Jack for earth retaining work that is easily extendable by an electric screwdriver or a wrench.
It is safe because it can be installed/removed from the above ground by using a dedicated working bar without entering into a drilled place.
With the gear structure, there is no concern about shrinking the jack due to getting wet like the water pressure type.
