After the electric cylinder is produced, some tests need to be performed on the electric cylinder to detect the performance of the electric cylinder.

[0003] During the use of existing electric cylinders, movement under negative pressure is very common. In order to ensure the pushing stability of the electric cylinder, the pushing force of the electric cylinder needs to be tested. The commonly used detection method is to install a weight block to detect the pushing stability. The electric cylinder moves.
