After tightening, it will expand. There is a big head at the end of the bolt. The outer sleeve of the bolt is a round tube slightly larger than the diameter of the bolt. There are several openings in the tail part. When the bolt is tightened, the tail of the big head is brought into the open tube. The pipe is made large, to achieve the purpose of expansion, and then the bolt is fixed on the ground or the wall to achieve the purpose of rooting.
