"glue gun"的定义和意义

What is a "glue gun"?

A glue gun is a handheld tool used for applying hot melt adhesive, commonly known as glue sticks, to surfaces. It heats the glue inside a nozzle and melts it, allowing the user to squeeze the trigger and apply the melted glue precisely where needed. Glue guns are widely used in crafts, home improvement, and light construction for bonding materials such as wood, fabric, plastic, and metal. They come in various sizes, with some designed for small, delicate tasks and others for larger projects.
