A screwdriver is a common tool used to turn a screw into place. It usually has a thin wedge-shaped head that can be inserted into a slot or recess in the screw head. There are mainly two kinds of characters (negative sign) and cross (positive sign). Commonly used are hexagonal screwdrivers, including inner and outer hexagons. The screwdriver uses the working principle of the lever when prying the paint cover. The greater the distance from the power point to the fulcrum, the more labor-saving, so the long screwdriver is more labor-saving than the short screwdriver. The working principle of the wheel axle is used when the screwdriver is used to screw the screw. The larger the wheel is, the more labor-saving it is, so using a thick screwdriver is more labor-saving than using a thin screwdriver to tighten the screw.
