Lift buffering structure

A lift buffering structure, comprising:

• a hollow column-shaped housing;
• a holding seat being immovably connected to an inner wall surface of the hollow column-shaped housing;
• an inner stem being disposed in the hollow column-shaped housing and slidably extended through the holding seat;
• an elastic element having an end connected to the inner stem and another end connected to the holding seat to limit a travel stroke of the inner stem;
• an abutting unit being disposed at one side of the holding seat opposite to the elastic element and having a width downward reduced gradually along a height direction of the hollow column-shaped housing;
• and
• an anti-slip unit, wherein the anti-slip unit includes a roller holder and two rollers, the roller holder fixedly connected to a lower end of the inner stem, the two rollers have a rotational shaft rotatably connected to the roller holder respectively, and the two rollers are respectively slidably along the axial direction of the inner stem and located between the abutting unit and the inner wall surface of the hollow column-shaped housing, and one lateral side of each rollers keeps contacting with the inner wall surface, and other lateral side of each rollers is gradually separated from the abutting unit or gradually brought to contact with the abutting unit.
