Through rotating first threaded rod and rising, hydraulic oil in the first oil groove of first threaded rod top surface extrusion, hydraulic oil promote first slide bar and outwards slide along first stop collar to make the distance increase between first drive wheel and the driving disc axis. Similarly, counter-rotating the first threaded rod downward may reduce the distance between the first drive wheel and the axis of the drive disk.
