Abstract
The utility model relates to the technical field of screwdrivers and especially relates to a labor-saving screwdriver high in screwing force. The labor-saving screwdriver high in screwing force comprises a handle and a cutter head rod. A rotation device is arranged behind the cutter head rod and is embedded into the front end of the handle. The handle is trapezoid. A rotation through hole is disposed in each of the left corner and the right corner of the handle. A positioning baffle plate is arranged between the rotation through holes of the left corner and the right corner. A double-end nut is disposed in each rotation through hole. Rotation handles sleeve and are connected above and below the double-end nuts respectively. Each rotation handle includes a handle upper plate and a handle lower plate, and two ends of the handle upper plate and two ends of the handle lower plate are tightly locked via the double-end nuts. The labor-saving screwdriver has a reasonable structure and is convenient to use. The rotation handles that can rotate toward two sides are disposed behind the handle of the screwdriver, so that bearing points of the handle can be changed when the screwdriver is in use, and thus screwing force of the handle is increased.
