1 Release button (Inner ring)
2 Mark Point(Outer Ring)
Two support bearings are installed on the lifting arm to support
the gas fluctuation axis equipped with paper rolls. The bearing is
composed of the outer ring and the inner ring. The bearing is fixed
on the lifting arm through the outer ring. The inner ring can rotate
and push along the shaft. Only when the release button on the inner
ring is aligned with the mark point on the outer ring, the release
button can be pressed to push the inner ring of the two bearing
down/lock the gas fluctuation axis to the outward / inner side
respectively. The design of bearing can prevent the accidental fall
off of the gas fluctuation axis.
