Problems solved by technology
[0004] The disadvantage of the currently used hydraulic push rod device is: due to the limitation of the space of the place of use, the length of the entire hydraulic push rod device is limited, thereby limiting the length of the piston rod, that is, limiting the stroke of the piston rod, making the entire hydraulic push rod The length of material that can be pushed by the rod device is limited
