Stapler is a kind of mechanical equipment, which can connect sheet metal or similar materials by driving thin metal staples through the paper and folding both ends. Staplers are widely used in government, enterprises, offices, families and schools.

The word "stapler" can actually refer to many different devices for different purposes. In addition to connecting paper together, staplers can also be used in surgical environments to connect tissue to surgical staples to close surgical wounds (much the same way as sutures).

Most staplers are used to connect multiple sheets of paper. There are two types of staplers: manual and electric. Manual staplers are usually hand-held, although models placed on tables or other surfaces are not uncommon. There are many different designs and models of electric staplers. Their main operation function is to connect a large number of papers together quickly and continuously. Some electric staplers can connect up to 20 sheets of paper at a time. A typical stapler is a third lever.

A staple gun is usually a heavy hand-held device. It can be strictly manual or pneumatic. The binding gun is used to fix thin materials to a solid backing, such as a piece of paper on a bulletin board or a piece of wood. The two legs of the stapler of the stapler gun are not folded, but directly embedded in the liner material.
