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.

1. A screwdriver having a cable-stripping structure, the screwdriver comprising: a grip, including a combining portion having a receiving recess for allowing a screw-driving shaft to be inserted therein, wherein the combining portion further has a first cable-stripping groove, a first slit crossing the first cable-stripping groove, an engaging block having a recessed positioning segment defined between an end of the engaging block and the combining portion, and a fixing hole;a pressing plate, being combined with the combining portion of the grip, wherein the pressing plate has a through hole that has a circumference formed with an engaging recess for fittingly receiving the engaging block, so that the pressing plate is allowed to move along the positioning segment of the engaging block in a travel-limited manner, and wherein the pressing plate further has a second cable-stripping groove positionally corresponding to the first cable-stripping groove, a second slit crossing the second cable-stripping groove, and a holding hole positionally corresponding to the fixing hole; andtwo knives, each being respectively installed in the first slit of the grip and the second slit of the pressing plate, and each having a cable-stripping blade, wherein the cable-stripping blade of the knife installed in the first slit and the cable-stripping blade of the knife installed in the second slit are aligned with the first cable-stripping groove and the second cable-stripping groove, respectively. 2. The screwdriver of claim 1, wherein the first slit is normal to the first cable-stripping groove when crossing the first cable-stripping groove, and the second slit is normal to the second cable-stripping groove when crossing the second cable-stripping groove. 3. The screwdriver of claim 1, wherein the combining portion comprises four said engaging blocks that are separated and surrounding the receiving recess, while the circumference of the through hole of the pressing plate is formed with four said engaging recesses, so that each of said four engaging blocks is allowed to be fittingly received in a respective one of said four engaging recesses. 4. The screwdriver of claim 1, wherein the combining portion of the grip has two said first cable-stripping grooves that are two round-bottom grooves having different diameters, and the pressing plate has two said second cable-stripping grooves that are two round-bottom grooves each positionally corresponding to and geometrically identical to a respective one of said first cable-stripping grooves. 5. The screwdriver of claim 4, wherein the two first cable-stripping grooves are parallel to each other, and the two second cable-stripping grooves are also parallel to each other. 6. The screwdriver of claim 1, wherein the cable-stripping blade of the knife installed in the first slit and the cable-stripping blade of the knife installed in the second slit are sized and shaped in accordance with the first cable-stripping groove and the second cable-stripping groove, respectively. 7. The screwdriver of claim 1, wherein the combining portion has at least two said fixing holes having different diameters, in which the fixing hole having the smaller diameter is closer to a periphery of the combining portion than the fixing hole having the greater diameter, while the pressing plate has at least two said holding holes having different diameters, in which the holding hole having the smaller diameter is closer to a periphery of the pressing plate than the holding hole having the greater diameter. 8. The screwdriver of claim 1, wherein the periphery of the pressing plate is provided with a guiding groove corresponding to the holding hole.
