The utility model relates to a screwdriver, which comprises a cylindrical holder and a screw, wherein two cubic grooves are formed on the surface of the holder along the central axis direction, and a handle is inserted into the groove and in movable connection with one end of the groove. The handle can be pulled out from the groove by the user to form a right angle with the angle, and, at the moment, the two handles are on the same straight line and vertical to the holder. Then, the user can pull the handles by the thumb and the index finger to make clockwise and anticlockwise rotation, and the active force can be reduced due to the large moment, thereby saving physical strength. The utility model has advantages of simple structure, good appearance, wide application and low cost.

Description

Screwdriver

Technical field the utility model relates to a kind of repair outfit, especially a kind of screwdriver.

Technical background is well-known, screwdriver is people's the most frequently used instruments in live and work, but present screwdriver must people firmly rotate the competence exertion effect in use, uses screwdriver very difficult for the little crowd of strength, can't turn screw sometimes at all.Therefore in order to satisfy proprietary requirement, people are sought after a kind of labour-saving screwdriver and help people's head it off.

The summary of the invention the purpose of this utility model provides a kind of screwdriver, is used to solve consume the big problem of strength when the normal screws cutter uses.

For achieving the above object, the utility model screwdriver comprises handle of a knife and screw rod, handle of a knife is a cylindrical structure, offer two cube grooves along the handle of a knife central axis direction in its surperficial symmetry, a pair of flexible handle inserts groove respectively and flexibly connects with groove one end, and the junction is near the screw rod direction.

After adopting said structure, the user can normally use screwdriver to carry out work; In order to reduce active force, the user also can pull out two flexible handles in groove, because groove is a cube structure, both ends open is the plane, therefore handle and groove maximum meet at right angles, stop after handle and groove meet at right angles, this moment, two handles were in line, and vertical with handle of a knife, the user with thumb and forefinger break off with the fingers and thumb respectively handle suitable, be rotated counterclockwise, because moment strengthened, so active force reduces, for the user has saved muscle power.

The utility model has the advantages that: simple in structure, good looking appearance, be widely used, cheap, increase moment and reduce active force, for the user provides comfortable easy condition of work.
