A tool includes a head member and two pivotably connected rods. The head member has a passage defined transversely therethrough and the rods extends through the passage. A driving head is connected to the head member. When the pivotal portions of the two rods are located within the passage, the two rods form a straight and solid bar. When the pivotal portions of the two rods are located outside of the passage, the two rods are pivotable relative to each other so as to be used in different situations. |
