Filler piece mounting assembly for lifting column and lifting column

A filler piece mounting assembly for a lifting column, comprising:

• a first casing;
• and
• a second casing, slidable within the first casing,
• a plurality of resilient filler pieces fixed to a fixing ring, the plurality of resilient filler pieces and the fixing ring are disposed outside an outer wall of the second casing and axially fixed relative to the first casing,
• a fixed frame for fixing the plurality of resilient filler pieces is disposed at a front end of the first casing and movable relative to the first casing, the plurality of resilient filler pieces collectively define a first inclined surface that is disposed on an outside of the plurality of resilient filler pieces, the fixed frame comprises an extrusion part for extruding the first inclined surface to radially deform the plurality of resilient filler pieces so as to adjust a clearance between the plurality of resilient filler pieces and the second casing,
• wherein the fixed frame further comprises a connecting part,
• wherein the plurality of resilient filler pieces and the fixing ring are all disposed within the first casing,
• wherein a gap is defined between the extrusion part and the connecting part for clamping the fixed frame to the front end of the first casing, the connecting part is connected with an outer wall of the first casing, and the extrusion part extends into the first casing to press against the first inclined surface.
