Claim:
1. A connector, including: a rod body, two ends of the rod body respectively having an assembling portion for a tool head to be assembled thereto and an insertion groove, the insertion groove having at least one restraining section and at least one radially-enlarged section which are neighboring to each other and a receiving section, a smallest radial dimension of the at least one radially-enlarged section being greater than a largest radial dimension of the at least one restraining section, the rod body formed with at least one through hole which communicates with the receiving section; at least one detent, received in the at least one through hole and partially projectable into the insertion groove; an abutting assembly, being positioningly restrained relative to the rod body and sleeved outside the rod body and the at least one detent being sandwiched between the abutting assembly and the rod body, the abutting assembly being movable relative to the rod body between an abutting position and a releasing position, an inner side of the abutting assembly having a protrusion and a recess; a first elastic member, abutting against between the rod body and the abutting assembly and biasing the abutting assembly toward the abutting position normally; a connecting rod, an end thereof being adjustably inserted into the insertion groove, the other end thereof for connection with a rotational driving tool, the connecting rod further including at least one abutting section which radially protrudes thereon and an annular groove, each said abutting section being non-round and abuttable against an inner wall of the restraining section circumferentially, the connecting rod being axially movable relative to the rod body to a comoving position or an idling position; wherein when the abutting assembly is in the abutting position and the connecting rod is in the comoving position, the protrusion abuts against the at least one detent, the detent partially protrudes into the annular groove to restrain an axial movement of the connecting rod relative to the rod body, and each said abutting section corresponds to and circumferentially abuts against the inner wall of one said restraining section; when the abutting assembly is in the releasing position and the connecting rod is in the idling position, the recess allows the at least one detent to retreat thereinto, the connecting rod is axially movable relative to the rod body, and each said abutting section corresponds to one said radially-enlarged section so that the connecting rod is rotatable relative to the rod body.
