[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Enterprises involve conveyor lines in the processing and packaging of products, and conveyor lines use conveyor belts as power sources. In the actual production process, in order to improve production efficiency, conveyor lines are often designed to be in different heights or with a certain inclination angle. Therefore, conveyor belts not only need to adapt to different forms of conveyor lines, but also need to reduce the downtime of conveyor lines during conveyor belt maintenance and reduce production capacity losses. When repairing and replacing PU drive belts or bearings on existing conveyor belts, it is necessary to remove the bearings, sprockets, chains and other accessories on the frame to remove the drive shaft rollers. The disassembly and assembly structure is complicated and time-consuming.
