Abstract: A drive tool comprises a socket body, which has a drive end for coupling to a handle and a socket end for coupling to a bolt or nut. The drive end defines a drive opening for being engaged with a drive lug of the handle. The drive opening is defined by at least two sets of engagement surfaces, all sets of engagement surfaces being evenly distributed with respect to a central line of the socket body and being spaced at intervals of an angle, each set of engagement surfaces being configured to define a sub-opening that is matched with the drive lug of the handle so that the drive lug of the handle can be engaged with each set of engagement surfaces. Thereby, the handle can be coupled to the drive tool more easily so as to facilitate an operation.
