A rotatable hand tool includes a grip, a tool head, and a pivoting unit. The grip has a first pivot portion. The first pivot portion has a recess and a first tooth groove. The tool head has a second pivot portion. The second pivot portion has a through hole and a second tooth groove. The pivoting unit includes an elastic member, a positioning gear, and a button assembly. The elastic member is placed into the recess. The positioning gear is engaged with the first tooth groove and the second tooth groove, so that the tool head is retained at an initial angle. The button assembly is inserted in the through hole. The button assembly can be pressed to push against the positioning gear to disengage from the second tooth groove and compress the elastic member. At this time the tool head can be operated to pivot to a working angle.

A folding tool set includes an accommodating seat, a fixing shaft, many tools, many spacers, and an elastic member. The accommodating seat defines an accommodating space. The fixing shaft is disposed on the accommodating seat and has a polygonal radial section. One end of each tool is formed with a connecting hole through which the fixing shaft passes. The tools are pivotally connected to the fixing shaft and movably accommodated in the accommodating space. The spacers are spaced apart from each other and disposed on the fixing shaft. The spacers each have a through hole. The through hole corresponds in shape to the radial section of the fixing shaft. The elastic member is disposed on the fixing shaft. The elastic member has elasticity in an axial direction of the fixing shaft. When one of the tools is pivoted, the fixing shaft won't be driven to link the other tools.

A screwdriver having a cable-stripping structure has a grip provided with a combining portion having a first cable-stripping groove, and has a pressing plate combined with the combining portion and having a second cable-stripping groove positionally corresponding to the first cable-stripping groove. The screwdriver further has two knives each respectively installed in a first slit of the first cable-stripping groove and a second slit of the second cable-stripping groove and each having a cable-stripping blade aligned with a corresponding first cable-stripping groove or second cable-stripping groove, so that the pressing plate is allowed to move in a travel-limited manner along a screw-driving shaft inserted in the grip. The combining portion further has a fixing hole, while the pressing plate further has a holding hole corresponding in position to the fixing hole. Thereby the cable-stripping structure facilitates stripping and bending electric wires of different diameters.
