These chain plates are connected together through a pin shaft to form the main part of the chain, and the adjacent chain plates can rotate relatively flexibly, which enables the chain to smoothly transmit on the sprocket.

[0003] The plate chain is connected by a plurality of chain links through a pin shaft. The clamping test can simulate the external forces, such as tension and pressure, that the chain is subjected to in actual use, and test whether the connection between the chain links is firm and other issues, thereby ensuring the stability and reliability of the overall structure of the chain and preventing dangerous situations such as chain link falling off during use.

[0011] As a further description of the above technical solutions:

[0012] The upper end of the clamping body is connected with the testing machine through internal threads.

[0013] As a further description of the above technical solutions:
