Summary:The utility model designs an extension rod mechanism of a tightening tool. A connecting device is fixedly connected to the tightening tool; a shaft sleeve is fixed below the connecting device; a telescopic extension structure is arranged in the connecting device and the shaft sleeve on a preset axis of the connecting device and the shaft sleeve; and a tightening output shaft of the tightening tool is connected with a telescopic extension structure. The bolt tightening tool has the advantages of being simple in structure, easy to operate, capable of enlarging the space between the tightening tool and a workpiece, convenient to grab bolts and tighten the bolts and the like. The technical problems that in the prior art, in the engineering machinery assembling process, during assembling, the bolt mounting position is often far away from the upper surface of a workpiece, a standard tightening tool interferes with the workpiece, tightening operation cannot be conducted through the tightening tool, and use of a tigh
