[0002] Chain cutting machine is a kind of equipment specially used for cutting materials, which is widely used in industries, construction, wood processing and metal processing. It usually uses chain as cutting tool, which is efficient, accurate and multifunctional. In order to verify the service life of the chain, it needs to be tested. Traditionally, the tensile strength of the chain is evaluated first, and then the wear of the chain is measured, and finally its service life is estimated.

[0003] The existing service life of the chain is mainly estimated, which is not convenient for actually verifying the service life of the chain in cutting different materials. Usually, when cutting, it is necessary to manually feed the material to be cut to the cutting position, and then manually adjust the cutting chain to contact the material to be cut for cutting. During the long-term chain cutting test, it is troublesome and time-consuming, and the operation effect is not good. For this reason, we propose a chain cutting test machine. Summary of the invention
