Abstract
The utility model discloses an adjustable screwdriver, which comprises a driver body and a bar. An incision hole is positioned on the driver body, and each incision hole wall is transversely cut for wedging and pulling out the driver bar. The inner wall of the body is provided with a plurality of first grooves, and an upper groove and a lower groove vertically locate under the first groove. On the outer wall of the bar, the plurality of first grooves match with a plurality of first bumps correspondingly, and the first bumps also match with the upper and lower grooves. One end of the bar is embedded in the first groove of the driver body through the plurality of first bumps, and, by moving in the related first groove towards the axis, locked in the upper groove or the lower groove for axial positioning. Because of the technical scheme, the user can adjust the length of the screwdriver according to the demand, which solves problems caused by the un-adjustable screwdriver.
Description
Technical field
The utility model relates to a kind of screwdriver that is used for the dismounting securing member.
