Description
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 notch in the screw head. The dialects of Beijing-Tianjin-Hebei-Jin, Shaanxi, Shaanbei and northern Henan are called "screwdrivers", and northern Henan is more called screwdrivers. Jiangxi, Anhui, Hubei, areas south of the Yellow River in Henan, and Shaanxi Guan are called "screwdrivers". , The central and western regions are called "Gai Dao". There are mainly two types: a character (minus sign) and a cross (positive sign). Hexagonal screwdrivers are also common, including inner and outer hexagons. The screwdriver is used to pry the paint cover using the working principle of the lever. 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 and axle is used when the screwdriver is used to screw the screw. The larger the wheel, the more labor-saving, so the use of a thick-handled screwdriver is less labor-saving than a thin-handled screwdriver. Size: T9H. Shaft length: 80mm. An ordinary screwdriver is a screwdriver with a head and a handle. It is easy to prepare and can be used as long as it is taken out. However, because there are many different lengths and thicknesses of screws, it is sometimes necessary to prepare many different screwdrivers.
