PROBLEM TO BE SOLVED: To provide a spanner assisting tool allowing use of various L-form wrenches with one spanner and capable of turning a bolt easily. SOLUTION: Through this assisting tool 1, a quick spanner 20 and L-form hexagonal wrench 30 are coupled together. A socket 11 is formed over the assisting tool 1, and a rectangular or polygonal blind hole 111 is formed at the top of the socket 11 while a fixing seat 12 is formed on the eccentric side face of the bottom part in such a way as extending downward. A stepped hole 121 is formed in one side face of the seat 12 perpendicularly to the axis of the socket and provided with a plurality of hexagonal holes having different size, and two grooves 1211 are formed symmetrically at the two side faces of the stepped hole 121. A joint for the quick spanner 20 is attached to the blind hole 111, and L-form hexagonal wrench 30 is inserted into the stepped hole 121, and if the wrench 30 is turned by the spanner 20, the bolt can be turned easily.
