Abstract

A screwdriver with a single force shank comprises a cylindrical screwdriver shank, the cylindrical force shank and a slotted screwdriver rod. The central point of the screwdriver shank is connected with one end of the force shank, the included angle between the force shank and the axis of the screwdriver shank is ninety degrees, and the screwdriver rod is cast in the end of the screwdriver shank connected with the force shank. The screwdriver with the single force shank is large in torsion, labor is saved when rusted and too tightly mounted screws are detached, and the screws are not easily damaged and are detached in a more labor-saving manner.

Description

technical field [0001] The invention relates to a mechanical maintenance tool, in particular to a single-handle screwdriver. Background technique [0002] At present, the known screwdrivers are straight-handle type. Due to structural limitations, the shortcoming of the straight-handle type screwdriver is: the torque is small, and when removing the corroded and over-tightened screws, it is not only laborious, but also easy to dismantle the screws. Contents of the invention [0003] In order to overcome the shortcomings of the existing screwdrivers, the torque is small, and when removing the corroded and over-tightened screws, it is not only laborious, but also easy to dismantle the screws. The present invention provides a single-handle screwdriver, which has a large torque. When disassembling corroded and over-tightened screws, it not only saves effort, but also makes it difficult to dismantle the screws. [0004] The technical scheme that the present invention adopts to s...
