The invention provides a convenience screwdriver which comprises a screwdriver handle and a screwdriver rod extending downwards along the axis of the screwdriver handle. The lower portion of the screwdriver rod is composed of a section of silicon steel pillar, and a screwdriver bit is formed at the lower end of the silicon steel pillar. The silicon steel pillar is sleeved with a section of spiral spring, the upper end of the spiral spring is fixed, and the two ends of the spiral spring are electrically connected to a power supply structure in the screwdriver handle. In the natural state, a radial clearance ranging from 0.5 mm to 1 mm exists between the inner side of the spiral spring and the silicon steel pillar. By means of the convenience screwdriver, screws can be automatically picked, and in addition, magnetism can be automatically removed in the process that the screwdrivers are loaded into screw holes.
