Abstract

The invention discloses a screwdriver capable of clamping screws made of any material. The screwdriver comprises a screwdriver body and a sleeve clamp. The sleeve clamp comprises two symmetric clamping pieces. The front ends of the clamping pieces are in an opening shape. Bent clamping heads are arranged at the front ends of the clamping pieces and provided with arc openings. Guiding holes are formed in the bending positions of the opening shapes of the clamping pieces. The screwdriver body is provided with pressing nails corresponding to the guiding holes. A handle is arranged at the tail ends of the clamping pieces. The two clamping pieces are connected through at least one pair of connecting plates. The screwdriver is simple and durable in structure, due to the fact that the handle is arranged on the holder side of the screwdriver, a screwdriver holder can be held by the palm during operation, the handle is operated by fingers, and one-hand operation is achieved; and the work efficiency is effectively improved, and the labor intensity is lowered.

Description

technical field [0001] The invention relates to the technical field of electrical tools, in particular to a screwdriver capable of clamping screws of any material. Background technique [0002] During the on-site maintenance of substations, it is often necessary to fasten screws with a screwdriver. Usually, one hand holds the screw and the other hand tightens it with a screwdriver. Yet then can not hold screw with hand under the narrow situation of space, and existing method is that screwdriver is magnetized, fastens after screwdriver is adsorbed screw. However, this method cannot be used for non-magnetic screws. When carrying out maintenance work in the substation, such a situation often occurs. At present, when encountering such a situation, the screw can only be placed in the mounting hole first, and then pressed and tightened with a screwdriver. Often, the screw is crooked. However, once the screw is crooked, it will need to be tightened again if it is light, and if it...
