The invention discloses a transfer frame for assembling a bus control mechanism. The transfer frame for assembling the bus control mechanism comprises a first frame and a second frame, wherein a universal wheel is fixed on one surface of the first frame; limiting convex blocks are respectively fixed on the two end surfaces of the first frame; baffles are fixed on the two sides of the other surface of the first frame; a material box is fixed on one surface of the second frame; cantilever supporting rods are respectively fixed on the two side surfaces of the second frame in parallel; and the first frame and the second frame are integrally connected with each other through a support. According to the invention, the transfer tool framework, which is designed for a mounting process of the bus control mechanism, is provided with a structure of a relevant tool for mounting the control mechanism; and moreover, as structures, such as a protective backing plate layer, an anti-moving limiting groove and the like, designed for the control mechanism, are arranged and a limiting structure is also arranged, the stability of the tool is improved.
