"toggle bolt"的定义和意义

What is a "toggle bolt"?

A toggle bolt is a type of fastener used to attach objects to hollow walls or ceilings, such as drywall. It consists of a bolt with spring-loaded wings or toggles that fold back when pushed through a hole and then expand once inside the wall cavity, providing a strong anchor. The bolt is then tightened to secure the object in place. Toggle bolts are commonly used for hanging heavy items like shelves, mirrors, or light fixtures, where traditional screws or nails might not provide enough support.
