Self-locking type cross arm insulating plate placing tool

The invention provides a self-locking type cross arm insulating plate placing tool, and relates to the technical field of cross arm mounting tools, and adopts the scheme that the self-locking type cross arm insulating plate placing tool comprises an insulating baffle, a self-locking sliding block is fixed on the insulating baffle, a first fixing frame and a second fixing frame are connected to the self-locking sliding block in a sliding manner, and a mounting groove for mounting a cross arm is formed in the self-locking sliding block. The tool has the advantages that the tool is simple in structure and convenient to operate, the cross arm is clamped through the first fixing frame and the second fixing frame, the cross arm can be rapidly installed, the working efficiency is improved, meanwhile, the labor intensity of workers is reduced, the cross arm can be detached only by lifting up the first fixing frame and the second fixing frame in the detaching process, and the work efficiency is improved. Convenience,
