Abstract:
A tool connecting rod of the present invention includes a barrel and a rod. A resilient unit and a retainer are disposed between the barrel and the rod. Both of an inner wall of the barrel and a body portion of a pushing member are formed with at least two stepped recesses respectively. As such, the structure of the tool connecting rod is simple so that a tool bit assembles on and detaches from the present invention rapidly.
