Background

Anchors are typically elongate rods used to reinforce or simultaneously anchor in situ soil at a site. Usually, the concrete is made by drilling holes in the soil, placing deformed steel bars, i.e. ribbed steel bars, and grouting along the whole length of the holes. The anchor bolts are passively stressed under the condition that the soil body is deformed by means of interface bonding force or friction force between the anchor bolts and the soil body, and mainly bear the action of pulling force. The anchor can also be a steel pipe, an angle steel and the like, and is directly driven into the soil, and the anchor is commonly used as an R-shaped rivet, a fan rivet, a self-plugging rivet (core driving rivet), a tree-shaped rivet, a semi-circular head, a flat head, a semi-hollow rivet, a solid rivet, a countersunk head rivet, a self-plugging rivet and a hollow rivet, and the rivet is generally connected with a riveted piece by self deformation. Cold riveting, generally less than 8 mm, and hot riveting, generally greater than this size. There are exceptions, such as the name plate on some locks, which is riveted by the interference of the rivet and the lock body hole.

However, the conventional anchor is not capable of adjusting the length according to the thickness of the object when in use, and the anchor may be loosened during a long time use.
