Portable safety belt fixing device

The invention relates to a portable safety belt fixing device which comprises first angle steel, second angle steel, third angle steel, bolts, nuts and steel bars. Wherein the first angle steel and the second angle steel are vertically arranged in parallel, a steel bar is connected between one ends of the two angle steels, a third angle steel is connected between the two angle steels at the lowerpart of the steel bar, and a gap is reserved between the steel bar and the third angle steel at the lower part; at least two through holes are formed in the first angle steel, bolts penetrate throughthe through holes respectively and then are fixed through nuts, and steel bars are transversely welded to the outer ends of the bolts respectively. And at least one through hole is formed in the second angle steel. The device is convenient to carry and install; the device can be repeatedly used, and cost is saved; safety belts can be conveniently tied and hung by edge construction workers, and thepersonal safety of the con
