ABSTRACT:
In a rotatively operating tool, a lever (5) having a head (4) at its tip end is turnably connected to a handle (6) provided at its tip end with a lower jaw (12). The head (4) is provided with an upper jaw (7) brought into engagement with an engaging surface (2a) of a bolt head (2). A spring (14) is mounted between the lever (5) and the handle (6) for biasing the lever (5) to turn it in a direction of abutment of a stopper face (11) of the lever (5) against the handle (6). When the handle (6) is turned in one direction, the lower jaw (12) at the tip end of the handle (6) is brought into abutment against an engaging surface (2b) of the bolt head (2), whereby the bolt head (2) is clamped between the lower jaw (12) and the upper jaw (7). When the handle (6) is turned in an opposite direction, it is brought into a state in which the clamping of the bolt head (2) is canceled. Even when the lever (5) is turned against a biasing force of the spring (14), the bolt head (2) is clamped between the upper jaw (7) and the lower jaw (12). Thus, it is possible to provide a rotatively operating tool having a simple structure, which is designed so that a rotatively operated member such as a bolt can be rotated in one direction and even in an opposite direction as required by the reciprocally turning operation of the tool.
