The first person who describes the spiral is the Greek scientist Archimedes (about 287 BC - 212 BC) The Archimedes spiral is a huge spiral in a wooden cylinder used to The water is raised from one level to another, and the fields are irrigated. Its true inventor may not be Archimedes himself. Maybe he just described something that already existed. Perhaps it was the ancient Egyptian craftsmen who had designed it to use the irrigation on both sides of the river. Archimedes spiral in the ancient society are used to raise water, no one considered to change it into a fixed piece. Archimedes spirals are widely used for water lifting. For example, the Romans used it to drain the mine. In the Middle Ages, carpenters used wooden nails or metal nails to connect furniture and wooden structures. In the 16th century, nail workers began to produce spiral nails, these nails can be more firmly connected things. It was a small step from this nail to the screw. At the end of the eighteenth century, screws were quite popular as fixed parts, because at that time a cheap production method had been found. Screwdriver (chisel) appeared in London around 1780 years. The carpenter found that screwing the screw with a screwdriver was better than a hammer and could fix something better, especially when a fine screw was encountered.

Consists of countersunk head bolts, expansion tubes, flat washers, spring mats and hex nuts. When used, you must first use the impact of electric drill (hammer) in the fixed body on the corresponding size of the hole, then the bolt, expansion tube into the hole, tighten the nut to bolts, expansion tube, the installation and expansion between the fixed body Tight into one. Expansion of the expansion of the principle of expansion of screws is to use the pull out of the slope to promote the expansion of friction caused by clamping force, to achieve a fixed effect. Screw head is a thread, a vertebral. Outside the package of a metal, metal cylinder half of a number of incision, put them together thrown into the hole in the wall, and then lock the nut, Luo mother pull out the screw, the vertebral pull into the metal cylinder, metal cylinder was Open up, so tightly fixed on the wall, generally used for fence, rain Peng, air conditioning and other cement, brick and other materials on the fastening.
