The invention relates to a multi-way valve rotation folding arm fixing mechanism of a drilling crane. The mechanism is characterized by comprising a stand column, a main arm, a secondary arm and a multi-way valve fixed panel, wherein the stand column is vertically arranged; the main arm and the secondary arm are horizontally arranged; a first end of the main arm is hinged to the upper end of the stand column; a second end of the main arm is hinged to a second end of the secondary arm; and a first end of the secondary arm is welded with the multi-way valve fixed panel. The mechanism is compact in structure, reasonable in design, flexible and variable, and can be adjusted according to the differences of construction environments and personal operation habits to prevent potential safety hazards caused by operators approaching the machine in the construction process and to prevent the mud splashing in loading/unloading of a drill rod.
