[0002] At present, a screwdriver is a tool used to turn a screw to force it into place, usually with a thin wedge-shaped head that can be inserted into a slot or notch in the screw head, called in the Beijing-Tianjin-Hebei-Shandong-Hebei and Shaanxi-Northern dialects "Screwdriver" is called "driver" in Jiangxi, Anhui, Hubei, Shaanxi Guanzhong, etc., it is called "changed knife" in the central and western regions, and it is called "rotary chisel" in the Yangtze River Delta. An easy-to-carry screwdriver, by setting the threaded column and the threaded cap, the rotating shaft of the forward and reverse motor drives the threaded column to rotate forward, so that the threaded cap drives the knife rod and the knife head into the interior of the handle, reducing the length of the screwdriver Small size, which makes the screwdriver more convenient to carry. Although this screwdriver can carry the screwdriver, the setting of the positive and negative motors makes the structural design more complicated, and the power supply of the positive and negative motors is not convenient enough, so the use of the screwdriver is not convenient enough.
