The principle of expansion screw fixation is that the principle of expansion screw fixation is to promote the expansion of friction force by using the stretching gradient to achieve the fixation effect. The screw is a thread, the end of the vertebrae. On one tin can of the outer package, the iron cylinder has multiple cuts. Melt them to the wall and throw them into the hole, then lock the nut, pull the nut out of the screw, and pull the vertebrae into the iron cylinder. The iron cylinder is opened upwards, so it should be firmly fixed on the wall, generally used for fastening the cement, bricks, etc. in the fence, awning, air conditioning and other materials. However, its fixing is not very reliable. If the load has great vibration, it may be loose. It is not recommended to install the ceiling fan.

The principle of the expansion bolt is that the expansion bolt touches the hole on the ground or wall, the expansion bolt is tightened with a wrench, the bolt goes out, and the outer side of the metal sleeve does not move, so most of the bolts placed under the metal sleeve will be opened to fill the hole, and the expansion bolt will not protrude.
