[0002] The hydraulic cylinder is a transmission method that uses liquid as the working medium for energy transmission and control. Its quality directly determines the performance of the entire system. Since hydraulic cylinders that have not been tested for rated pressure often fall back automatically or fail to reach the specified lifting weight at the construction site, hydraulic cylinders must be factory tested to meet the use requirements before they are officially put into use. For example, as shown in a hydraulic cylinder production top-to-top test device with Chinese patent application number CN202122799621.9, multiple groups of hydraulic cylinders are placed in a protective box and a tempered glass cover, which are symmetrically distributed to facilitate top-to-top tests. The hydraulic cylinders are separated by partitions, and the protective box and tempered glass cover are used to separate the hydraulic cylinders to avoid equipment failures causing harm to operators. At the same time, the hydraulic cylinders are fixed by latches and bolts, and disassembly and assembly are quick and convenient, effectively improving work efficiency.

[0003] However, due to the lack of a storage device for the mounting seat, after the hydraulic cylinder experiment is completed, the hydraulic cylinder is quickly removed from the mounting seat, which will expose the mounting seat above the base. The exposed mounting seat will not only affect the safety of the user, but also make it inconvenient to organize the base. Utility Model Content
