The principle of using the expansion screw is very simple, that is, the screw that has been fixed is made larger by the help of its screw. Apply pressure to objects such as walls completely, increasing their differential force. The pulling force of the screw is greatly increased to ensure the stability of the object to be fixed. The use of the expansion screw is to make the object more stable, the inclination of the screw and the expansion screw produce a larger differential force, thus achieving a more stable effect. One end of the screw is threaded and the other side is taper. The outer packaging is just a layer of iron. If half of the iron sheet has a cut, then put them together into the hole. After locking the nut, pull out the nut and open the tapped iron so that it can be tightly fixed to the wall. It is generally used in the protection of fences and canopies and air conditioners. However, sometimes the fixing is not completely reliable. If the load is large, it will easily fall off, so it is generally not used in the home ceiling fan fixing. The working principle of the expansion screw is to hit the expanded screw on the ground or in the mouth of the wall. Use a wrench to tighten the nut tightly, and the spiral will naturally go outward. However, the metal jacket will not move, then the metal sleeve will open under the spiral, so that the entire hole is full. At this time, with the help of the expansion screw, the work is much simpler. At present, the expansion screws have been widely used in the construction of the construction site, and it has helped to make the current fixed work more reassuring. Compared with before, it has a good effect and is widely recognized.
