[0002] The piston rod, also known as the piston pin, is an important part inside the engine. It is located between the piston and the crankshaft, connecting the piston to the crankshaft. One end of the piston rod is connected to the piston and fixed by the piston pin, and the other end is connected to the crankshaft and connected by the crankpin. The main function of the piston rod is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft. It plays a role in transmitting force and bearing load during the working process of the engine.

[0003] However, in the prior art, the existing piston rod and crankshaft are connected in a straight fixed manner, and the staff can only fix them by using a piston pin. This straight connection method limits the use of the piston rod in actual use, and the piston rod cannot be used in more different scenarios, which reduces its practicality in actual use. Therefore, we provide a method for adjusting the installation of the piston rod. Utility Model Content
