[0002] In order to ensure the smooth operation of various machines, it is necessary to perform regular maintenance on the hydraulic cylinders working in various machines. Usually, the hydraulic cylinders separated from the machines are placed on the maintenance platform, and the piston rods inside are disassembled to detect the wear degree of the internal sealing rings. Since some hydraulic cylinders are cylindrical in shape, they cannot be placed stably on the maintenance platform. Although the existing maintenance platform has a fixing device, which usually fixes one end of the hydraulic cylinder, it lacks an adjustment mechanism and cannot be applied to hydraulic cylinders of different diameters, especially those with larger diameters.
