The invention provides a force-enhancing screwdriver and relates to a screwdriver. A cutter bit (10) is arranged at the lower end of a cutter bar (8); the lower end of a thin bar (5) is fixedly connected to a cutter bar upper end (7) of the cutter bar; the lower part of the thin bar is arranged in a perforation (13) which is formed in the middle of a pressing bar or a rotating handle (6); inserting holes (11) are formed in the surface of the upper part of the pressing bar or the rotating handle on the two sides of the perforation respectively; an annular handle (1) is arranged at the upper end of the thin rod; thumb pressing sheets (3) extending outwards are arranged on the two sides of the lower part of the annular handle respectively; and inserting columns (4) corresponding to the inserting holes (11) of the pressing bar or the rotating handle are arranged on the surface of the lower part of the annular handle. The force-enhancing screwdriver can be used for installing and dismounting rusted screw spikes easily through the coordination of the pressing bar or the rotating handle and the annular handle as well as the thin bar and the cutter bar.
Description
【Technical field】 [0001] The invention relates to a screwdriver, in particular to a booster screwdriver. 【Background technique】 [0002] Known, screwdriver is widely used in machining, equipment maintenance, parts assembly industry as the loading and unloading tool of screw, but a lot of screw are owing to carrying out maintenance for a long time, and rust phenomenon often occurs, makes dismounting comparatively difficult, and existing screwdriver They all have a cylindrical handle at the rear and a screwdriver head at the front. The usable force is relatively limited when used, especially after the screws are rusted, this kind of screwdriver is basically useless. 【Content of invention】 [0003] In order to overcome the deficiencies in the background technology, the present invention discloses a booster screwdriver, which can easily load and unload rusted screws through the cooperation of a pressing rod or a rotating handle, a ring handle, a thin rod, and a knife rod.
