- Q: There are some screws, is installed in the electrical, power, electronic products on the material, ask how to correctly install the screws?
- Expansion screw installation method to expand the screw on the ground or wall holes in the hole, with a wrench to tighten the nuts on the expansion bolts, bolts to go out, while the outside of the metal sleeve is not moving, so the bolt under the bulk of the metal Set up to keep it full of holes, this time, the expansion of the bolt on the expansion of the expansion screw is to make the duct support, hanging, bracket fixed to the wall, the floor, the column used in a special thread connection Pieces. 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. But its fixation is not very reliable, if the load has a greater vibration, may be loose, it is not recommended for the installation of ceiling fans and so on.

(2) with a small amount of 502 glue into the screw hole, and then screw into the screw, and so the glue after the solid tip and then use the tip of the screw to pull out the screw (only the screwdriver is not afraid of causing screw teeth). (3) fruit screw cap exposed, you can use the tip of the clamp clamp screw cap after the screw. (4) the general mobile phone screws are metal, the case is plastic, not screw down when the time. You can use the tip of the screw into the screw cap, the metal screws to screw the plastic around the plastic melting, with the tip of the clamp clamp, gently pull out!

- Q: What is the invention of the screw?
- Screws Today, many things are screwed together. Look around the house, the eyes see all kinds of things - from furniture to food processors, are connected with screws. The spirits were invented more than 2,000 years ago, but less than 500 years for fixing things. The first man who describes the spiral is the Greek scientist Archimedes (about 287 BC - 212 BC). The Archimedean spiral is a huge spiral in a wooden cylinder that is used to raise water from one level to another and irrigate the fields. 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. Right: Archimedes spiral is widely used for water. 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.
