Disclosed is a variable sliding manhole safety guard. The variable sliding manhole safety guard according to an embodiment of the present disclosure includes an installation support part that is installed on an inner wall of a manhole to be installed and has a rail structure vertically extending by a predetermined length and configured to change a vertical position of a movement guide, the movement guide that is mounted on the rail structure to change a vertical position, has a structure vertically extending by a predetermined height, and is mounted on a safety fence in an integrated structure, the safety fence which is mounted on the movement guide in an integrated structure and includes a plurality of frames forming a cylindrical structure having an outer diameter corresponding to an inner diameter of a manhole entrance, and in which an openable entrance door is installed in an upper one surface thereof, a safety fence position fixing part which is mounted on an upper portion of the safety fence so that a stopping lever performs a rotational operation and in which a stopping member configured to fix a vertical height of the movement guide by the rotational operation of the stopping lever is mounted at a lower end thereof, and a ladder that is adjacent to the installation support part, is installed on the inner wall of the manhole, and has a structure extending from the manhole entrance to an inside of the manhole by a predetermined length. According to the present disclosure, a variable sliding manhole safety guard which can prevent a ground pedestrian from falling into a manhole in a state in which a manhole cover is open, can prevent accidents in which a worker falls into the manhole when the worker enters the inside of the manhole for the purpose of working inside the manhole, and can be installed and utilized only when necessary may be provided.
