置。 A screw type jacking device consisting of a worm, a worm wheel that meshes with the worm, and a lifting rod that is screwed into the worm wheel and moves up and down as the wheel rotates, which transmits rotation to a driven gear fixed to the lower end of the worm shaft. A manual gear is provided, and a sprocket rotatably driven by a chain is loosely fitted to the upper end of the worm shaft, and the engagement between the manual gear and the drive gear is achieved by the vertical movement of a switching rod mounted on the housing of the jacking device so as to be able to move up and down. This screw-type jacking device is configured to engage and disengage a worm shaft and a sprocket using a clutch during disengagement and disengagement.
