FIELD: machine building.
SUBSTANCE: present invention discloses a basic mechanism of a single post withstanding unloading at low pressure, including a bottom base plate and two wedge-like support units, where one of the wedge-shaped support units serves as a fixed wedge-like support unit and is welded to the base bottom plate, and the other of the wedge-like support units serves as the movable wedge-like support unit and is connected to fixed wedge-like support unit by means of threaded rod and nut.
EFFECT: present invention can efficiently unload a single post at low pressure or remove a single post by a negotiated method, has a simple structure, is easy to use, has a good utilization factor, overcomes the technical problem, due to which it is difficult to unload a single post at low pressure in this technical field and is widely used in this technical field.
