames 301 are fixedly welded at both ends of the linkage rod 2, and the driving frame 301 is fixedly welded to the side of the eccentric wheel 3, so that when the driving rod 2 rotates, the eccentric wheel 3 and the driving frame 301 will also rotate accordingly, thereby changing the position of the eccentric hole on the eccentric wheel 3, and a crankshaft connecting rod mechanism 5 is rotatably connected in the eccentric hole of the eccentric wheel 3, and the crankshaft connecting rod mechanism 5 consists of a main shaft 501, a crank 502, a crank 503, a connecting rod shaft 504 and a connecting rod piston 505. A motor 4 is fixedly connected to one end of the main shaft 501, and the motor 4 is fixedly mounted on the driving rod 2, so as to provide support for the motor 4. When the driving rod 2 rotates, it will drive the mounting frame 203 to rotate. At the same time, the eccentric wheel 3 will drive the crankshaft connecting rod mechanism 5 to change its position, so that the main shaft 501 and the motor 4 will change their positions at the same time. The connecting rod piston 505 is rotatably connected to the crank 503, and the crank 503 is fixedly connected to the crank 502. The crank 502 is fixedly connected to the main shaft 501. Since the crank 502 and the crank 503 are staggered up and down, when the main shaft 501 rotates, the connecting rod piston 505 on the crank 503 will move up and down, thereby completing the compression work. The crank 502 and the crank 503 in the middle are connected by a retractable connecting rod shaft 504, so that the gap between the connecting rod piston 505 can be changed by the extension and retraction of the connecting rod shaft 504, thereby improving the applicability of the device to the compression work of different compressors.

[0023] The working principle and use process of the utility model are as follows: first, when in use, start the motor 4, control the main shaft 501 to rotate in the eccentric hole of the eccentric wheel 3, and then drive the connecting rod piston 505 to start lifting and lowering for compression. When the compression depth of the connecting rod piston 505 needs to be changed, control the driving rod 2 to rotate a certain angle, so that the driving rod 2 drives the connecting rod 201 and the linkage rod 202 to rotate around the top of the driving rod 2, thereby driving the driving frame 301 and the eccentric wheel 3 to rotate, and then change the position of the eccentric hole on the eccentric wheel 3, so that the crankshaft connecting rod mechanism 5 will change position with the eccentric hole on the eccentric wheel 3, and the main shaft 501 rotates and is connected in the eccentric hole of the eccentric wheel 3, so that the crankshaft connecting rod mechanism 5 will not stop running due to the rotation of the eccentric wheel 3, thereby changing the compression depth of the connecting rod piston 505, thereby improving the applicability of the device to the compression requirements of different compressors.
