[0002] In the mechanical processing industry, as an important mechanical component, the connecting rod is widely used in fields such as engines and transmission systems. The processing accuracy and efficiency of the connecting rod directly affect the performance and reliability of the whole machine. Therefore, during the processing of the connecting rod, it is necessary to effectively fix the connecting rod to ensure the processing accuracy and efficiency.

[0003] The existing patent (publication number: CN210650377U) discloses this fixing device for connecting rod processing. By setting a base, a first arc plate, a second arc plate, a motor, a threaded nut, and a threaded column, the threaded nut moves leftward under the action of the threaded connection with the threaded column, so that the threaded nut can drive the second arc plate to move leftward and contact the connecting rod body, enabling the first arc plate and the second arc plate to effectively fix the connecting rod body. It is not necessary for the staff to use bolts to press multiple pressing plates on the connecting rod body, which is very convenient for fixing the connecting rod body, improves the processing efficiency, and reduces the work intensity of the staff. However, in modern mechanical processing, it is often necessary to process the connecting rod workpiece at multiple angles and positions. After the connecting rod is fixed by this fixing device, if it is necessary to change the processing position or direction, the connecting rod must be completely released first, readjusted, and then fixed. This process not only takes time but also affects the processing efficiency. Content of the Utility Model
