The invention discloses a multi-angle adjusting instrument box mechanism, which comprises a fixed frame, a rotating frame, an adjusting frame, an instrument box supporting frame and an instrument box.The rotating frame comprises a first connecting shaft and a second connecting shaft which are parallelly arranged; the lower end of the first connecting shaft is movably inserted in the upper part ofthe fixed frame, and the rotating frame can rotate around a center shaft of the fixed frame; the lower end of the adjusting frame is movably inserted in the second connecting shaft of the rotating frame, and the adjusting frame can rotate around a center shaft of the second connecting shaft of the rotating frame; and the instrument box supporting frame is arranged on the back face of the instrument box in a fixedly connected mode, and hinged to the adjusting frame, and the instrument box can rotate around the hinge point to adjust the angle of the instrument box. Through combination adjustment of multiple bracket angles, the instrument box can be positioned at random within the left-right 180-degree space range; and by adjusting the instrument box within the vertical 90-degree range, theneeds of an operator for the optimal view of an operation panel under the two conditions of sitting and standing can be met.
