ABSTRACT:
A screwdriver handle includes a first handle part and a second handle part. An axle is formed on an end face of the first handle part and includes two receptacles each receiving a positioning member. The second handle part includes an end face pivotally connected to the end face of the first handle part and having a groove for receiving the axle. A positioning hole extends from a wall defining the groove through an outer periphery of the second handle part. One of the positioning members is biased into a retaining section of the positioning hole to position the second handle part. A control member is mounted in the positioning hole and movable to urge the positioning member in the receptacle aligned with the positioning hole into the receptacle, allowing the screwdriver handle to be switchable between an in-line state and an angled state.
