Disclosed is a defrosting machine column fixed support with an inclined flat leg, comprising a defrosting machine (1), a connecting support (2), a pedestal bolt (3), and a pedestal (4). The connecting support (2) is composed of an anti-tilting guide barrel (21), a fixed pillar (22), a rib plate (23), and a connecting plate (24). The pedestal (4) comprises a pedestal plate (41) and a flat leg (42). The pedestal bolt (3) is used for fixedly connecting the connecting support (2) with the pedestal (4). The pedestal plates are hit into the soil so as to solve digging difficulties and low efficiency of a small diameter mounting deep hole with high accuracy requirements； each pedestal plate is respectively vertically provided with two intersecting flat legs in an inclined mode, thus balancing forces in each direction and stabilizing the defrosting machine column； the holes on the pedestal plates can integrate the soils on the inner side and outer side and two sides into one body, thus stabilizing the defrosting machine； in addition, the connecting support is employed, and standard tubes replace conventional non-standard tubes, thus saving on material cost, and transport and storage are also convenient. The support is simple in structure, convenient to implement, can be applied on pebbled land, not only reduces labour intensity when mounting, but also improves the anti-sinking, anti-horizontal torsion and anti-tilting abilities of the defrosting machine column, improves defrosting machine work reliability, and improves mounting efficiency and economic benefits of the defrosting machine.L'invention concerne un support fixe de colonne de machine de dégivrage muni d'un pied plat incliné, comprenant une machine de dégivrage (1), un support de connexion (2), un boulon de socle (3) et un socle (4). Le support de connexion (2) est composé d'un cylindre de guidage anti-inclinaison (21), d'un pilier fixe (22), d'une plaque à nervure (23) et d'une plaque de connexion (24). Le socle (
